Map of HDB blocks


The map is powered by HDB Blocks Database, an Excel file compiled by me that took about 500 hours of manual work.

Map made originally in September 2017 using Google Fusion Tables, a FREE experimental application that provided only 9 colors of colored dots, as well as other icons representing various businesses. Google announced closure of Fusion Tables on 3 December 2019.

In October 2019 I moved to ZeeMaps, a paid service that provide 31 colors to choose from, and ability to filter and display only blocks of specific criterias. If anyone thinks that is better to use different colors that indicate block types and construction years, please tell.

HDB price trends

HDB Resale Price Index DOUBLED from 2007 to 2013, dropped slightly to 2015 then stabilized. However, due to high supply of flats completed in 2014-2017 that enter on resale market since 2019, prices are likely to drop more in the coming years.

HDB resale flat prices 1990-20209

I am surprised by the 0.5% increase in 4th quarter of 2019 against logic that contradict my prediction, does fall ended and another price bubble is coming in 2020? At same time, Coronavirus death toll exceeded 1000 on 10 February 2019, killing for first time 100+ people in one day. Depending if this continue to spread exponentially and more cities in China enter in quarantine, country economy may collapse and cause a chain reaction leading whole world to another recession like in 1997 or 2009.

Actually prices are rising in some towns while dropping in other towns. The below charts generated from Excel analysis shows price evolution for each town. HDB do not provide median price if less than 20 flats were transacted per quarter, thus there are gaps in lines. Especially in case of Executive flats, HDB do not display median prices for Bishan and Queenstown (towns famous for $1 million HDB flats) because they do not have at least 20 transacted flats except in Q2-Q3 2008.

In 2013 I sourced data from HDB Resale Statistics and compiled an Excel file showing HDB price trends since 2007, and based on it I created the below charts which I am updating every quarter. Due to requests from 3 people, in 2020 I compiled similar Excel file sourcing data from HDB rental statistics. See below video what do you get after payment.

Price trends in 1990s and 2000s

During 1990s, the location was not so important. Like today, Bishan and Bukit Timah had the most expensive resale flats, but a thing less known by the young generation, is that Choa Chu Kang and Pasir Ris were also among expensive estates. Mature towns like Queenstown, Toa Payoh and Ang Mo Kio were cheaper.

Larger flats types had higher price per square meter or feet than small flats, in 1990-1992 average resale price of Executive flats being double than average resale price of 4-room flats, at an area 40% larger.

HDB stopped deciding the prices of new apartments based on construction costs, instead they decided based on market prices. Prices of resale flats and new flats entered in a vicious circle, rising 50% in just 6 months of 1993 and tripled to 1996. The gap between small and large flat types in terms of price per square feet has decreased.

The 1997 Asian Crisis came when 80.000 flats were under construction, demand for new flats felt sharply. leaving HDB with about 40,000 unsold completed flats in the year 2000, mostly large flat types. 2003 SARS outbreak affected economy too. Queue selling system (Registration for Flat) was suspended in 2002, Build-To-Order was introduced to prevent oversupply, and Walk-In-Selection was used between 2002 and 2007 to clear the stock of unsold flats.

The old estates built in 1960s and 1970s suffered from dilapidated buildings, aging population and businesses moving out, so HDB launched various upgrading programmes and Selective En-bloc Redevelopment Scheme to bring them in the line with new estates. Resale flat prices in old estates (where most 3-room are located) started rising in 2002, while in new estates they continued to fall until 2006, Executive flats having biggest fall. Price per square foot between small and large flat types equalized in 2005.

Walk-In Selection ended in 2007 and was replaced by Sale of Balance Flats that is only twice per year and in some towns more than 10 people battle per each flat. BTO became main mode of flat supply. People who cannot wait 3-4 years construction time for BTO and fail at SBF, need to go in resale market. Resale prices started rising.

Prices grew faster in pre-1980 estates fueled by upgrading programmes and agents lying people that all old blocks will get SERS, making prices in Marine Parade, Queenstown, and Toa Payoh to rival those in with Bishan and Bukit Timah. Pasir Ris had lowest price growth.

Singapore economy recovered in late 2000s but HDB failed to anticipate, it ramped up the BTO supply too late and too slow, they offered 5500 BTO flats in 2007, 7800 in 2008, 9000 in 2009 (global recession), 12000? 16000 in 2010, 22000 25000 in 2011, 25000 27000 in 2012, plus DBSS flats and Executive Condos. (strikethrough numbers are initial numbers announced at beginning of year).

Rising supply of BTO became visible in 2012, a small reduction in resale prices growing rate.
HDB lowered minimum application rate for BTO to be built from 70% to 50% in 2011, but since mid-2000s to 2013 no BTO had application rate under 100% (except elderly Studio BTO flats).

Analysts predicted that the prices in Singapore will start dropping in 2012 (example), as they predicted in 2011, 2010 too. In my forecast, resale flat prices will NOT fall even in 2012, but will continue to grow for as many years as HDB refuse to build ahead of demand, forcing us to wait 4 years via BTO!

HDB introduced multiple measures to cool down the market, but all failed, for example Minimum Occupation Period lengthen to 5 years for resale flats in 2011 (does anyone know when 5-year MOP was introduced for new flats?) just made less flats to enter resale market and the number of people not eligible for buying directly from HDB (for example PR and singles) is growing.

Most of BTOs launched in the 3 years 2009, 2010, 2011 been completed in only 2 years 2013-2014… 25000 flats completed in 2014 alone + 5 years MOP = possible market crash in 2019. I am not saying that prices will not start to fall earlier, but 2019 may have the biggest price fall (if other variables would not exist).

Note: The above text was written by my personal research at end of 2011. Later I found a similar research on h88.com.sg: Colin Tan: HDB resale flat prices will stay up, dating from Feb 2012, that confirm my hypothesis They say that prices will drop no sooner than 2017! Oh dear…

Prices dropping since 2013

One of the cooling measures, 3 year waiting period for permanent residents to buy resale flats, introduced in August 2013, created fear that the housing market may crash. Resale flat prices dropped in 3rd quarter 2013, for the first time in 5 years. Such minor drop in prices may cause panic, many owners rush to sell their flats before prices fall more, leading to a chain reaction in price drop, OR if the panic may be just temporarily and prices will rise back next year. However, there are no signs to recover. Every quarter of 2014 added 1-2% drop in prices. No significant drop but still enough to make analysts ANGRY that HDB cooling measures were too powerful and requested to be lifted.

Note that HDB can also invent anti-cooling measures in case prices drop with more than 10% in one year, and these anti-cooling measures can fail as most of the cooling measures failed. HDB wants to stabilize prices, a too sudden drop can be disastrous for entire Singapore economy.

Stupidity: instead of providing an adequate supply of flats, they kept supply low during 2000s despite of population increase, and while demand was rising too few flats entered in resale market, then during 2010s HDB artificially slowed down demand for resale flats with cooling measures, and when prices started to drop, instead of keeping supply high and lift the cooling measures, they announced to decrease supply of new BTO flats 24300 units in 2014 to 16900 units in 2015. A stupid decision! BTO launches do not affect resale prices directly so we expect to see prices dropping and further decrease of BTO supply in the next years, thus the 2008-2013 price bubble risk to happen again during 2020s!

Personalty I hope that HDB will let the price index to drop slowly to 150 (2009 level), THEN lift the cooling measures, but keep the supply of at least 25000 BTO flats per year.

New BTO flat prices won’t fall according resale price index, they were traditionally priced 20% cheaper than nearby resale flat prices, but since 2011 they were “de-linked” and became 30-40% cheaper (even if we exclude grants for first timers) as the HDB anticipated market fall. Even if the prices fall 10% for 3 consecutive years, BTO flat owners will still have profit from selling their flats. This does not apply for DBSS flats which were overpriced at their launch in 2011-2012. Raised income ceiling from $10k to $12k in 2015 may allow HDB to push up BTO prices. Income ceiling was raised again to $14,000 on 10 September 2019 (source).

https://kendata12345.wordpress.com/category/4-hdb-bto-flats-price-and-cost-analysis/ – Another website did a detailed analysis of cost of building a BTO flat compared with selling price. He copied my Excel file of BTO prices without my approval.

What you should know

– Upgrading programmes and upcoming MRT lines also drive up the nationwide resale price index.
– The small size of today flats may encourage people to go in resale market for flats built before 1998 (NOT SURE if this push up the resale prices, record of psf is now hold by resale flats built in 2000s).
– Prices fall faster in young towns than mature towns, Punggol suffered biggest price fall in late 2013, as results of over-speculation during last years, this after it was the cheapest town in mid-2000s.
– In mature towns prices fall faster in the old 10-storey blocks of Queenstown and Toa Payoh that are getting shadowed by the new 40-storey blocks.

Affordability of HDB flats

Yes they are still affordable!
Proof: every launch, the higher priced BTOs (better locations) gets most applicants.
HDB Website shows application rate. See how 3-room remained unsold and how big is the battle for 5-room despite of higher prices. See the TRUTH about shrinking HDB flat sizes!


As you can see in the chart, Singapore HDB flat prices DOUBLED in 2008-2013 due to insufficient supply of new flats.

Would you like prices dropping next 5 years to the early 2000s value? Think about owners who worked hard to pay current flats which will lose half of value! Would you like prices growing so you and everyone else can make profit selling? Think about your kids, how hard they will need to work to buy their first home!

If you could decide HDB flat prices to fall or rise, what you would do?

10-20% price rise per year to ensure that every flat owner can make profit when will sell the flat. Forget our children and other young couples
max 5% price rise per year
Maintain prices as constant is possible
max 5% prices fall per year
10-20% price fall per year to quickly make the flats affordable for our children. Forget the current owners which will lose money, but public housing is not meant for investment and profit

1930s, 1940s, 1950s – SIT era

Tiong Bahru pre-war vs post-war SIT blocks
Tiong Bahru pre-war SIT blocks Tiong Bahru post-war SIT blocks

Singapore Improvement Trust set up in 1927 and focused on infrastructure, it also built small scale public housing, such as Tiong Bahru (started in 1936) and Queenstown (started in 1952 and completed by HDB in 1960s). In 32 years, SIT built only 23,000 flats, housing 8.8% of Singapore population in 1959.

The SIT housing was similar with British housing, 2-storey terraced houses, 3/4-storey walk-up flats, 7/9-storey high-rise flats started being built in 1952 and one 14-storey block was built in 1956 in Queenstown. The blocks were built at just 10-15 meters apart, denser than HDB estates. List of SIT estates.

SIT floor plans

Pre-war Tiong Bahru blocks feature flats from 3-room to 5-room, you can see floor plans on https://tiongbahruestate.wordpress.com/2007/06/29/tiong-bahru-pre-war-floor-plans/ and https://tiongbahruestate.wordpress.com/category/uncategorized/

Post-war, SIT built mostly 2-room and 3-room, a small number of 4-Room flats were built at least in Alexandra North, Silat Estate and Tiong Bahru, but I never found any floor plan. To speed up construction, flats were downsized in 1955 and fewer 4-room were built. 1-Room flats on double-loaded corridor were introduced in 1958 in Kallang Airport Estate. SIT also built tenements (blocks with communal kitchen and toilets, opposite of “self-contained flats”), that can be built quickly for the victims of various fires.

Tiong Bahru 2-Room Tiong Bahru 3-Room (77 sqm) Redhill Close 3-Room (63 sqm) Tiong Bahru 3-Room (88 sqm)

SIT also built terraced houses, two clusters survived: Jalan Bahagia (in Whampoa, 28 blocks, 200 units), Stirling Road (in Queenstown, 13 blocks, 84 units). Most units are 3-Room (originally 78 sqm) but on Stirling Road there are some 4-Room (99 sqm). Over time, the owners built additional rooms in front, rear, and side of corner units, expanding some houses to over 200 sqm according resale transactions.

Some floor plans of rental flats are available on HDB InfoWEB under PPHS (whole block floor plans, no dimensions).

1960s – HDB beginnings

HDB was founded in February 1960, shortly after People Action Party won national elections of 1959. HDB continued construction of some SIT estates: Queenstown, Kallang Airport, St. Michael, Kampong Tiong Bahru, and launched new estates like Bukit Ho Swee, Brickworks, Alexandra Hill, Redhill, Henderson (in Bukit Merah); Bendemeer, Boon Keng, Kallang Bahru and Tanjong Rhu (in Kallang), Upper Changi Road aka Chai Chee (now part of Bedok), MacPherson (in Geylang), MacPherson Homes (in Toa Payoh).

On 13 February 1959 a fire started in Kampong Tiong Bahru, leaving 12,000 people homeless (source: NLB). SIT quickly cleared the area and built few 5-storey blocks with 1-Room flats and 9-storey blocks as well as terraced houses. A bigger fire in Bukit Ho Swee on 25 May 1961 left 16,000 people homeless, as coincidence HDB completed in September 1961 the Kampong Tiong Bahru flats started by SIT and moved the fire victims there, after few months of temporary housing in Queenstown. These fires helped HDB to gain popularity.

