In 2018 I added floor plans from most popular old blocks. By 2021 96% of 1960-1991 blocks and 62% of 1991-2005 blocks had at least 1 floor plan.\nIn the past a floor plan was applicable for hundreds blocks, adding floor plans for 2005-present blocks is an\non-going tedious job\n, because all BTO blocks (launched since 2001) plus some 1990s blocks are unique designed, meaning that a floor plan from a BTO is not applicable 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.\nPlease contribute with missing floor plans and report wrong ones!\nLatest BTO projects\nBuild-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.\nBTO locations (towns) are announced 4 months in advance on\nhomes.hdb.gov.sg\n. Once they are launched, you can see BTO name, 3D render, number of flats, prices and floor plans, but 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\nguessing URL\n.\nFor complete list of (older) BTO projects, see\nwww.housingmap.sg\/bto\nTown name\nBTO name\n . . . .\n . . . .\n . . . .\nUnits\nLaunch date\nEstimated\ncompletion\ndate (\nnote\n)\nType\nBrochure\n(\nnote\n)\nSembawang\nSembawang Voyage\n1173\n04 Feb 2026\n2Q 2030\nstandard\nbrochure\nSembawang\nSembawang Deck\n777\n04 Feb 2026\n3Q 2029\nstandard\nbrochure\nTampines\nTampines Bliss\n284\n04 Feb 2026\n3Q 2028\nstandard\nbrochure\nTampines\nTampines Nova\n255\n04 Feb 2026\n2Q 2029\nPlus\nbrochure\nToa Payoh\nKim Keat Crest\n1151\n04 Feb 2026\n4Q 2029\nPlus\nbrochure\nBukit Merah\nRedhill Peaks\n1052\n04 Feb 2026\n2Q 2031\nPRIME\nbrochure\nBukit Merah\nBerlayar Residences\n880\n15 Oct 2025\n56 months\nPRIME\nbrochure\nBishan\nBishan Terraces\n538\n15 Oct 2025\n47 months\nPRIME\nbrochure\nYishun\nChencharu Grove\n826\n15 Oct 2025\n31 months\nstandard\nbrochure\nSengkang\nFernvale Plains\n1037\n15 Oct 2025\n32 months\nstandard\nbrochure\nToa Payoh\nMount Pleasant Crest\n1348\n15 Oct 2025\n59 months\nPRIME\nbrochure\nAng Mo Kio\nOak Ville @ AMK\n1425\n15 Oct 2025\n49 months\nPlus\nbrochure\nBedok\nPing Yi Court\n862\n15 Oct 2025\n33 months\nstandard\nbrochure\nBukit Merah\nRedhill Peaks\n1021\n15 Oct 2025\n53 months\nPRIME\nbrochure\nJurong East\nTeban Heights\n638\n15 Oct 2025\n48 months\nstandard\nbrochure\nYishun\nYishun Glade\n569\n15 Oct 2025\n31 months\nstandard\nbrochure\nBukit Merah\nAlexandra Peaks\n498\n23 Jul 2025\n56 months\nPRIME\nbrochure\nBukit Merah\nAlexandra Vista\n609\n23 Jul 2025\n47 months\nPRIME\nbrochure\nBukit Panjang\nBangkit Breeze\n643\n23 Jul 2025\n35 months\nstandard\nbrochure\nClementi\nClementi Emerald\n753\n23 Jul 2025\n34 months\nPRIME\nbrochure\nSembawang\nSembawang Beacon\n775\n23 Jul 2025\n36 months\nstandard\nbrochure\nTampines\nSimei Symphony\n380\n23 Jul 2025\n42 months\nstandard\nbrochure\nToa Payoh\nToa Payoh Ascent\n741\n23 Jul 2025\n41 months\nPRIME\nbrochure\nWoodlands\nWoodlands North Grove\n1148\n23 Jul 2025\n55 months\nstandard\nbrochure\nYishun\nChencharu Green\n683\n10 Feb 2025\n47\/48 months\nstandard\nbrochure\nYishun\nChencharu Vines\n848\n10 Feb 2025\n37 months\nstandard\nbrochure\nQueenstown\nStirling Horizon\n1126\n10 Feb 2025\n38 months\nplus\nbrochure\nKallang\/Whampoa\nTanjong Rhu Parc Front\n812\n10 Feb 2025\n55 months\nPRIME\nbrochure\nWoodlands\nWoodlands North Verge\n1563\n10 Feb 2025\n48 months\nstandard\nbrochure\nHDB key statistics\nI took data from Key Statistics section of HDB Annual Reports since 1990 to present into an \nExcel file\n and generated the below charts.

