An interactive map “Made by Teoalida” with HDB blocks colored by year built, as alternative to official HDB Map Services. Blocks can recolored by number of floors.

HDB DatabaseClick colored markers on map (one block at time) to view year built, number of floors, number of units, upgrading programmes, typical floor plans, chances to get SERS, etc.

Interactive map created in 2017. In 2018 I added floor plans from most popular old blocks. As September 2021 map contains floor plans for 96% of 1960-1991 blocks and 62% of 1991-2005 blocks.

In the past a floor plan was aplicable for hundreds blocks, adding floor plans for 2005-present blocks is an on-going tedious job, because all BTO blocks (launched since 2001) plus some 1990s blocks are unique designed, meaning that a floor plan from a BTO is not aplicable for any other BTO, in theory I need to find over 100 floor plans for each year of BTO launches. I am searching on google images each block number, few times per year, hoping that someone posted a flat for sale including floor plan. Please contribute with missing floor plans and report wrong ones!

How to search / filter blocks on map

Click magnify button in top-left (next to Map / Satellite) and use GO TO box to navigate to a specific location, town, block number, street name or postal code.

Use filter boxes to show only blocks containing specific info:

  • Project name: type “BTO 2020” or “SERS 2003” to see projects sold via specific scheme in a specific year, or type a BTO name to see only it.
  • Completion year: type a number to see blocks completed in specific year, typing 20 show all blocks completer after 2000.
  • Block era: type completed, demolished, under construction, typing 19 show blocks built from 1930s to 2005, or 20 show blocks built after 1997.
  • Highest floor: type a number to see blocks with a specific number of floors.
  • Number of units: type 1-room, 2-room, 3-room, 4-room, 5-room, executive, studio, etc, to see blocks having a particular flat type.
  • Unit number: type stack number, example: 345, not #12-345 to see in which block that unit is located (available for recent blocks, most blocks built before 2005 don’t have unit numbers in database).
  • Possible floor plans: copy-paste URL of a floor plan to see in which blocks can be found, or “to be added” to see blocks without floor plans (you can contribute by sending me floor plans).

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

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

I made myself this list in 2011 after seeing a list of “HDB flat types & models” that was wrong and incomplete, original author is unknown but it was copied by many blogs. In 2025 I recreated list in table format, © Teoalida for publication on www.housingmap.sg, do not copy it without my approval!

Flat type abbreviation: STD = Standard, I = Improved, NG = New Generation, S = Simplified, A = Model A. Some people wrongly abbreviate Standard as S instead of STD. Flat types are no longer used in sales brochures since 1998, but are still displayed in the Resale flat prices.

Flat type naming represent approximate size in sqm and number of rooms, NOT the floor plan layout. Do not associate sample layouts with flat types, other different layouts do exists with same flat type naming.

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.
Since late 1990s block types are no longer used officially. HDB blocks are now a mixture between point and 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.

Beware of HDB naming system!

HDB flat types (4-Room, 5-Room, etc) does NOT indicate actual number of rooms, it define 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.

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: renovated flats with installed doors, tiles, wall paint, kitchen cabinets.
Standard contract: flats with raw concrete waiting for your renovation, doors optional.

Premium flats were introduced in mid-1990s all over towns, beside renovated flats, they also feature better outdoor landscape, and in some cases, basement carpark. Most premium flats have full-height windows, but this is not a rule. Since late 2000s only good locations (near MRT or near waterfront) feature premium flats. In 2014 only 1 of the 32 BTO launched was premium (in january). Since May 2015 BTO, brochures no longer indicate if flats are standard or premium. Does anyone know if HDB is still building premium flats?

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 news reports showed residents upset about quality especially in later DBSS projects.

Latest BTO projects

Build-To-Order was introduced in April 2001, currently BTO sale launches are in February, June, October in which you have a week to apply for a BTO flat.

BTO locations (towns) are announced 4 months in advance on homes.hdb.gov.sg. Once they are launched, you can see BTO name, 3D render, number of flats, prices and floor plans, buut only for a week during application period, then HDB delete them, and 1-2 months later they publish PDF brochure, supposedly for invited applicants only, but anyone can get brochure by guessing URL.

    1. First time you contacted me on 23 July, you said “i’m searching for a 60 unit apartment building” and I assumed that you came at me for architectural design services, but you never told me project location.

      Now you keep posting comments talking about patents and inventions. I am totally confused what do you need from me? How I can help you?

  3. Really impressed to come across this interactive HDB map while researching on resale flat to buy. This Teoalida is a real geek who is passionate and serious about housing. He replies queries promptly (in person), much better than those chat services in banks!

  4. Hi! I’m LunarTesting23, a lift enthusiast. Based on my observations when I went to Balam Road one day, I saw that the lifts got replaced into newer ones. Could this mean that the Balam Road HDBs may not fall under SERS for some time?

  5. Blocks 45, 48 & 49 Stirling Road are were the first few blocks of flats completed in October 1960, just months after the Housing and Development Board (HDB) was formed in February 1960.

Additionaly, this website capture more on the case https://www.daffodilsw.com/ai-development-services/ checkout now.

  7. I think you made a few mistakes:
    • EastWave @ Canberra is standard not premium.
    • Waterway Terraces II and Coral Spring (in Sengkang) are premium flats.

  8. HDB price trends are shaped by a range of factors, including economic conditions, government policies, and market demand. The Housing and Development Board (HDB) has played a crucial role in maintaining housing affordability and stability over the years.

  10. The effort put into collecting floor plans and categorizing blocks by era, design, and completion year is impressive. I can see how challenging it must be to find unique floor plans for newer BTO blocks. Keep up the great work, Teoalida! This map is a fantastic tool for analysis and exploration.

  11. I really appreciate the effort put into collecting floor plans and maintaining such comprehensive data over the years. It’s amazing how much information is available, from building eras to specific upgrading programs.

  12. Teoalida’s HDB map provides a level of detail and customization that’s sorely missing elsewhere. The ability to see year built and floor count at a glance, plus delve into specific unit details, makes property research so much easier.

  13. Thanks for this Singapore housing guide! The tip about landscape mode for the large table on phones is super practical. I found it very insightful how BTO locations are announced ahead, but exact prices and floor plans only on launch day. Great read!