In Master Plan 1958 you can see numerous terraced houses (planned by SIT and never built) around Redhill and Whampoa. HDB changed housing typology to massive blocks with smaller flats and eliminated terraced houses.

HDB aimed to build 50,000 dwelling units in first 5 years, so a simple brutalist architecture was chosen, in contrast with the Art Deco and Modernist themes used by SIT. Kampong clearance started.

Queenstown was de facto first new town, but Toa Payoh New Town started in 1965 was the first officially named “New Town”), incorporating a town centre and several neighborhoods. Toa Payoh preliminary plan was published in SIT Annual Report 1958, including terraced houses and low-rise flats. Farmers that opposed government taking their land delayed construction for few years, enough for HDB to change plans to high rises.

The first blocks completed by HDB are Queenstown blk 45, 46, 49, 7-storey blocks styled like SIT.

Redevelopment of uneconomical SIT estates started in 1967, single-storey artisans quarters built by SIT in 1951-1953 at Henderson and Upper Aljunied were demolished and replaced by high-rise blocks.

1960s estates composed only by linear slab blocks (corridor style) in most common height of 10 storeys and usually with 12 units per floor, but several blocks were longer, plus 2-storey shophouses. Minimal distance between facades was not regulated, usually 15-30 metres.

1960s typical HDB floor plans

In first 5 years HDB built flats in proportion of 40% 1-room, 30% 2-Room, 30% 3-Room. The floor areas have broad range: 1-Room (23-33 sqm), 2-Room (35-45 sqm), 3-Room (50-70 sqm). 4-Room were introduced in 1967 at Henderson Road. Later in Outram Park and Toa Payoh (70-85 sqm). I estimate average size during 1960s around 40-50 sqm.

Standard flats (1/2/3/4-room) had WC and shower in same room.

Improved flats (1/2/3/4-room) were introduced in 1966, the 3/4-room having separate WC and shower, they also featured void decks.

Emergency flats (1/2-room on double-loaded corridor) were also built. I do not know how many emergency blocks were built, because only 5 blocks survived: blk 91, 92, 93 Henderson Rd , blk 1 Maude Rd, blk 2 Kitchener Rd (2-room, all rental). The typology with double-loaded corridor was used also for 1-Room Improved.

Tenements (flats with communal kitchen and toilet, opposite of self-contained flats), were also built, for example Bukit Ho Swee blocks 1, 3, 5, 7, 9, according iremember.sg blog (I do not know if these were all tenements or if were more).

1960-1970 slab blocks with 2-Room Standard (44-45 sqm), 3-Room Standard (50-55 sqm), 4-Room Standard (70-75 sqm)
Most blocks of this type were upgraded with utility rooms, some with bedroom extension including en-suite toilet.

1966-1980 slab block with 1-Room Improved (33 sqm)
The ONLY remaining 1-room home ownership block is blk 7 Telok Blangah Crescent, two more blocks did existed but got SERS: blk 309 Ang Mo Kio Avenue 1 and blk 33 Taman Ho Swee. All other 1-room blocks are rental. Some of them are 2 meters wider, flats 6096 mm long instead of 5486 mm, toilet is squarish and kitchen is L-shaped around toilet, having 2 windows (example blk 123 Bukit Merah View). No floor plans available, because HDB never provide floorplans for rental flats.

Most blocks of this type were upgraded with 5-6 sqm utility rooms, these utility rooms vary in shape and size so that is why I posted here original floorplans without utility room.

JTC floor plans

Jurong Town Corporation established in 1968 and built 5 estates in parallel with HDB:
Taman Jurong, built 1964/1969-1974, most demolished in 1990s and 2000s). Earliest blocks were built by Economic Development Board in cooperation with HDB starting from 1964, then JTC took over in 1969.
Boon Lay Gardens, built 1974-1978, mixed with HDB, most demolished in 1990s and 2000s.
Teban Gardens, built 1977-1978, mixed with HDB, some demolished in 2000s.
Pandan Gardens, built 1978-1979, all survived.
Sembawang, built early 1970s, 7 blocks, demolished in 2004.
The 5-Room flats built by JTC feature 2 entrance doors!

1970s – HDB new towns

Concept Plan 1971 featured a ring of New Towns around Central Water Catchment and a provisional plan for two MRT lines to be built by 1992.

In 1970s seven new towns were started: Ang Mo Kio 1975, Bedok 1975, Clementi / West Coast 1977, Hougang 1974 (only several blocks), Marine Parade 1974, Telok Blangah 1973, Woodlands 1973 (Marsiling estate). Toa Payoh was extended (blocks 210-235).

In addition, small estates were started: Kallang Basin (1960s?) and St. George 1975 (in Kallang); Geylang East 1974, Haig Road 1975, Jalan Eunos 1976, Sims 1974 (in Geylang); Dover 1975, Ghim Moh 1975, Holland Village 1973 (in Queenstown); Farrer Road 1973 (in Bukit Timah), Hillview 1977 (in Bukit Batok, demolished in 2005), Teck Whye 1977 (now part of Choa Chu Kang), Lorong Lew Lian 1977 (in Serangoon), Sin Ming 1973 (in Bishan), Nee Son 1977 (now part of Yishun).

1970s generation estates were dominated by massive slab blocks, majority 10-16 storeys and usually with 14 or 18 units per floor, most were over 100 metres long, plus point blocks, majority 25 storeys, and 4-storey blocks with shophouses. Minimal distance between facades was 30 metres.

HDB also built Rural Centres, mini estates with <4-storey blocks and several hundred flats to house farmers: Changi Village (considered in Pasir Ris), Kranji / Lim Chu Kang (abandoned in 2001), Punggol Road End (in Sengkang area, demolished in 2005-2007), Seletar Road (in Serangoon area, demolished 2005), Seletar West Farmway (in Sengkang area, demolished 2004).

1970s typical HDB floor plans

In 1975 were completed the first New Generation flats: 3-Room (67 / 82 sqm) and 4-Room (92 sqm), compared with Improved flats, the NG flats feature en-suite toilet for master bedroom, with pedestal type WC, plus store room (source: Straits Times 29 Aug 1973). This article HDB Floor Plans 1930-present is copyrighted by www.teoalida.com.

Point blocks, taller than surrounding blocks and having only 4 units per floor, the first had 3-Room flats, 2 were built in 1970 on Mei Ling Street and 2 in 1971 on Bendemeer Road, followed by 4-Room Improved (84 sqm) point blocks in 1973 and 5-Room Standard point blocks in 1974.

First 5-room flats (117-125 sqm), Standard and Improved were completed in 1974, in point block form. Starting from 1976, 5-Room flats were offered also in slab block form. All 5-Room flats feature master bedroom with attached toilet with pedestal type WC.

By mid-1980s 2 with 3-Room, 26 with 4-Room and 239 with 5-room. Blocks with 4 units per floor continued to be built in late 1980s, but height similar with surrounding blocks made me to not include them in above figure.

3/4-Room Standard flats disappeared in early 1970s, Improved flats disappeared too in late 1970s. The average size rose from 60 sqm in early 1970 to 75 sqm in late 1970s estates.

Marine Parade was, and is still the most prestigious HDB estate, also the oldest HDB estate remained intact (no demolitions, no new blocks). Built in 1974-1976, it contains 7898 dwelling units in 56 blocks, slab blocks with 2/3/4-Room Improved flats plus 17 tower blocks, each with 96 units of 120 sqm 5-Room Standard flats. Average flat size: 76 sqm, a record for its time (today average size is a little bigger due to upgrading with utility rooms and many 3-room flats adjoined.

1980s – More HDB new towns

In early 1980s nine New Towns were born: Bishan 1984, Bukit Batok 1982, Hougang 1980, Jurong East 1980, Jurong West 1981, Serangoon 1983, Tampines 1981, Woodlands 1980 (integrating Marsiling estate), Yishun 1981 (integrating Nee Son), as well as small estates: Kaki Bukit 1985 (in Bedok), Bukit Purmei 1982 (in Bukit Merah), Ubi 1984 (in Geylang), McNair 1982 (in Kallang), Potong Pasir 1983 and Upper Aljunied 1982 (in Toa Payoh).

In the late 1980 four more New Towns were born: Bukit Panjang 1986, Choa Chu Kang 1987 (integrating Teck Whye), Nanyang 1986 (extension of Jurong West), Pasir Ris 1987, as well as Estates: Simei 1987 (near Tampines), Kembangan 1988 (in Bedok), Toh Yi 1987 (in Bukit Timah).

1980s towns were composed by slab blocks with 10-13 floors, usually with 10 or 12 units per floor, plus point blocks with 20-25 floors, but also many 4-storey blocks. After 1985 just few blocks were built with more than 13 storeys. Compared with previous decade, the blocks were arranged in more rigid patterns, with corners bend to give the precinct a sense of enclosure. Most 10-13 floors blocks were perfectly aligned to east-west direction to avoid sun, surrounded on east and west sides by 4-storey walk-up blocks. Minimal distance between facades was 24 metres.

Ground floor units were reintroduced, most 1980s high-rise blocks have few (usually 4) units at ground floor while rest of floor is void deck. Most 4-storey blocks do not have void decks.

Prefab block vs non-prefab blockIn 1980 first prefabrication contract was awarded, raising the construction ratio to about 190,000 flats built in 1981-1985, the record being 67,856 flats in 1984. Prefab blocks were built in 16 months, 20% faster than 20 months for normal blocks (source: Straits Times 1982).

These 1980s prefab blocks with load-bearing walls can be identified by being uglier, having simple floorplan, plain external walls (unlike normal blocks which have columns visible on facade and windows pushed back). Prefab flats have lower value than non-prefab blocks, hacking walls is not allowed except a door-size opening, ceiling leaks are common.

A confusing thing: today BTO blocks use prefabricated panels too, but does not look similar with 1980s blocks, construction time is double, 3-4 years, and internal walls can be hacked. Probably they were referring that in 1980s they made blocks entirely prefab, load-bearing prefab walls.

Rising home ownership left rental blocks empty. Most blocks with Emergency flats built in 1960s were demolished in 1980s and land was redeveloped into 3-Room to Executive flats.

The percentage of population living in public housing hit the all-time record of 87% in 1988-1990, construction ratio had to be reduced to 10,000 units per year in 1989-1991 to avoid oversupply, leaving some estates unfinished, for example Yishun 4xx with its 8 blocks surrounded by open space.

1980s typical HDB floor plans

Along the 3/4-Room New Generation and 5-Room Improved, in 1981 were introduced Model A flats: 3-Room (75 sqm), 4-Room (105 sqm), 5-Room (135 sqm), 5-Room Maisonette (139 sqm), and in 1984 were introduced Simplified flats, 3-Room (64 sqm), 4-Room (84 sqm).

Executive Apartment / Maisonette (146-150 sqm) were introduced in 1983 and replaced 5-Room Model A flats, in addition of the 3-bedroom and separate living/dining found in 5A flats, EA and EM feature an utility/maid room. 80% of Executive units were Maisonettes and 20% were Apartments.

New types of 4-Room Model A, 5-Room Improved, Executive Apartments / Maisonettes were introduced in 1987, the 5-Room and Executive having 4 bedrooms instead of 3 bedrooms (plus utility room in Executive), (source: Straits Times 1984).

Multi-Generation flats were 3/4-Room Simplified blocks reconfigured into 3-bedroom + Studio (granny flat), having 2 entrances and an internal door that join flats. The granny flat was not used as intended so the concept was abandoned after building only 8 blocks in 1987: Bishan 137, 148, Tampines 454, 460, Yishun 605, 632, 633, 666 (source: Straits Times 1986 + Straits Times 1988).

Rising popularity of bigger units left HDB with many unsold small flats. Last 1/2-Room Improved were in 1985 (Tampines 441, 442, 466, 471, all rental). Last 3-Room Improved and 3/4-Room New Generation were built in 1986. Last 3-Room Model A was built in 1987. Last 3/4-Room Simplified was built in 1988. Few blocks of 3/4-room flats were converted into 5-Room and Executive flats, popularly called “Jumbo flats” (source: Straits Times 1989). Average HDB flat size for early 1980s estates is 90-100 square meters, and 120 sqm in 1991.

Despite that at least 10,000 dwelling units were completed each year, very few flats have leases 1990 and 1991. Number of flats with lease 1991 is about 6% of the number of flats with lease 1989 and 1992 according my analysis of resale transactions. A possible hypothesis is that HDB changed the purchase scheme and lease started later than actual completion date (can someone confirm?).

Staircase landing is at middle of block, making lift upgrading unfeasible. Many such blocks did not got LUP.
First blocks with lifts stopping at every floor were announced in in Straits Times 1989 and was completed in 1992, featuring staggering corridors to offer privacy to at least 50% of units and direct lift access to at least 80% of units.

1990s – The modern HDB blocks

In the early 1990s extensive construction was done in Choa Chu Kang, Hougang, Pasir Ris, Tampines, plus small additions in many other towns.

In the late 1990s three New Towns were started: Sembawang 1997, Sengkang 1997, Punggol 2000. Construction stopped for Tampines and Pasir Ris in 1995 (why?) but continued for Bukit Panjang, Choa Chu Kang, Hougang, Jurong East (Toh Guan Road), Jurong West (Pioneer area), Woodlands (Admiralty).

