Map of HDB blocks by year

Click block pins on map to view year built, number of floors, number of units, upgrading programmes, typical floor plans, chances to get SERS, etc. Use a computer (not phone) for best experience.

Open map on full screen.
There is also an alternate map: HDB blocks colored by floor height.

Cloud (699): Blocks under construction.

Forest (111): Blocks demolished or converted for other use than public housing after 2013.

I can guarantee 100% accuracy for block numbers, street addresses, unit numbers, lease years, number of units breakdown by flat type, etc.

I cannot guarantee accuracy for floor plans, they being added from my personal research, so I need your help, please report wrong floor plans!

Updated 6 September 2021: changed colors, added August BTO, manually added coordinates for about 300 demolished blocks, rest of demolished blocks to be added next days! If you don’t need them you can disable gray from legend. The map may change daily during September 2021 because I am updating it with more floor plans and optimize block model naming.

Please contribute if you have more info about demolished blocks (number of units, flat types, etc).

How to use map and search search blocks

The box in lower-right corner of map can be used to search Google Maps addresses. To search in HDB Database (data added by me) you need to click 3 dots menu > Search (phone users) or map search icon (computer users). Don’t confuse map search icon with website search box (top green bar).

ZeeMaps have a BUG on maps with more than 7500 pins, the pins get smaller and appear under Google Maps labels thus harder to click. I reported the bug and until they fix it, you can avoid the bug: in “search the map” go in Colors tab and disable a color that isn’t used then click search, all HDB blocks will be shown with big circle markers easier to click.

Or you can filter further:

Show only blocks from certain town / neighborhood: choose City > contains > type for example Telok Blangah.

Find a block by number or street name: choose Name > contains > type a block number > map will show all blocks with that number > zoom to desired town. Don’t write both block number and street name unless you know the format I named blocks.

Show only blocks containing certain flat type: choose Number of units > contains > type “3-room”, “executive”, etc.

Show only blocks containing premium apartments: choose Block model > contains > type “premium”.

Filter blocks that underwent certain upgrades: choose Upgrading programmes > contains > type HIP (or other upgrading programme).

Filter blocks taller than # floors: choose Total floors > Greater than > type a number.

For SERS hunters: only (some of) brown and red blocks (pre-1980) may be selected for redevelopment, do not waste time clicking other colors. There are only 13 different pieces on text under SERS prediction. See also list of potential SERS sites.

Map of HDB blocks


The map is powered by HDB Blocks Database, an Excel file that I spent about 500 hours compiling data manually since 2009. Excel table is available for paid download for professional use.

I made the interactive map 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 criteria. If anyone thinks that is better to use different colors that indicate block types and construction years, please tell.

At 2018 update I quickly added 70 floor plans with dimensions, that does apply for 93% of 1960-1991 blocks and 54% of 1991-2005 blocks. Since 1990s HDB started building many distinctive layouts thus it require more effort for me to link correct floor plans to correct blocks (I have over 1000 floor plans in my computer), so I left them for a later time when I will be LESS BUSY.

After launch of BTO system in 2001, all blocks completed after 2005 are designed uniquely, meaning that a floor plan for a BTO won’t match any other BTO, it is too difficult to find floor plans for EVERY unit in EVERY BTO, so I did not bothered adding individual unit floor plans with dimensions, instead I linked BTO brochures showing floor plans for whole block, without dimensions.
