Hong Kong Housing Authority was formed in 1954, soon after a major file in Shek Kip Mei left 53000 people homeless on christmas day of 1953.
Shek Kip Mei Estate, the first public housing estate, was ready in 1954. The “flats” were just one room of 120 square feet, kitchen and bathrooms were communal, shared by all floor residents. Original plan was to allocate 24 square feet (2.2 square meters) per adult and half that for each child under 12. But due to the extreme shortage in available housing, a flat was shared by more than one family, 10-15 people per room were common in its first years, and during summer months, people were sleeping also on corridors.
Lower Ngau Tau Kok Estate, built in early 1960s, was in the first group of estates built with lifts. All blocks were 16-floor high, elevators were stopping at ground, 8th and 13th floors.
All were resettlement estates (temporary housing).
In 1961 the “low-cost housing” scheme was introduced through the construction of 62,380 flats in 18 public housing estates.
In 1963 the minimum area per person was increased to 35 sq ft (3.3 sq m).
In 1973 the government announced a ten-year plan for the public provision of housing, to provide everyone in Hong Kong with permanent, self-contained housing with a target of housing for 1.8 million people. Developing started for New Towns, away from urban area. The program was later extended to 15 years.
In 1978 the government launched Home Ownership Scheme, one year later introducing also Private Sector Participation Scheme, designed with private architects, which offers a bigger diversity in designs.
In 1998 the government launched Tenants Purchase Scheme, it was targeted to help increase ownership ratio to 70% by 2006 by selling rental flats to tenants.
Due to worsening economic situation, and complaints from private developers about bad effects of sales of public housing to their projects, construction of new HOS flats ended in 2003, also new launches of TPS were suspended.
Today the minimum area per person is 5.5 sq m (does anyone know since when?), aka all rental units which do not meet this minimum are subject to relocation elsewhere as soon as new rental flats are available.

Housing Authority – floor plans of main block types
Floor plans are in PDF format so you need to have Adobe Reader installed.
Point mouse on photos to see estate name!
Since late 2010, the Hong Kong Housing Authority website provides floor plans for most HOS and TPS estates, but requires a lot of searching through estates list to find floor plan of certain block type. So I decided to make here links to floor plans of most common block types. There is no way to find floor plans of PRH estates. In August 2012 a visitor told me that Housing Authority added floor plans for PRH standard blocks too here, no idea when they were added. The page of my website risk to become useless…
The block types refers more about apartments layout rather than block shape. For example, Concord blocks contains 47 sqm 3-room and 60 sqm 4-room, usually 8 apartments per floor in a + layout, but some blocks are shaped like Y and Z with 6 apartments per floor of same type, still being named Concord. Flat size specified is the Saleable area.

Hong Kong Housing Society was formed in 1948. The first rental estate, Sheung Li Uk, was built in 1952. Clague Garden Estate built in 1989 was the first Flat-For-Sale estate. Tivoli Garden built in 1995 was the first Sandwich Class Housing Scheme estate (public housing for middle-class priced like private housing).
No floor plan is published on their official website. Centadata contains floor plans of some of the ownership estates.