In mid-1990s majority of blocks range between 10-16 storeys, while blocks with household shelter built after 1998 range between 12-18 storeys, a small number of blocks have up to 30 storeys. Walk-up blocks almost disappeared. Unfortunately minimal distance between blocks was reduced to 18.3 metres (60 feet).

1990s was a decade of rapid development and innovation, raising the standard of living in public housing of Singapore to a level similar with private housing in other countries:

1992 – all blocks completed in 1992 have lifts stopping on every floor now and centralized refuse chutes (until 1993 some blocks have lift machine room at top floor so the flats at top floor do not have direct lift access).
1995 – introduction of yards for kitchens and by-panel main door.
1997 – introduction of household shelters and A/C ledges placed opposite of kitchen window, that double as second support for drying on bamboo poles.
2000 – first blocks competed in Punggol, a town built almost without corridor-facing flats (except 4 blocks and rental blocks built in 2010s) and green roofs on every MSCP.
2003 – last corridor-facing flats were completed (Sengkang blocks 207A-D).

1990s blocks are highly decorated and grouped in precints with distinctive styles, ground car parks were replaced by multi storey car parks, this allowed higher density, taller blocks, and more green space. All blocks are linked by covered walkways with car parks, bus stations and other facilities, so you can go anywhere regardless if the sun is too hot or is raining.

Since 1988 structural elements became thicker, 30 cm or more, rather than 20 cm in 1980s blocks, and more pillars per block. I do not know if this design is to withstand earthquakes.

Design & Build scheme was introduced in 1991, calling private architects to inject more variety into public housing designs (source), first project being at Tampines 230A-J (1992), featuring curved facades.

Design Plus followed in 1996.

Premium Apartments were introduced somewhere during 1990s, featuring better quality finishes, you get them in ready-to-move condition, with flooring, kitchen cabinets, built-in wardrobes? (compared with Standard Apartments where you get raw concrete waiting for your renovation).

Executive Condominium scheme was launched in 1995 (source: HDB Press Release 29 August 1995), subsidized private housing with facilities like private condos and same eligibility conditions like HDB (family nucleus, citizens and permanent residents, income ceiling). After 10 years since TOP date, all restrictions are lifted and even single foreigners can buy EC. See List of EC.

All premium contracts feature unique floor plan and corridor-facing flats are avoided. Since early 2000s standard contracts also became unique, putting the END to privacy issues of corridor-facing flats.

More and more land parcels were sold to private developers, making the percentage of population living in public housing to fall. Privatization of the former HUDC estates started in 1995 too.

The old HDB estates built in 1960s and 1970s suffered from dilapidated buildings, aging population and businesses moving out. On resale market Queenstown and Ang Mo Kio were cheaper than Pasir Ris, one of the cheapest towns today (source: analysis of Resale flat prices database). To prevent this, HDB launched Main Upgrading Programme in 1990 to improve pre-1980 estates, adding extra bathrooms for Standard flats, utility rooms, lifts that stop on every floor, redesigning facades for more modern look, building multi-storey car parks and converting surface car parks into green space, building covered walkways, etc. Interim Upgrading Programme was launched in 1993 for blocks built in 1980s, doing only small external upgrades.

Although small-scale redevelopment of old estates started in 1966, with demolition of single-storey artisans quarters, a massive demolition of 1-room rental blocks occurred in 1988-1989 and continued into 1990s, it freed up land to build new blocks with 5-room and Executive units in mature estates like Bukit Merah, Queenstown and Toa Payoh. The HDB Floor Plans 1930-present is copyrighted by www.teoalida.com.

Remaining rental blocks were converted, units adjoined, creating units up to 192 sqm (3-rm + 4-rm) unofficially called Jumbo Flat and sold with fresh leases from 1992 to 1996. Since 1994 flat owners were allowed to buy an adjacent flat and adjoin them, but only for 3-room or smaller flats, officially called Adjoined Flat.

Selective En-bloc Redevelopment Scheme was announced in 1995 to demolish selected owner-occupied blocks built up to 1980 and rehouse the residents in new blocks built in nearby location, to maintain community. Usually low-rise blocks with large spaces between them are selected for SERS while dense and tall blocks are selected for upgrading. HDB do not give you a replacement flat automatically, they compensate you at market value, then you need to buy yourself a subsidized flat in replacement blocks which can be smaller or larger, and pay the difference with CPF. Since 2004 the residents can enjoy SERS benefits buying new flats anywhere instead of being limited to the designated replacement blocks. Redhill Close (built 1955) was the first upgraded blocks (MUP 1992) to be selected for SERS in 2011. See List of SERS sites.

HDB stopped deciding the prices of new apartments based on construction costs, instead they decided based on market prices. Prices of resale flats and new flats entered in a vicious circle, rising 50% in just 6 months of 1993 and tripled to 1996, then felt down 30% to 1998 and continued to fall in non-mature estates by 2006, while in mature towns they started rising in 2002, fueled by upgrading programmes and agents lying people that all old blocks will get SERS.

1990s standard HDB floor plans (centralized refuse chute era)

1990s HDB flats provide high variety of layouts in various sizes: 4-Room Model A (100-108 sqm), 5-Room Improved (120-128 sqm), 5-Room Model A (133-137 sqm), Executive Apartment / Maisonette (142-150 sqm). Share of 5-Room and Executive flats increased, raising average size of new flats to over 120 square meters in 1991-1996 (even 130 sqm in 1994-1995 due to Jumbo converted blocks).

An experiment with 2-Room flats was done in 1994 (Pasir Ris block 142), having 2-room units on ground floor and 4-room on rest of floors.

Jumbo and Adjoined HDB Flats

Jumbo Flats: blocks taken back by HDB, flats joined into bigger flats and resold with fresh leases (1992-1996), they appear in HDB Resale Transactions as 4-Room Model A, 5-Room Improved / Model A, Executive Apartment and you cannot tell which of them are the jumbos.

Most Jumbo flats are in Woodlands and Yishun, few are in Tampines, Jurong East, and Ang Mo Kio (only smallest type from 2-room blocks). Their size vary from 90 sqm (2-Room + 2-Room) to 189 and 192 sqm (3-Room + 4-Room Model A), up to 7 rooms (5 bedrooms) and 3 toilets (source: Straits Times 1989). Unlike the 1980s Multi-Generation flats, Jumbos DO NOT have 2 entrances or 2 kitchens.

Adjoined Flat: flats joined by owner of a 3-room or smaller flat who bought adjacent flat, they appear in HDB Resale Transactions as 4-Room / 5-Room / Executive Adjoined Flat. Adjoined flats CANNOT be 3-rm + 4-rm, can have 2 entrances but most owners walled one entrance.

Two examples of (Jumbo) Executive Apartment created from one 3-rm with one 4-rm, and one example of converting three 3-Room Simplified flats into two 4-rm flats.

Late 1990s floor plans (household shelter era) – First downsize of HDB flats

Another revolution is visible for the HDB flats completed since 1997: Block naming system (slab, point, atrium) has been abandoned. Flat naming system (Improved, Model A, etc) is no longer used in sale brochures, where a new naming system was introduced: Type A = 4-rm, Type B = 5-rm, Type C = Executive and the word Flat was replaced by Apartment. Resale transactions still show old flat type naming, and after 1998 all 4-rm are Model A and all 5-rm are Improved.

The flat sizes were standardized, slightly smaller: 4-Room (100 sqm), 5-Room (120 sqm), Executive (140 sqm). Percentage of EM was reduced compared with EA because of aging population who do not like stairs (source: Straits Times 1989) and the last maisonette was completed in 2000.

The 5-Room lost the study area, being just a 3-bedroom flat with larger living room. Executives are 3 bedrooms plus open study area that can be walled into a 4th bedroom. Average flat size 110 sqm.

A household shelter was provided in every flat, a store room with strengthened 30 cm walls and sealing door. Useless feature in my opinion, the shelter eats about 5 sqm, sometimes placed in middle of flat, hacking it is not allowed making floor plan less flexible (some exceptions in 2000s: all 1/2-rm rental blocks and some 2/3-rm sold blocks have a common storey shelter instead of household shelter inside flat).

1997-1999 block with 4-Room Model A (100 sqm), 5-Room Improved (120 sqm) and Executive Apartment (140 sqm), some blocks have 4-Room Model A2 (90 sqm)

Second downsize of HDB flats

All HDB flats completed since 2000 lost 10 sqm, their sizes being 4-Room (90 sqm), 5-Room (110 sqm), Executive (130 sqm, 125 sqm after 2003).

In attempt to reduce number of corridor-facing flats, the shape of blocks became complex, with many corners where 5-Room units are located. In 2002 and 2003 the number of 5-Room flats exceeded 4-Room, so the average flat size remained high as 105 sqm in 2000-2005.

1999-2003 block with 4-Room Model A (90 sqm), 5-Room Improved (110 sqm) and Executive Apartment (130 sqm in 1999-2001, 125 sqm in 2002-2003)

2000s – The decline

During 2000s, no other New Town or Estate were started. Construction continue only in existing estates. Taller and taller blocks were built in all estates not too close to airports to have height constraints. 30-storey complexes appeared since late 1990s, and the first 40-storey complex (Toa Payoh Towers) was completed in early 2005 (source).

The demand for new flats felt sharply after 1997 Asian Crisis. 2003 SARS outbreak and low immigration rate in early 2000s also slowed down the demand for flats. This happened right after the most prosperous decade, with 24,000-36,000 flats completed each year between 1994 and 2001. The queue, once 5 years long, vanished and left about 40,000 unsold completed flats in the year 2000, most of them being 5-Room and Executive.

HDB made a surprise decision in 1995 to close the registration queue for Executive flats, shortly after introduction of Executive Condominiums. Last EM was completed in 1998 and last EA in 2003, for people in the queue. Supply of 5-Room flats was also reduced and very few were completed in 2007-2009. A common misconception is that Executive Apartments were replaced by Executive Condos. Wrong, Executive Condos include flats in variety of sizes from 50 to 300+ sqm.

The Registration for Flat (queue selling system) was suspended in 2002 due to unsold flats. It was a good selling scheme because everyone was getting a flat, not just lucky ones like in BTO.

Walk In Selection has been introduced in March 2002 allowing people to book unsold flats anytime. It ended in February 2007 and was replaced by balloting exercises named Quarter-Yearly Sale of 2/3-Room flats and Half-Yearly Sale of 4-Room and bigger flats, which in 2010 were combined in Sale of Balance Flats, which sell leftover flats from past BTO and SERS projects, plus old flats repurchased by HDB. Because some flats are completed and you can collect keys immediately after balloting, so many people apply for SBF and in towns with low number of flats 100+ people battle for one flat.

Build-To-Order was introduced in April 2001 and became main supply of flats. Flats are offered for sale before being built. Tender for construction is called only if at least 70% of units have been booked (50% since 2011), otherwise the project is canceled and may be re-launched when will be more demand, with a different name and sometimes different design. The first projects enjoyed low interest, 5 of them being cancelled, but once Walk in Selection ended, BTO projects became oversubscribed, and since 2008 HDB launch 2 BTO projects every month. See list of BTO launches.

BTO system allow you to choose exact location of your home and you know when it will be completed, but when number of applicants exceed number of flats available, only lucky people are invited to book a flat, many people need to apply multiple times until get a good queue number.

BTO system prevent HDB to built surplus of units, but it created a lag in housing supply. HDB increased BTO supply from 9,000 flats in 2009 to 25,000 flats in 2011 but this was too late. Since Walk-in Selection ended in 2007, people who are eligible for new flats but do not accept the 3-4 year waiting time of BTO system, or fail at balloting, go to resale market, plus low number of flats completed in 2002-2010 decreased supply of resale flats, consequently resale flat prices doubled from 2007 to 2012 and the prices of new flats grew according to resale prices.

Design, Build and Sell Scheme is public housing built by private developers and sold by agents, their architectural design is similar with condos, but lack condo facilities such as guards, gym, pool, tennis courts, etc. First DBSS project was launched in 2006 and completed in 2009. DBSS land sales were suspended in July 2011 after the Sim Lian Group, developer of Centrale 8 (8th DBSS) set outrageous prices up to $880,000 for 5-Room. 13 land parcels were sold to private developers who built 8650 DBSS apartments. See list of DBSS projects.

Punggol 21 was announced in 1996 and got first residents in 2000 or 2001, a modern waterfront town featuring a mix of high-end HDB and Executive Condos, it is the first HDB town where each precint is individually designed and feature integrated carparks with green roofs, and no corridor-facing units. 1997 Asian Crisis and 2003 SARS turned Punggol into a ghost town with many unsold flats and no amenities. As 31 March 2004 it had 3768 4-Room, 10031 5-Room, 1126 Executive units, then construction was very slow until 2010. The Punggol LRT Line, despite having both loops completed in 2004, east loop opened in 2005 while the west loop opened only in 2014.

Pungool 21+ was announced in 2007 to rejuvenate the town, involving building a waterway through undeveloped part of town, amenities and low-end BTO projects with 2/3/4-room units. Imagine that if there was no 1997 Asian Crisis, Punggol was developed with big flats but without waterway!

2000s random HDB floor plans

Along 4-Room (90 sqm) and 5-Room (110 sqm), HDB reintroduced 3-Room (60 sqm, later 65 sqm) and 2-Room (35/45 sqm).

First 3 Room were in Cantonment Towers (SERS replacement block completed in 2000, lease 2002) and Clementi 366-367 (blocks with 1/2/3-Room flats completed in 2001, lease 2003). Special mention to Yishun 849 (weird block with completion year 2002 and lease date 01 Jul 1999 according HDB website).

Officially 3-Room was introduced in mainstream supply in Fernvale Grove (August 2004 BTO, completed in 2007-2008) and 2-Room in Fernvale Vista (July 2006 BTO, completed in 2010).

Studio Apartments (35/45 sqm) were introduced in 1998 (first 6 Studio blocks were completed in 2001), they are restricted to elderly (55+ years old), 30-year leases and cannot be sold in resale market. Originally were built in all-studio blocks, but in 2005 Eunos Court was completed with Studio mixed with normal flats.

The average size of new flats dropped from 105 sqm in 2000-2005 to 90 sqm in 2007 and around 80 sqm later.

HDB resumed building rental blocks in 2007, completing in 2009 first new corridor-style blocks with 1/2-room apartments, for people who are unable to own a flat.

2000s projects feature unique designs, although similar circular pattern: living – common bedrooms – master bedroom – bathrooms – kitchen, but with a lot of variations in room sizes and windows, there are variations even from one floor to another floor of same block, so I cannot post on my website all possible floor plans.

2000s flats offer full privacy (except rental blocks). Flats with rooms facing to corridor were built in small numbers until 2004 lease year. First BTO project was completed in 2004 and got lease from 2006, so all BTOs offer full privacy. Compared with 1990s flats, the layouts were improved, bedrooms were downsized in favor of larger living room, the study area returned in 5-room flats, and common toilet entrance is no longer in kitchen.

Typical floor from 2000s: Studio (35 / 45 sqm), 3-Room (65 sqm), 4-room (90 sqm), from Eunos Court and Kallang Heights SERS projects. BTO projects use similar layouts
SA (35 sqm) SA (45 sqm) 3-Room (65 sqm) 4-Room (90 sqm)

2003-2004 Punggol floor plans: 5-Room (114 sqm) and Executive (128 sqm), oversized living room
5-Room (110 sqm) EA (128 sqm)

Pinnacle @ Duxton, the first 50-storey public housing complex, was launched in May 2004 and got first residents in December 2009, for HDB anniversary of 50 years in February 2010. It was the biggest BTO project (7 blocks × 44 residential floors × 6 units per floor = 1848 units), 2 levels of skybridges, 2 flat types (S1 4-Room 90-93 sqm and S2 5-room 103-106 sqm), different combinations of bay windows, balconies and planters create 35 distinct flat layouts.

Nice find! http://www.msaudcolumbia.org/summer/?p=3032 – full complex floor plan and elevations.

2010s – Today trends

Three new housing areas were announced in HDB Press Release in 2013: Bidadari Estate (within Toa Payoh planning area), Tampines North and Punggol Matilda. Additional construction is done in Bukit Batok (west end), Choa Chu Kang (south end), Yishun (east side) and Sembawang (south area towards Yishun). The planning work for Bidadari started in 2012 and got first BTO launches in 2015.

Timothy wrote in 2011 on Wikipedia that after the current New Towns will be saturated, HDB will start building flats in Tengah, Simpang, Bukit Brown, Bidadari and Seletar… looks like a personal guess rather than official info.

Tengah, the 24th New Town, was officially announced in 2016 and first BTO was launched in Nov 2018.

2010s flats

SkyVille & SkyTerrace @ Dawson, two iconic BTO projects broke record of most expensive HDB flats, due to prime location near Queenstown MRT, and were still oversubscribed (9865 applications for all 1718 units, up to 12 applicants for each 5-rm unit, but in case of 3-rm units were slightly less applicants than units). Flats are even smaller than in [email protected], to 83 sqm for 4-rm and 101 sqm for 5-rm. SkyTerrace feature lofts and paired units (similar with dual-key units in condos), caused waste of space in already too small apartments.

Other BTO projects of 2010s decade remained at the standard sizes 45 / 65 / 90 / 110 sqm (internal floor area, in resale transactions they will appear 2-6 sqm bigger due to A/C ledge and balcony). Supply of 5-room was increased, average flat size rose from 80 sqm for BTO flats launched in 2009 to 85 sqm in 2012, then dropped to 75 sqm in 2014 due to increased supply of 2-room flats once singles over 35 were allowed to purchase new HDB 2-room flats.

Meantime, private developers downsized apartments, affecting DBSS and EC projects too, for example Trivelis sizes are 60 / 80-82 / 105 sqm. Of the 105 sqm 5-room, only 88 sqm is internal, be shocked at floor plan! If they specify balcony size 12 sqm, living room should be 3×5 m, common bedrooms 3×2.5 m, study 2x2m.

HDB do not reintroduce Executive Apartments, motivating that these flats were purchased by rich families who can afford too much space for no reason, also the average household size dropped thus larger flats are no longer necessary. Instead, HDB introduced 3gen flats in July 2013 BTO and restricted them to a married couple plus another family relative. 3gen flats have 4 bedrooms and 3 bathrooms in 115 sqm (following a trend started by Executive Condominiums that introduced 5-bedroom flats).

2-Room Flexi was announced on 19 August 2015, they replace Studio Apartments and 2-Room, can be purchased both by elderly (15-45 years lease, no resale market) and by families and singles (99 years leases, can be sold on resale market).

More USEFUL info

What is HDB ceiling height

HDB floor-to-floor standard is 2.80 meters, ceiling height is 2.60 m except top floor in some 1990s blocks which is 2.90 m, I need confirmation if in other decades the top floor have taller ceiling than 2.60 m standard.

How to find the age of a HDB block

HDB do not provide exact year of construction, except in press release about the blocks that are selected for SERS.

HDB provide instead the Lease commence date in Resale Flat Prices e-service for blocks available on resale market (no blocks under MOP or rental blocks). In Singapore the lease commence date is more important than building year. Lease year correspond with building year + 1, with few exceptions.

See also Enquire status of HDB upgrading programmes e-service, showing number of units in any block, too bad that they do not display the year of construction, as selection for upgrading programmes is based on construction year.

I compiled myself the Database of HDB blocks in Excel format with all above information and sell it to companies while ordinary people can use HDB Map to information about any block (lease commence date, number of units, flat types, etc).

How urban planning in Singapore was done

Since 1960 to 1990s all HDB towns were planned using a standard density of 200 dwelling units per hectare. Flat sizes were growing over the years, leading to a stupid situation: the blocks with big flats and wealthy residents were denser and their occupants did not had enough space to park their cars, while the 1-room rental flats had largest open spaces and empty carparks.

Somewhere in 1990s a new urban planning control was introduced: plot ratios (gross floor area divided by land area). To create a vibrant city, low-, medium and high-density areas were created. The ratios were revised and raised in Master Plan 1998, today most public housing are in 2.8 – 4.2 range, low-density condos are low as 1.4 and office buildings in Central Business District reach a plot ratio of 12.

How many New Towns built HDB in Singapore

Based on construction stages:

  • Singapore Improvement Trust (SIT) and Housing and Development Board (HDB) built 20 New Towns (10,000-70,000 units) and about 80-100 small estates (under 10,000 units).
  • Economic Development Board (EDB) built in 1964-1968 and Jurong Town Corporation (JTC) built between 1968 and late 1970s 5 estates in Jurong and Sembawang industrial areas.
  • Housing and Urban Development Company (HUDC) built between 1974 and 1987 22 estates totaling about 9,800 units, sandwich housing for middle-income people who did not qualify for HDB flats but could not afford a private property. List of HUDC estates.

HDB took over JTC and HUDC in 1982, becoming sole provider of public housing in Singapore. The last 12 HUDC estates were actually built by HDB.

The HDB Annual Reports up to 1989 display a list of about 100 estates.

Based on current town boundaries:

URA defined 55 Planning Areas in 1991, HDB New Towns and Estates were reorganized into 20 “Towns” and 11 “Other Estates” in AR 1990, few years later the other estates were regrouped into 6, of which Sembawang and Sengkang were turned into “towns” in AR 1996, Punggol was added in AR 1999, Lim Chu Kang was demolished, reaching today figure of 23 towns and 3 estates. Tengah was announced in 2016 as 24th HDB Town. There is no relation between Planning Areas / Towns and historical development HDB New Towns / Estates.

The current 24 HDB Towns and 3 Estates match URA planning areas with 2 exceptions:

  • Kallang-Whampoa is one HDB town stretching on 3 planning areas (Kallang, Whampoa, Novena).
  • Pasir Ris town also include Changi Village (from Changi planning area).

More notes:

  • Geylang, Kallang-Whampoa and Bukit Merah towns contains several HDB estates built inside original Singapore city so are not “new towns” but Annual Report classify them as “town”.
  • Central Area, Bukit Timah and Marine Parade appear in Annual Report under “other estates” and in HDB Resale Flat Prices e-service as “town”.
  • Lim Chu Kang estate is no longer in use since 2001, but it appeared in HDB Resale Flat Prices e-service until 2009.
  • Tengah was added in HDB Resale Flat Prices e-service in 2016, despite that first BTO was launched in November 2018 and only around 2026 the flats are expected to reach resale market.


About me

I wrote this article from my personal research since 2009, because others (including Wikipedia) are incomplete, not detailed, create confusion and may contain errors. Please do not copy any part of page TEXT without my approval. Photographs are from Panoramio, Wikipedia, etc and are linked to their original source. Feel free to use the HDB floor plans, for using photographs you may want to ask permission to their original authors.

How I got floor plans?

During 2009 research, I picked 52 floor plans from October 2009 Sale of Balance Flats, copying images from PDF brochures (one PDF per town, few hundred floor plans to choose from). They had cream background, about 400-600 pixels tall, 29 pixels per meter. Additional floor plans I collected from random forums and blogs, reaching 100 floor plans in 2012 that represent 90% of all HDB flat types built before BTO era. Images were resized with HTML code “height=200px” so anyone accessing the page, had to download 20 MB of full-size images, causing excessive server load.

In 2014, to reduce bandwidth usage and improve website design, I re-made the floor plans using March 2012 Sale of Balance Flats (1000+ floor plans to choose from, each on a separate PDF file, took me about 20 hours to download all PDFs). I took screenshot of PDF file at 100% zoom, cropped image in Paint then added the gray info bar at bottom. Full-size images about 600-1000 pixels tall (44 pixels per meter), and thumbnail images at 1/4 size. Page size reduced to 8 MB. See comparison: OLD vs NEW floor plans.

The floor plans shown here are far away from being “complete”

This page was intended as educational material, showing HDB history and evolution of typical floor plans, but the audience is mostly resale flat buyers than students, they believe that this is / they want this to be a complete collection HDB floor plans, no matter how many floor plans I post, they want more!

Lots of variations exists. Example: 3-Room New Generation flat (67 sqm), the units that are not next to staircase do not have that thick wall, units that are not next to corridor-end unit do not display a second door on corridor, all these 4 can be mirrored, total 8 possible floor plans. I can post over 1000 floor plan variations, and no one will know how many other variations exists. This would overload website and will create trouble for people trying to find a basic floor plan.

Occasionally I get emails from “contributors” sending me their own floor plan (in most cases, too similar with one posted already, or too rare to worth posting), other people complain that the website is cluttered. This is why I decided in late 2012 to STOP adding more content unless there is something special.

I may delete least clicked images to improve usefulness of website. See most downloaded HDB floor plans (April-July 2014).

Buy my collection of floor plans

I downloaded from HDB website over 10,000 files from Sale of Balance Flats between 2008 and 2016: individual flat plans in PDF (they include unit number), whole block plans in PDF, site plans in JPG, etc. I can provide my collection for a price. Do note that this is complete collection of the flats sold at SBF, not complete collection of all HDB flats ever built, and there are many duplicate floor plans.

Trouble finding floor plan of a certain block? Have a floor plan but do not know where it is located?

I have high experience in HDB architecture so I can identify flat types in 99% of HDB blocks just by looking in satellite photos, eventually Google street view, and in the past I helped numerous people by indicating possible floor plans (if I have them), but as website traffic increased, it became annoying.

Since 2017 I made HDB Map where you can click any block and see typical floor plans for each block (for standard blocks built up to 2005, and PDF brochures for BTO blocks). If clicking your block on map, it do not show floor plans, DO NOT message me asking for floor plans, most likely I don’t have any from that block. There may be 10-20% chances to have a floor plan in my computer and when I will have more free time I will look through floor plans and add on map.

If you want individual unit floor plans for recent BTO blocks, do a Google image search for precinct name (rather than block number), or look on www.renotalk.com and other forums where people post their floor plans asking for renovation ideas. I do not have in my computer more than what can see yourself in forums.

Note: floor plans posted in this article, on HDB Map or emailed by me should be used to get a rough idea of flat layouts available in a particular block, you should not give me full unit address because I CANNOT guarantee giving you a floor plan that is 100% matching YOUR unit. As explained above, there are 8 possible variations of 3-Room New Generation flat (67 sqm), in a single block.

If you already purchased a flat and need CORRECT floor plan for renovation, you are advised to buy from HDB for $5.

If you have a floor plan and don’t know where it is located, send it to me and I can also help you.

Map made using Google Fusion Tables, a FREE experimental application which I discovered in September 2017, it provided only 9 colors of colored dots, as well as other icons representing various businesses. Google announced closure of Fusion Tables on 3 December 2019.

In October 2019 I moved to ZeeMaps, a paid service that provide 31 colors to choose from. If anyone thinks that is better to use different colors that indicate block types and construction years, please tell.

If you want data in Excel format for commercial use, you can buy the Condo Database.

Data is sourced from PropertyGuru, which have most comprehensive condo directory in Singapore, but a couple of condos have wrong GPS coordinates, this is why looking on map you may see condos with no clickable dot, example Rainforest and iNz Residence, their dots are 1300 meters west from correct location.

HDB floor plans > AutoCAD .DWG

I can provide DWG file, 2D or 3D model of your HDB flat for only $40!

HDB 5-Room flat Fernvale Foliage 3D ModelAnd not just HDB floor plans. I can also design condo floor plans, house plans, etc. Contact me for anything that can be drafted in AutoCAD!

I am writing this page in 2013 after being hired by a Malaysian architect to draw 5 HDB whole block floor plan in AutoCAD, for analysis of space efficiency. Later, a Singaporean asked me to draw his own HDB flat and suggest furniture layout. Another one asked if I have certain HDB flat in DWG format, I replied “I can draw it now in AutoCAD” but he said “Thanks anyway” and quit.

Beside this, watching website traffic I see many searches like “hdb 3-room new generation dwg file“, and most people do not click About Me page to see that I am also AutoCAD designer and I could offer DWG files. So I made this page to show… some of the HDB flats designed so far.

HDB floor plans AutoCAD DWG file


You can give me floor plan of your flat, you can choose a floor plan from the page with 100 typical HDB Floor Plans (but beware of possible differences between your flat and the typical floor plans posted here), or give me your block number and I may have or not the exact floor plan in my collection of PDF floor plans collected from Sale of Balance Flats.

There is not mandatory to provide a floor plan with dimensions. I can also use a block plan from BTO brochures, put it in AutoCAD, draw a polyline over 4-room flat and scale it until it reach the floor area of 90 sqm. There will be a small error margin, but it will be no problem if you use DWG file for presentation only and not for calculation of interior design.

You can choose the detail level (2D or 3D, add furniture, dimensions, or leave only walls) and how to give you (DWG, DXF, PDF, etc).

Price formula: $20 + $20 for each flat floor plan or + $40 for each block floor plan. This formula is intended to provide discount for people who need more than one floor plan. With other words, $40 for first flat and $20 for additional ones, $60 for first block and $40 for additional ones.

Drafting 2D over HDB floor plan takes about 1 hour if I am not busy with another project. 3D-ing a 2D plan takes 10 minutes.

I treat each customer individually and give you a personalized DWG file. There is a chance that you want DWG of same flat type as a previous customer, this save some time, but the drawing may have only walls in 2D and 3D because this is what the previous customer wanted, while you want 2D only but with dimensions and furniture, so I cannot sell “as it is”, instead I will remake drawing “as you want”.

Possible upcoming BTO locations

Many people come there from google searches like “2020 BTO list” or “BTO launch location 2020“, as well as asking me such things over chat, also asking project name and prices.

You can see Upcoming Sales Launch on HDB InfoWeb. 6 months ahead we can see next BTO location and flat types available. Project name, prices and the exact day of launch are not known until the BTO is actually launched.

Every town with empty land parcels may have BTO projects, use the map on homepage www.teoalida.com to spot empty parcels. We don’t know how soon a land parcel will be developed as BTO, some parcels can be sold to private developers instead.

Mature towns can get BTO flats too, on the land cleared via SERS. Example: Ang Mo Kio blk 247-252, Clementi blk 401-409, Sims Lane blk 54-60, or Kallang-Whampoa lands resulted from demolition of industrial areas.

HDB announced on 29 August 2013 the Public Exhibition on New Housing Areas: Bidadari (estate within Toa Payoh town, first BTO early 2015), Tampines North (first BTO late 2014), Punggol Matilda (first BTO Sep 2013). Tengah New Town was announced in 2016 and got first BTO launch in 2018. Next new towns to be announced in coming years may be Seletar and Simpang.

Flat supply for next year is announced every December. 2017 supply as announced in Dec 2016, will be 17000 BTO flats. This is a very low supply which contradict with a news from 2013: 700000 new homes by 2030.

Advice: if you applied for a BTO and a good queue number, don’t apply via SBF hoping to get a better flat in better location and available sooner, the battle for each flat in SBF in mature towns is huge and you risk to remain homeless! Well, you can apply via SBF in Sembawang where application rate hardly reach 1:1.


As end of 2018, 220550 flats were launched in 312 BTO projects (of which 2709 flats were cancelled in 5 BTO projects). The estimated average BTO flat size is 81.60 sqm and is dropping due to raising supply of 2-room flats since 2013 (for comparison: HDB flats built in 1990s were 120 sqm in average, see this chart). Estimation was done using the standard internal floor areas:

Studio (35 sqm) x 4591 units
Studio (45 sqm) x 5038 units
2-Room (35 sqm) x 6694 units
2-Room (45 sqm) x 21802 units
3-Room (65 sqm) x 33205 units
4-Room (90 sqm) x 109323 units
5-Room (110 sqm) x 38323 units
3gen (115 sqm) x 1574 units

Real floor area shown in HDB Resale Transactions will be bigger because it will include A/C ledge (2-3 sqm) and balcony (3-4 sqm) if available. Pinnacle @ Duxton, SkyVille and SkyTerrace @ Dawson BTO flats are smaller than the standard flat sizes.

Several people asked me if I can add block numbers in List of BTO projects. I CAN do this, but will take too much effort for a list intended to be given for FREE. Other people asked me if I can provide similar list for projects built in 1997-2005 before introduction of BTO scheme, as well as projects sold via other means (SERS replacement flats, Sale of Balance Flats, etc). I CAN, and did this experiment.

On 28 September 2019 I put list of BTO for sale at $1 instead of $0. Reason: to prevent people purchasing themselves just because is $0 and not because they need such data (I still give to FREE but you need to contact me if you are REALLY interested), my initial strategy was to offer a couple of small databases for free hoping that will encourage people to pay for BIG databases afterwards, but it turned to have opposite effect: people probably disappointed by small amount of data included in free databases, went away and never purchased any paid database afterwards, while the ones who purchased paid databases, they did this directly without testing with a free one first.

Depending by how many people download $1 list of BTO projects now, I will decide to spend or not spend extra effort expanding the list with block numbers and add non-BTO projects. If I expand the list, its price will be $20.

Source of data

2001-2009: Wikipedia’s BTO article, it had a list of BTO projects (now deleted, because it had too much info for such a general encyclopedia), initially I used it to compile the above List of BTO in 2011.

2010-present: the brochures issued by HDB at every new launch. I saved all brochures and offer them for free download on my website too, see BTO brochures.

Later I found that Wikipedia was full of mistakes. One visitor reported that Spring Lodge was not cancelled. I checked the map and he is RIGHT, Wikipedia was WRONG, showing Spring Lodge as block 465 cancelled, with completion date 2007, Spring Lodge has been built, BUT as block 466 (lease commence date 2006, completion probably 2005). WTF!!?? River Edge supposedly completed in 2005 seems that was the one cancelled? In case Wikipedia shows Spring Lodge under name River Edge, does anyone know which BTO has been cancelled in 2003?

Few more mistakes reported by visitors, mostly regarding typo in number of units, have been corrected. Please report any more mistakes!

Note about completion date

Many people asked me if a BTO can be completed earlier. YES, the estimated completion acts like a deadline, in most cases residents collect keys up to 3-6 months earlier. Note that Pinnacle @ Duxton residents collected keys and moved in Dec 2009, but work continued at skybridges until May 2010 scheduled completion date.

Originally I took completion dates from Wikipedia which specify same month 4 years ahead, and I kept adding 4 years of the projects not listed in Wikipedia, but I realized THAT WAS WRONG as most 2009-2010 BTO are completed in 3-3.5 years (6-12 months faster) because HDB decided in 2010 to speed up BTO production, affecting the already-launched projects. In 2011 I have corrected the completion date for the post-2009 BTO, now specifying the “Estimated completion date” shown in sale brochures provided at BTO launch date.

Occasionally HDB show a different, updated completion date when unsold flats are re-launched in SBF, earlier than completion date estimated at the BTO original launch, but since not all BTO have unsold flats, and to prevent being blamed for providing WRONG completion date by people looking in original BTO brochures, I choose to show the original estimated completion date.

Under construction BTO have communities on Facebook and on various forums, residents posting construction updates and predict completion date. Check them!

Some people ask me what is the ACTUAL completion date or key collection date of completed BTO, I cannot answer, you should ask someone residing in that BTO, or check HDB Events Calendar, look for Welcome Party / Completion Ceremony.

Lease commence date is about 1 year after estimated completion date. Minimum occupation period is 5 years starting from key collection date, which vary from flat to flat. If you want to estimate when first flats from certain BTO will be available in resale market, you should add 4½ years to estimated completion date from above table.

Non-BTO projects

Build-To-Order scheme introduced in 2001 became main supply of HDB flats, at same time precint names became standard for all new HDB developments (precint names were also added for older blocks during upgrading programmes, also added at an unknown date for all blocks in Sengkang including the ones built before introduction of BTO scheme).

But such precint names were used for other schemes too, such as SERS replacement blocks. Numerous people thinks that any group of HDB blocks that have a name is a BTO, and when a Sale of Balance Flats is done, they asked me info about “these BTO which are not found in your list of BTO projects” or blamed me for having an incomplete list of BTO launches.

The above list is the complete list of projects sold via BTO scheme, however HDB does build other flats which are NOT offered for sale via BTO scheme:

List of DBSS projects – blocks built and sold by private developers, but managed by HDB like public housing.

List of SERS sites – blocks built for replacement when old blocks are selected for redevelopment, their surplus flats are sold via SBF in same manner with unsold flats from BTO projects. There have been 2 projects (Sri Geylang Serai and Ping Yi Greens) which were built for SERS and also offered for sale via BTO.

There are also projects which are neither BTO, DBSS or SERS, they are build in advance and flats are sold via SBF: Buangkok Court, Fernvale Lodge, Golden Peony (Tampines), Jurong East Court, Jurong East Vista, Marsiling Heights, Tampines Lodge, Tampines Ria. Tell me if you know any more!

(sample floor plans)

Important: flat type naming represent approximate size in sqm and number of rooms, NOT the floor plan layout. Do not associate each flat type name with the sample floor plan shown here.
Many different floor plan layouts exists with same name of flat type. See HDB floor plans page for more floor plans!

I saw a list of HDB flat types & models on SingaporeWatch.org as well as many other blogs, I have no idea who copied it and who was the original author or it, but since it was wrong and incomplete, I came with idea to make my OWN list of flat types in 2011 rather than copying it in my website too. At www.teoalida.com I am the original author of the above list. Please do not copy it without my approval!

Block types
Slab block – long narrow corridor-style block with 4 to 40+ units per floor
Point block – 4 apartments per floor, no corridors, being placed at distance from other blocks
Atrium block – a term introduced in 1990s denoting blocks with more than 4 units per floor but without long corridors
All 3 terms are no longer in use since late 1990s.

HDB blocks built after 2000s are a mixture, point/atrium blocks having 4 to 12+ units per floor, long corridors but without rooms facing to corridors, and the blocks are placed close each other so they looks like a slab block when viewed from street.

Frequently asked questions

What is the difference between Studio and 2-Room
Floor plan is similar, BUT…
Studio are restricted to age 55+, sold with 30-year leases, with built-in kitchen cabinets, wardrobe, elderly-friendly features, cannot be sold in open market.
2-Room can be purchased by anyone, sold with 99-year leases, with bare rooms. 2-Room can be purchased by singles too since July 2013.

Studio Apartment and 2-Room were replaced by 2-Room Flexi in 2015 that can be sold with either 99-year lease for anyone, either short lease (15, 20, 25, 30, 35, 40, 45-year) to elderly.

What is the difference between 4-Room and 5-Room
The difference is 20 sqm, where these 20 sqm are added vary much, larger living room including study corner, larger bedrooms, or in few cases, an extra bedroom!

What is the difference between Standard and Premium HDB flats
Premium contract: tiles, wall paint, doors, kitchen cabinets, probably wardrobes too (not sure), plus better outdoor landscape, and in best cases, basement carpark. Most premium flats have full-height windows, but this is not a rule.
Standard contract: raw concrete waiting for your renovation, doors optional.
Since late 2000s premium flats are offered only in good locations, near MRT or near waterfront.

What is the difference between BTO and DBSS flats
BTO are sold by HDB at subsidized prices while DBSS are sold by profit-hungry private developers at super fucking crazy outrageous high prices.
Beside this, DBSS imitate condos including their bad features, such as smaller rooms but big balcony and A/C ledge, they have NO advantage over BTO flats.
DBSS flats are supposedly higher quality than BTO premium flats, but recent DBSS projects proved otherwise, residents were upset about quality in Trivelis, Centrale 8, and Pasir Ris One.

Beware of HDB naming system!

The naming system (4-Room, 5-Room, etc) is confusing, it do not denotes actual number of rooms, it define the flat size in square meters. The total flat floor area is (too) standardized after 1998, probably for pricing reasons. Individual room sizes may vary very much, for example: in 1985-2000 period, some 4-Room Model A had 3 small bedrooms and a living room big enough to build a 5th room (example), while some 5-Room Improved from same period had only 3 (but big) bedrooms and a living room (example).

Before 1988, all 5-Room and Executives had 3 bedrooms and a large room with separate living and dining areas, Executive had an additional utility/maid room.

From 1988 to 2000, all 5-Room and Executives had 4 bedrooms or 3 bedrooms + study, but Executives had larger living room, sometimes separate living and dining areas.

After 2000, the 5-Room are nothing else than 3 bedroom flats with larger livingroom, while Executive Apartments have 3 bedrooms plus an open study area. Since Executive Apartments were phased out in 2005, the study area was reintroduced in 5-room flats.

My opinion: too much standardization in flat sizes, the naming system (Improved, Model A) should be dropped from resale transactions or replaced with a new name, because since 1998, ALL 4-Room are Model A and all 5-Room are Improved. This creates confusion with the 1970s Improved and 1980s Model A flats, also the today 5-Room flats are nothing else than a larger 4-Room, being the smallest flats named 5-Room in HDB history.

List of SERS sites

Outram Park DemolitionBetween 1995 and 2007, 71 SERS sites were announced. Between 2008 and 2018, only 10 SERS sites were announced, total 7883 flats. At this rate, 306 years are required to replace all 241343 flats built between 1971 and 1980. It is obvious that SERS is highly selective and only a small amount of these flats will be selected for redevelopment.

SERS history

During 1990s, the old estates built in 1960s and 1970s suffered from dilapidated buildings, aging population and businesses moving out. On resale market Queenstown and Ang Mo Kio were cheaper than Pasir Ris, one of the cheapest towns today (source: Resale flat prices database). To counter this, HDB launched Main Upgrading Programme in 1990, Interim Upgrading Programme in 1993 and Selective En-bloc Redevelopment Scheme in 1995.

Some of the owner-occupied blocks built up to 1980 are selected for SERS residents are rehoused in new blocks built in nearby location, to maintain community. Usually low-rise blocks with large spaces between them are selected for SERS while dense and tall blocks are selected for upgrading.

HDB do not give you a replacement flat automatically, instead they compensate you with the market value of your flat, then you need to buy yourself another flat, which can be bigger or smaller, and you can get profit or need to pay with CPF the difference to the price of new flat. I would like to know how people dealt in early SERS sites, where affected blocks had 2/3-room flats and replacement blocks 4/5-room flats sold at much higher price. Since 2004 the residents can enjoy SERS benefits anywhere instead of being limited to the designated replacement blocks.

Although small-scale redevelopment of old estates started in 1966, with demolition of single-storey artisans quarters, the mass demolition of rental blocks started in late 1980s.

Some owner-occupied blocks may have been also demolished before SERS being introduced. With no dedicated replacement blocks, residents were compensated at market value and moved anywhere they wanted. For example Dawson estate had over 100 blocks but only 3 of them (blk 6A, 6B, 39) appears in the list of SERS sites. I am in doubt that all others were rental. At least terraced houses were owned.

HDB resale flat prices per square meter by lease year

The 1997 Asian Crisis affected demand for flats, resale flat prices in young towns continued to drop by 2006, while in mature towns prices started to rise in 2002 fueled by upgrading programmes and SERS.

Between 1995 and 2007, 72 SERS sites were announced. This created widespread rumors among population that any 1960s and 1970s block can get SERS, increasing demand for old flats, people buying 1960s and 1970s flats on purpose to have their block demolished and receive a new flat at subsidized price. As seen in above chart, blocks leased in 1966-1980 are priced higher than blocks leased in 1981-2000. Due to this reason, is no longer viable for HDB to redevelop old blocks, number of new SERS sites announced dropped dramatically.

Between 2008 and 2018, only 10 SERS sites were announced, total 7883 flats. At this rate, 306 years are required to replace all 241343 flats built between 1971 and 1980. It is obvious that SERS is highly selective and only a small amount of these flats will be selected for redevelopment in the near future, making impossible to predict which blocks will be next SERS site.

I believed that HDB is waiting for the old flats to get closer to their end of lease when their market value will drop significantly, then increase number of SERS sites.

On 19 August 2018 HDB announced that only 5% of total sold flats are eligible for SERS, of which 4% have been selected already. For all other flats there will be VERS (Voluntary En-bloc Redevelopment Scheme) that will start in approximately 20 years from now (probably in 2036 when first leases reach 70 years old). Polls will be made in each precint and they require 75% of owners to vote to go VERS or keep living in their flats until leases run out.

Due to rapid and short development of towns like Ang Mo Kio (1976-1982), Bedok (1974-1986), Marine Parade (1975-1978), HDB cannot VERS all blocks once they are 70 years old, so they will be redeveloped stages when they are between 70 and 90 years old. Details such as selection criteria, compensation offered, etc, and how VERS will be financed, are not yet decided, leading to speculation. Many things can change in 20 years, including our ruling party!

Interesting facts

Depot Road Estate built in early 1970s was fully redeveloped starting from 2000 except the 25-storey 5-room point blocks. HDB Press Release says this: Blocks 113 and 114 have not been included for SERS. These two point blocks are 25-storeys high with a total of 192 units of 5-room sold flats. Given their existing height, it is more viable to upgrade these blocks than to redevelop them. Hence they have been scheduled for the Main Upgrading Programme by the year 2000, in tandem with the redevelopment works in Phase II.

Hillview Estate built in 1977-1978 was the biggest SERS site and most controversial. Originally only the low-rise blocks were scheduled for demolition, but would left three 25-storey blocks in middle of nowhere so they decided to demolish entire estate, being the first 5-room point blocks blocks to be demolished, in 2006.

Note: blk 3, 4, 5 at Syed Alwi Road were first 25-storey blocks demolished (4-room) other 25-storey blocks demolished later are blk 110, 111, 112 Bukit Merah View (4-room) and blk 22, 23 Holland Drive (5-room).

I heard 3 different stories about reason of demolition. Political stories: opposition ward at elections, so HDB decided to mix the residents in Bukit Batok. Paranormal stories: estate was haunted by ghosts and Pontianak. Army stories: nearby camp had to be upgraded to high security camp and the 25-storey blocks allowed espionage (however the army camp can be viewed also from Bukit Panjang 30-storey blocks).

Shortest-living HDB blocks were Bedok South Avenue blk 9, 10, 11, 1-room rental blocks built in mid-1970s, demolished around 1990.

How to identify future potential SERS sites

  • SERS sites appear where height restrictions allow redevelopment into 30+ storey blocks. Geylang, Hougang, Tampines, etc, are limited to 20 floors or less, so cannot get SERS until Paya Lebar airbase will be closed in 2030.
  • So far only blocks built up to 1980 are selected for SERS, whenever rule will change and how soon, we don’t know.
  • Look in HDB Map for lease year, but it is when tenants were allowed to buy flats and does not always mean built year. For example Redhill Close blocks were built in 1955 and leased on 1 May 1983.
  • Look in Google Earth / Maps satellite photos for blocks with large spaces between them.
  • Look in URA Master Plan for areas with plot ratio 3.0, 3.5 or higher. Note: most HDB blocks have 2.8 plot ratio and it is revised AFTER blocks are demolished.
  • Look in Enquire status of upgrading programmes to check if the block did not had recent upgrading programmes. If HDB invested in any upgrading programme, the block will likely stay for 20+ more years. Clementi blocks 513-520 (IUP 1998, LUP 2008) may have been an one-off case.

There is NO rule to demolish blocks of given age. According Press Release of 22 August 1995Only a small number of estates/areas are likely to be considered for redevelopment under SERS. They will be the exception rather than the rule. These are old HDB estates developed at low density, or selected blocks which can be redeveloped with adjacent vacant land to give a better yield of flats

Depot Road blk 103, 110, 111 built in 1975 and Ang Mo Kio blk 309, 315, 316 built in 1977 were identified for SERS in 1995 and 1996 and demolished around 2000 (after 25 years). As 2018, NO block built after 1980 was identified for SERS, except an one-off case with Punggol Road blk 206 and 207 built 1986 next to blk 1-5 built 1978 (source) and demolished around 2006 (4-storey farmer blocks that were damaging the modern image of Sengkang New Town).

Height limit matter: blocks 210-224 built in phase II of Toa Payoh, 1975-1978, having large space between blocks were likely to get SERS and be redeveloped in 40-50 storey blocks, while MacPherson estate built in 1960-1965, despite of being older, was selected for MUP instead of SERS because the blocks were packed close apart, and the proximity of Paya Lebar airbase height limit of 18 floors, do not allow redevelopment in higher density. The only blocks demolished in MacPherson were 1/2-room rental blocks, demolished during 1980s.

In 2010 I identified few potential SERS sites with NO upgrading programmes, but most of them were meantime selected for LUP (except Toa Payoh blocks 210-224, Tiong Bahru post-war blocks) while only Bukit Merah View, Clementi Avenue 5 were selected for SERS, proving how HARD is to predict correctly.

In 2011 Redhill and Boon Lay sites had the first upgraded blocks to be identified for SERS, both not technically feasible for Lift Upgrading Programme). LUP began in 2001 and is scheduled to end in 2014. However, some blocks received lifts stopping at every floor during MUP in 1990s, so they do not need also LUP, making predictions HARDER. But, any block that still do not have lifts that stop at every floor is very likely to get SERS. Anyone who spot such blocks is invited to leave a comment!

Surprisingly, the Toa Payoh blocks 210-224 were selected for LUP in 2011, NRP in 2013 and HIP in 2012 and 2014. Why these blocks were apparently reserved for SERS then suddenly HDB done 3 upgrading programmes in 3 years, is a big mystery. Does anyone know what was PAP support ratio in this precint?

Potential SERS sites spotted by me + non-SERS sites that people asked about

Future SERS sites is a HDB top secret information, only few employees knowing about this, to prevent price speculation, and they are subject to change. If there are rumors that a block will get SERS, people will value their flats higher and HDB will need to pay higher compensations.


  • Nobody can answer WHEN a block will get SERS. Don’t ask such questions!
  • We cannot be sure that a block will be demolished except when the SERS site is announced. Instead, we can be sure which blocks will be NOT selected for SERS next 10-20 years.
  • HDB e-service enquire status of upgrading programmes may have errors. In 2010 I checked all pre-1980 blocks one by one and compiled the HDB Database in Excel for purpose of seeing all blocks at once, database which I updated in 2015 checking all blocks including those checked in 2010. Marsiling Drive blk 27-29 and 33-34 showed in 2010 that got MUP in 1997 and LUP in 2004, but now as 2015 the e-service do not show the LUP but only the MUP. Google StreetView confirm the LUP done in 2004. I assume that similar errors exist. I do not have time to counter-check all blocks.
  • You are advised to check yourself Google Streetview and eventually go personally at the block and talk with residents to check possible unlisted upgrading programmes.

I listed below over 20 potential SERS sites with no upgrading programmes after 2000. If HDB continue to announce 1 SERS site every 2 years, and they may announce other sites not listed here, each of the below have less than 20% chances to get SERS next 5 years.


York Hill Estate, there are 8 rental blocks and 3 ownership blocks (8, 9, 10) which got MUP in 1994 but nothing else. But first HDB need to build enough rental replacement blocks. Someone should check how many units are empty, when majority of rental blocks gets empty, SERS may come for the owned blocks!

Jalan Batu blocks 1-14 underwent MUP in 1996 but nothing else, they sit on prime land, may get SERS soon.

Ang Mo Kio

Last SERS site: 2006, so we expect a new SERS site soon.

Blocks 207-208, 215-216 underwent MUP in 1998 including lifts that stop at every floor, but were excluded from subsequent upgrades affecting neighbor blocks, together with block 217 1-room rental and nearby carpark, can free a large piece of land.

Blocks 303-306, 319-321 also underwent MUP in 1998 and nothing else, there is a rental block nearby (318).

No other SERS sites are expected in Ang Mo Kio, all blocks got LUP or MUP in late 1990s or later.


Chai Chee blk 30-40 (built early 1970s) underwent MUP in 1993 but no LUP so may be a SERS site, maybe during 2020s. blk 33-34 got LUP in 2012 making entire estate unlikely to get SERS.

Bedok blk 22-30 got MUP in 1996 then nothing else.

No more SERS sites are expected in Bedok, all blocks got LUP or MUP in late 1990s or later.


Sin Ming blocks 22, 23 24 got MUP in 1995 and only block 25 got LUP in 2009, this may be a sign that other 3 blocks are reserved for a future SERS site (thanks to Low Joo Ling comment).

Bukit Batok

Starting from 2014 I have been asking by multiple people if various blocks in Bukit Batok will get SERS (example: Justin comment). Even if Bukit Batok have potential of redevelopment into 30-storey blocks, there is NO sign that SERS programme will be extended to 1980s towns in the near future, also all blocks in Bukit Batok got LUP, so I am 100% sure that will be NO SERS in Bukit Batok until at least 2030. Residents are spreading false rumors!

Bukit Merah

Tiong Bahru pre-war blocks (built 1936-1940) are under conservation and being the place of pilot home ownership scheme in 1964, they are transacted as private properties. They will NOT get SERS, but may be sold to private developers IF conservation status is removed.

Tiong Bahru post-war blocks (built 1948-1954) are not feasible for LUP due to staircase position. This is a potential SERS site but many people (including me) hope that they will be put under conservation, like the nearby pre-war blocks.

Bukit Ho Swee estate received MUP in phases in 1992, 1994, 1996, then the blocks from first 2 phases received LUP in 2006 (the 3rd MUP phase in 1996 included upgrading lifts so LUP was no longer necessary), although it does have potential of redevelopment to 40+ storey, the LUP makes SERS unlikely sooner than 2026.

Bukit Timah

Farrer Road blocks 2, 3, 4, 6, 8 got MUP in 1994 and HDB Enquire Status of upgrading programmes says clearly that no LUP was announced. However, blocks 1 and 5 got LUP in 2011-2012, making whole estate less likely for SERS in near future. But one day in distant future, whole estate may be demolished.


No more SERS sites are expected in Clementi, all blocks got LUP or MUP in late 1990s or later.

Unbelievable! Blocks 513-520 that got LUP in 2008 were announced for SERS in 2016, at just 5 years since last SERS site in Clementi in 2011.


MacPherson estate, although built in same time with Tanglin Halt, did not got any SERS to date, because of the proximity of Paya Lebar airbase which limit height to 18 floors. However, the 2013 announcement that Paya Lebar airbase will be closed, and the lack of other upgrading programmes after MUP done in 1993-1994 which included lift stopping on every floor, indicate that SERS will come in distant future. There are 5574 dwelling units in the blocks 21-83 built in 1960s (excluding blocks added in 1990s), probably will be redeveloped in 2-3 phases, starting from late 2020s.

Jurong West

Taman Jurong blk 116-122 underwent MUP in 1998 but nothing else, may get SERS during 2020s.

Boon Lay blk 207-215 underwent MUP in 1997 but nothing else, they have very big spaces between blocks thus suitable for SERS, but where the replacement blocks can be built? HDB filled all available land in Jurong West with BTO projects.


Old Airport Road Estate blk 2-32 were built in 1958, they were never sold to tenants, in 2014 was announced that they will be cleared in 2016 and 15 of 17 SIT blocks will be demolished for an “immediate redevelopment”.

Old Airport Road blk 93, 95, 97, 99 built by HDB in 1960s allowed home ownership, they got MUP in 1992 and nothing else. I believe that they may get SERS around 2017 when the rental blocks will be cleared, the replacement blocks for these 4 blocks may be built here. People informed me that carpark is being upgraded with lift, this lower SERS potential, unless they demolish blocks and keep carpark.

Marine Parade

Marine Parade is the most expensive 1960s/1970s estate, and due to this reason, SERS is not viable. I believe that HDB is waiting for the leases to be 60-70-80 years old when flat values will be lower, then do SERS. This is likely to not happen before closure of Paya Lebar airbase in 2030s, when height restriction of ~25 floors will be removed. Where can be the replacement site?


Commonwealth View and Tanglin Halt, built in early 1960s, underwent MUP in batches between 1992 and 2000, they sit on prime land with potential of 50-storey blocks so may be a good idea to do SERS in late 2010s or 2020s. But due to large number of blocks, doing SERS would take at least 2 decades and is difficult to predict which will be the first to be demolished.

Blocks 74-80 were identified for SERS in 2008. After 6 years, in 2014, the big SURPRISE happened! All remaining Tanglin Halt was identified for SERS (3538 flats).

We expect Commonwealth (3384 flats) to have same fate in 6 or more years, the replacement site may be in Tanglin Halt which will be demolished around 2021.

Mei Ling / Stirling Road blocks 151-164 got MUP in 1996-1998, blocks 167-170 underwent MUP in 1993, both nothing else after, while nearby blocks 165, 166, 168A, 171 that got MUP in 1993 too got also LUP in 2009. This may indicate that the blocks 167-170 are reserved for demolition, or they did not had lifts upgraded during MUP due to costs.

Ghim Moh and Dover all remaining blocks got MUP in 1997, 1999, 2000 and nothing else after, since Ghim Moh blocks 9-12 got SERS in 2006 and demolished in 2014-2015, we expect a new SERS site soon!

Toa Payoh

Last SERS site in Toa Payoh was 2003, so we expect a new SERS site soon.

Blocks 1-3 got MUP in 1990 then nothing else, they do not have lifts stopping at every floor, may be a SERS site soon!

Blocks 4-15 got MUP in 1994 then nothing else, don’t know if lifts stop at every floor, may be included in same SERS site.

Blocks 34, 38, 47, 51-53, 56-61, 107-128, 158-163, 168-174 … got MUP in 1993-1995 and nothing else, are also candidates for SERS but not in near future, may take 10-20 years to replace all them, nobody can tell which ones will be first.

Blocks 91-100 also got MUP in 1995 and 3 of them (91, 94, 95) got also LUP in 2006, I would not have counted them in SERS until September 2017 someone informed me that the remaining blocks do not have lifts stopping at every floor. Not being selected for LUP despite of being eligible, may indicate a future SERS site (together with rental blocks 103-106)?


One of the biggest dilemmas about SIT terraced houses in Stirling Road and Jalan Bahagia. Lots of terraced houses were demolished during 1990s but the fact that after 2000 no more were demolished may indicate that HDB is willing to preserve these two clusters of terraced houses, how long… nobody knows.

The floor area vary from original 84 sqm to over 200 sqm, if they will get SERS, HDB need to compensate owners with record sums of money, which will give owners too much profit compared with the price SERS replacement flats. Probably HDB is waiting them to be more than 70 years old when market value will drop fast. I wish to know what was the process of demolition of terraced houses in Dawson estate in late 1990s, since they are NOT included in official list of SERS sites but they were owned thus owners had to be compensated according some criteria.

Prime Minister Lee Hsien Loong said in his National Day Rally speech in 2013 that Paya Lebar Airbase will be closed, without giving a specific date, 2017 news report said that closure will be in 2030. Once airbase is closed, height restrictions will be removed and make potential SERS sites the MacPherson 1960s estate as well as large areas in Geylang and Hougang. I am questioning if the 280 meter nationwide height limit will be removed too.

While the HDB Database is an original product “Made by Teoalida”, manually compiling data from multiple sources plus personal research, the Condo Database data belongs to SingaporeExpats and PropertyGuru websites, I do not recommend using this database in making websites. Feel free to use it for research and analysis purposes. I am NOT responsible for any copyright troubles you may face if you use their data commercially, making own website, etc. Please consider the price a fee for data scraping service from website rather than author of data.

See also my Terms and conditions.

Detailed data does exist for all major condos. Most old and small private apartments do not have number of units, TOP year, etc. There may be also small developments (less than 10 units) not included at all in both SingaporeExpats and PropertyGuru condo directories.

Description – Singapore Expats & Property Guru condo database

In 2009 I started making a database of all buildings in Singapore, for my personal research, sourcing condo name from map then digging various websites for details such as number of units (imagine how much time would take!). I abandoned the work in 2011 because it required too much effort to be done voluntarily.

In 2012 I published on website a sample of that database of all buildings and also a list of major condos, waiting for feedback to see does worth continuing the project, as paid service for professional use. Took 2 years to get feedback and realize what kind of data people are looking for, I revived the database in 2014 into a database of HDB buildings only, planning to start a separate database for condos, I posted a message in List of major condos page inviting people who are interested in a complete condo directory to contact me.

The first customer to contact me for condo database came only in September 2015, he purchased the HDB Database previously. Incidentally, in August 2015 I found tools that extract data from websites automatically, so I offered him 3 options: automatic data scraping from SingaporeExpats for $150 (2809 condos), automatic data scraping from PropertyGuru for $300 (3148 condos, a bit more details for each condo, such as postal code and number of floors), or manual data building, write condo names from onemap.sg then fill up details from above websites, for $1000 (this way would make most complete database). He said that is necessary to be very complete database, agreed with automatic scraping way, even told me specifically to scrap data from PropertyGuru, but this turned impossible because website display a CAPTCHA after every 10 pages accessed by scraping application. I ended in scraping SingaporeExpats.

SingaporeExpats is not a newsy website but a simple condo directory and it is lagging in terms of updates with latest condo launches, customer complained, and one of my friends (programmer) told me that can make in Visual Basic a custom scraping application for PropertyGuru, so I made him an offer. Programmer spend 2 weeks until he found a way to deal with CAPTCHA but charged me $300 for this, customer did not replied, after a month and multiple email he said that do not want to pay extra fee (despite that he asked initially to scrap PropertyGuru).

I posted a message inviting people interested in PropertyGuru to contact me and pay 50% fee in advance. Someone paid in July 2016 and programmer made a new scraping application. I get a CAPTCHA page every 10-50 pages which I solve myself in order for scraper to continue.

PropertyGuru website was redesigned in June 2018 making scraper obsolete, I asked my programmer to make a new scraper, but this time he was getting CAPTCHA on every single page so gave up. I contacted an Indian company who provide data mining services and they made a new scraper for PropertyGuru, using in-house human power to solve captchas, and gave me data only. I told them to include every possible data from website, including condo description, nearest MRT an schools, GPS coordinates, etc, increasing Excel file size from 2.4 to 10 MB.

I will update myself database manually adding new launched condos every few months (depending by sales frequency), and once per year, ask Indian company to run scrap again all condos.

Description – Management corporation database

In August 2016 someone asked me for MCST and managing agent contact number, this info is available for FREE on www.bca.gov.sg/bcadata/MCST.xls, however he said that this Excel file is not updated and told me to scrap www.bca.gov.sg/plan_enquiry/mcst_usersearch.aspx, to get latest data, but he did not paid me. A second customer asked me to scrap same website in January 2017. Having 2 requests, i believe that more people will come so I made a scraper for BCA website.

Scraping all MCST numbers from 0001 to 5000 takes about 10 hours and it can be done anytime you need. Because most people buy this database for one-time use in telemarketing, database need to be updated at the time you are using it. Because few people asked me to update database promising to buy afterwards, but never bought it, if you request update you need to pay first and I will provide you the updated database next day!

Several people asked me if I have a database with MCST email addresses. bca.gov.sg provide phone numbers but NOT email addresses (if you know other website that provide email addresses let me know). This because email marketing is NOT efficient. If you send 100 emails is likely to have 5 people reporting you as SPAM then nobody else will receive your emails in inbox. If you really want customers, do phone calls or SMS!

Smallest condo apartments

Smallest apartment in Singapore is 24 sqm (258 sq ft), 4 units in Suites @ Guillemard. All other studio apartments are 35+ sqm and have separate bed area. This because of URA which regulate minimum apartment size. However we need regulations of minimum apartment size for each number of rooms, to prevent extremely crowded condos like in the following examples:

Alexis Condo, 1-bedroom 36 sqm, 1-bedroom+study 47 sqm, 2-bedroom 56 sqm, very crowded layout, some apartments have no view.

Tree Scape @ Telok Kurau (site dead), 1-bedroom+study 40 sqm , 2-bedroom 49 sqm, 3-bedroom 56-65 sqm, 4-bedroom 84 sqm.

Natura @ Hillview (site dead), 1-bedroom 42 sqm, 2-bedroom 48-50 sqm, 3-bedroom 59-61 sqm, bedrooms sized like in Hong Kong (2×2 m).

High Park Residences is one of the FEW condos that include dimensions in floor plan. You can see that largest apartment type (5-bedroom) is 129 sqm, approximately the size of a 5-room 3-bedroom HDB from 1980s. Common bedrooms are just 2.5 x 2.5 meters.

Biggest condo apartments

I compiled this list in 2013, checking fat condo blocks viewed on map to find biggest regular 3/4-bedroom apartment sizes. Condos having one huge penthouse all other apartments small are not included. Since 2015 SingaporeExpats no longer show unit types and their floor areas… sadly.

Arcadia Garden (1983): 3 bedrooms 322 – 347 sq m, 4 bedrooms 345 – 434 sq m, Maisonette 610 sq m, Penthouse 697 sq m.
Fontana Heights (1985): 4 bedrooms 321 – 442 sq m, Penthouse 1102 sq m.
The Claymore (1985): 3 bedrooms 249 sq m, 4 bedrooms 311 sq m, Penthouse 457 sq m.
Astrid Meadows (1990): 3 bedrooms 180 – 240 sq m, 4 bedrooms 247 – 354 sq m, Penthouse 622 sq m.
Ardmore Park (2001): 4 bedrooms 268 sq m, Penthouse 812 sq m.
Grange Residences (2004) 4+1 bedrooms 2600 – 2853 sq ft.
Dairy Farm Estate (1989): 3 bedrooms: 181 – 205 sq m, Maisonette: 148 – 217 sq m.
Hillcrest Arcadia (1980): 3 bedrooms 132 – 183 sq m, Maisonette 255 – 269 sq m, Penthouse 213 – 235 sq m.

Also: Cairnhill Crest supposedly having 7 bedroom maisonettes… while all others apartments of Singapore have max 4-5 bedrooms. I would like to see an actual floor plan…

Database of HDB blocks in Excel format

Free sample: HDB Database (full details package)

HDB Database is an original compilation “Made by Teoalida” which took over 500 hours of work. Collecting data from multiple sources, I manually entered data in one Excel table for all HDB blocks ever built in Singapore, indicating block number, street address, postal code, GPS coordinates, construction year, lease commence date, number of floors, number of units breakdown by flat type, upgrading programmes, brochures and floor plans.

From the main table, I created additional tables analyzing number of HDB residential blocks, MSCP, pavilions and miscellaneous buildings, number of units breakdown by flat type, etc, by HDB town, phase of development and building era. Watch video to see the completeness and quality of work!

The database has been purchased by several companies, including home insurance, telecommunication, door-to-door services, real estate portals, flyer distributors, as well as many people who did not told me what business field they are in.

Regular citizens who want to view data about a couple of HDB blocks, can do this for FREE on HDB Map.

About HDB Database

As a researcher of Singapore history, I created this database intending to include all public housing buildings ever build in Singapore. SIT, HDB, EDB, JTC, HUDC, residential or auxiliary, standing or demolished. But I have trouble finding data for buildings demolished before mid-1980, because oldest Singapore Street Directory that include buildings is the 1984 one.

The HDB database is optimized for on-screen visualization in Excel, visually enhanced with colors, borders and titles, but I made it to be easily used in web development or mobile apps too. Click filter box on any Address columns, Building Era or Building Type > choose (blanks) > select all rows > delete (this will remove estate header rows, schools, places of worship and other non-HDB buildings found in HDB estates) > Save as > choose CSV > import in phpMyAdmin to get SQL file, or whatever application you are using database in.

I know that most of you are interested only in residential buildings that are currently standing (excluding carparks, pavilions or demolished buildings) and may ask to buy subsets with standing residential blocks to get a discount. I prefer to NOT sell subsets with only residential buildings, because will screw up the visual borders I added to separate precints and clusters of HDB blocks. And if I would have been to sell such subsets, I would charged (for all details package) 12-14 cents/building instead of 10 to maintain prices.

Origins: it was originally a voluntary project started in 2009, for purpose of researching housing density in selected estates and use the results in designing own apartment models. Being done without any specific target, I changed my mind numerous times, making the database a MESS, each town being a separate table with different layout depending by the date each town was compiled. I abandoned in 2011 after completing 40% of Singapore because it required too much effort for a non-paid job.

I published a sample on my website for first time in 2012 to see if anyone is interested, and in 2014 I resumed working to complete remaining towns and harmonize data in a single table for whole Singapore, and launched it for sale on my website, as PAID service for professional use.

Over next years I continued to expand database with additional columns and information requested by customers, such as postal codes in June 2015 and unit numbers in 2016, town council and electoral GRC / SMC in 2017, and update it every 3 months when HDB launch new BTO flats. You can suggest your own ideas what other data to add!

HDB Database statistics

Total number of tagged HDB buildings in database: 15283 (as Nov 2019 update).
Database include also few hundred non-HDB buildings (not tagged, not included in this count).

Breakdown by building type tag:
Residential flats: 10820 standing + 1472 demolished (including blocks with shophouses and no flats).
Multi-storey carparks: 1125 standing + 4 demolished.
Pavilions: 851 standing + 7 demolished.
Houses: 114 standing.
Industrial buildings: 51 standing.
Other buildings: 681 standing + 108 demolished (commercial buildings, electrical sub-stations, etc).
Unknown buildings: 39 demolished.

Breakdown by building era tag:
1927-1960 (SIT era): 819 buildings.
1960-1981 (HDB classic era I): 3437 buildings.
1980-1992 (HDB classic era II): 3702 buildings.
1991-1998 (centralized refuse chute): 2097 buildings.
1997-2006 (household shelter): 1989 buildings.
2004-present (introduction of BTO scheme): 3228 buildings.

Number of units is available for 10,757 blocks that were existing at least as 2010, including under construction blocks launched until November 2019 BTO. Total: 1,166,857 units, averaging 108 units per block. Every year, new blocks are completed while others are demolished, keeping this figure up-to-date is difficult. 1,063,250 dwelling units are in use as 31 March 2019 according HDB Annual Report.

Data fields included and their source

  • Block numbers: complete for all HDB blocks ever built.
  • Street address: complete except some of HDB blocks demolished before 2000.
  • Postal codes: complete for all residential HDB blocks standing as 2015 (including under construction).
  • Project name: complete for all HDB blocks that have a name (BTO blocks and old blocks that received precint name at upgrading.

Source: www.onemap.sg for current buildings, hm.onemap.sg or National Archive photos for demolised buildings. Block numbers 40% done in 2009-2010, remaining 60% done in June 2014. Street address sourced from Enquire status of upgrading programmes and later HDB Map Services, 30% done in 2010, remaining 70% done in December 2014. Postal code sourced from HDB Centralized Map. Personally not interested in postal codes, but in July 2014 a customer suggested adding them, a 2nd customer asked for postal codes in May 2015, so in June 2015 I added them. HDB Centralized Map added info boxes for under construction blocks in late 2016, allowing me to add in my database too at January 2017 update.

  • Town / Estate: complete for all Singapore. Town is official zoning while Estate is my personal classification by 175 phases of construction.
  • Project code & unit numbers: available for 3596 of 15283 total buildings, or 3029 of 3235 buildings built in BTO era.

Source: site plans from BTO and SBF brochures, added in 2016 at request from one customer. I know how useful would be to have the unit number ranges for every block, but this is NOT POSSIBLE. Hong Kong does have www.centamap.com showing unit number and position. When Singapore is going to have the same? Going from block to block to check mailboxes and get unit numbers, takes more than a man’s lifetime.

  • Town Council and Electoral division (GRC / SMC): complete for all HDB blocks ever built.

Source: www.onemap.sg. I added Town Council in May 2017 at request from one customer, and electoral division in September 2017 at request from another customer.

  • GPS coordinates, latitude / longitude: complete for residential buildings.

A customer suggested me to add GPS coordinates in 2013, but I considered too hard task to write coordinates manually. In 2015 Renata who bought my database and made a script to run in Google Maps API and add coordinates, but some were off. In 2017 I met Sik Shu Wei who made a script to extract coordinates from HDB Centralized Map and I integrated them into my database using VLOOKUP.

  • Building type: complete for all HDB buildings.
  • Building era: complete for all HDB buildings.

I categorized myself the HDB buildings by type (in November 2014) and into 6 different eras (in May 2016) because someone wanted to purchase a subset with recently build blocks. Filtering by lease commence date would have been difficult, because U/C blocks or under MOP do not have a lease date. Building era is based on major changes in HDB design, such as introduction of centralized refuse chutes and lifts stopping at every floor in 1991, household shelters in 1997, BTO mode of sale in 2004. I further improved building eras in September 2017 when I made Map of HDB blocks where color of each dot indicate building age.

  • Building year: available for all buildings standing as 2018.

Source: CSV file provided by HDB. building year is available for some of the older buildings, from HDB Press Releases about SERS blocks or old newspapers seen at National Archive.

  • Demolition year: complete for all 1566 demolished buildings.

Source: estimation using old Street Directories (1984, 1988, 1991, 1993, 1995, 1998) or Google Earth satellite imagery (after 2000).

  • Lease commence date: complete for all residential blocks available on resale market (not available for blocks within MOP or rental blocks).

30% done in 2010 and remaining 70% completed in December 2014, source: HDB Resale Flat Prices, year only. Since 2015 I added month and day beside year, sourcing from HDB Centralized Map. In 2017 I added year-month-day lease commence date for all blocks thanks to Sik Shu Wei script.

  • Estimated completion date: complete for blocks under construction or under MOP.

Source: BTO brochures. When blocks fulfill MOP I replace estimated completion date with lease date. Update frequency: when new BTO are launched.

  • Number of units (text form) & upgrading programmes: complete for residential buildings standing as 2010.

Source: Enquire status of upgrading programmes for blocks completed as 2015 (25% done in 2010, remaining 75% ON HOLD waiting for a customer paying me…. been paid in May 2015 and completed in June 2015.

A customer suggested to make separate column for each upgrading programme (MUP, IUP, LUP, HIP, NRP, SLRP) and indicate announcement date and billing date. Re-compiling upgrading programmes information will take a large amount of time so I am waiting to see if there are other customers interested.

  • Number of units breakdown by flat type in separate columns: complete for all residential buildings.

Idea used since 2011 for List of BTO projects. In 2014 I planned to use idea for HDB Blocks Database too, and did the job for SAMPLE file that included Jurong West, while for rest of towns I done in June 2015, time when I added also breakdown by flat type of number of units at the time block was completed, beside current figure sourced from Enquire status of upgrading programmes. (number of units is VARYING over time due to adjoined flats).

Since 2016 I add number of units when blocks are launched rather than when completed, source: site plans from BTO / SERS / SBF brochures.

  • Number of floors, units per floor, estimated number of units: complete for 95% residential buildings.

40% done in 2009 I estimated number of floors for about 40% of blocks, by measuring shadow length in Google Earth (error margin +/- 1-2 floors). Once Google Streetview was launched in Singapore in December 2009, I accurately counted floors for 20% of blocks during 2010.

In 2014 I decided to complete database without number of floors because it was taking too much effort and I believed that it is no longer needed, precise number of units became available in HDB enquire status of upgrading programmes, no longer need to multiply floors with units per floor.

In 2015 a customer (Renata, see her comment) offered me a BONUS of $400 to complete number of floors for remaining 40% of blocks, but after doing half of job she told me to STOP THE JOB because her boss don’t want to pay.

Virtual Singapore, a very detailed 3D map, was announced in 2015 to be ready in 2017. In August 2017 it was announced that will be ready in July 2018. Virtual Singapore would have helped me counting floors easier and accurately than in Google Street View. In mid-2018 another announcement said that map will be ready in 2018 for government agencies while public access will be few years later.

Meantime Google Earth launched in August 2018 its own 3D map for central Singapore, expanding it to North and West over next months. Even if not whole Singapore is available in 3D, I got personally interested to count floors, I used Google Street View where 3D map was not available, and by September 2018 I finished counting floors of 95% of HDB blocks, correcting all errors at blocks where I previously estimated height from shadow length.

Added since 2009, I renamed building descriptions over time and currently harmonized them for most common HDB blocks. In case of old SIT blocks with many distinctive models, building descriptions are a bit messy.

  • Individual unit floor plans: available for 80% of pre-BTO-era blocks (built up to 2004).
  • BTO launch brochures: available for BTO projects launched in 2010-2014.
  • BTO full brochures: available for BTO projects launched after 2012.
  • SERS full brochures: available for SERS replacement blocks announced after 2008.

Added in September 2017.

  • SERS prediciton by Teoalida: I personally indicated whenever blocks can get SERS or not, only (some of) pre-1980 blocks may be selected for redevelopment. There are 13 different pieces on text under SERS prediction.

Anything else to add? Your ideas are welcome!

HDB units database

Several people told me that require a database with 1 row for each unit instead of 1 row per building, for mailing. In theory I can create such database based on BTO brochures, but will take so much time and inability to do older blocks will results in an incomplete database that will hardly get sales to cover my effort.

In 2016 a property website wanted to hire me to expand their database, and sent me HDB units database.csv (111 units from block 24 Tanglin Halt Road – this sample CSV all what they sent me, I do not have other blocks, don’t ask).

Later other people told me that SingPost sell such unit numbers database for $10,000 and I assume that above property website has bought from SingPost. I do not know if $10,000 database include only HDB or also private housing, commercial and industrial units, etc. If anyone buy from SingPost, I appreciate if can share with me (I can pay a part of this price) so I can modify database to appear made by me and give it to other people needing the same (there may be legal issues).

That property website wanted my research service to add columns with number of bedrooms, bathrooms and floor area in sqm. While I can tell the flat type of any unit, by viewing HDB block in Google Streetview, I do not know position within block of each unit stack, would require going to block to block and see unit numbers map, overall the job would take a man’s life and is highly prone to mistakes and lack of accuracy, because:

In case of BTO blocks, while 4-room flat size is stated in brochure to be 90 sqm, there are stacks in which is 91-92 sqm. Same stack may have some floors with balconies (adding 2-3 sqm) and other floors not.

In case of old blocks some flat owners bought recess space while others not. Some <3-room flats have been adjoined.