Flat types are no longer used in sales brochures since 1998, but are still displayed in the Resale flat prices.\nFlat type naming represent approximate size in sqm and number of rooms, NOT the floor plan layout.

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.\nBeware of HDB naming system!\nHDB 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 (\nexample\n), while some 5-Room Improved from same period had only 3 (but big) bedrooms and a living room (\nexample\n).\nBefore 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.\nFrom 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.\nAfter 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.\nMy opinion:\n 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.\nFrequently asked questions\nWhat is the difference between Studio and 2-Room\nFloor plan is similar, BUT…\nStudio 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.\n2-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.\nStudio 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.\nWhat is the difference between 4-Room and 5-Room\nThe 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!\nWhat is the difference between Standard and Premium HDB flats\nPremium contract: renovated flats with installed doors, tiles, wall paint, kitchen cabinets.\nStandard contract: flats with raw concrete waiting for your renovation, doors optional.\nPremium 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?\nWhat is the difference between BTO and DBSS flats\nBTO are sold by HDB at subsidized prices while DBSS are sold by profit-hungry private developers at super fucking crazy outrageous high prices.\nBeside 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.\nDBSS flats are supposedly higher quality than BTO premium flats, but news reports showed residents upset about quality especially in later DBSS projects.\nbuy HDB loan, season parking, rental","attrs_markdown":"[Skip to content](https:\/\/www.housingmap.sg\/#content)\n\n[Housing Map .sg](https:\/\/www.housingmap.sg\/)\n\n- [HDB map by year](https:\/\/www.housingmap.sg\/)\n- [HDB map by height](https:\/\/www.housingmap.sg\/hdb-map-height\/)\n- [HDB history & floor plans](https:\/\/www.housingmap.sg\/tag\/history\/)\n  -

In 2018 I added floor plans from most popular old blocks. By 2021 96% of 1960-1991 blocks and 62% of 1991-2005 blocks had at least 1 floor plan.\n\nIn the past a floor plan was applicable 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 applicable 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\\!**\n\n## Latest BTO projects\nBuild-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.\n\nBTO locations (towns) are announced 4 months in advance on [homes.hdb.gov.sg](https:\/\/homes.hdb.gov.sg\/home\/landing). Once they are launched, you can see BTO name, 3D render, number of flats, prices and floor plans, but 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](https:\/\/www.housingmap.sg\/bto\/#brochures)**.**\n\nFor complete list of (older) BTO projects, see

present into an **[Excel file](https:\/\/www.teoalida.com\/database\/HDB-Key-Statistics-by-Teoalida.xlsx)** and generated the below charts. Use keys ↑↓ to navigate through years and see town evolution.\n\nRead more: <https:\/\/www.housingmap.sg\/hdb-statistics\/>\n\nValues\n\nPercentage\n\n## HDB price trends\nHDB Resale Price Index DOUBLED from 2007 to 2013 due to low construction, dropped 10% to 2015 then stabilized until 2020 when COVID-19 pandemic triggered another bubble. The growth slowed down as 2025 but the future remains uncertain as Singapore economy is influenced by external factors (Ukraine war, US-China trade war, etc).\n\nHowever the price trends were NOT similar across towns and block age.\n\nRead more <https:\/\/www.housingmap.sg\/hdb-prices\/>\n\n## Need bulk data for analysis?\nBeside this, I made very detailed **[HDB Blocks Database](https:\/\/www.housingmap.sg\/hdb-database\/)** 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.\n\n[![HDB Database](https:\/\/www.housingmap.sg\/data\/HDB-Database.png)](https:\/\/www.housingmap.sg\/hdb-database\/)\n\n## Flat types (most popular floor plans)\nI 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\\!**\n\nFlat 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.\n\nFlat 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.\n\n| Most popular floor plans | Flat type | Year built | Notes |\n|---|---|---|---|\n|   | **1960s-1970s flat types (refuse chute in kitchen)** |   |   |\n|   | 1-Room Emergency | 1960-? | all demolished |\n|   | 2-Room Emergency | 1960-? | demolished except 5 blocks |\n|   | 1-Room

– long narrow corridor-style block with 4 to 40+ units per floor.  \n**Point block** – 4 apartments per floor, no corridors, being placed at distance from other blocks.  \n**Atrium block** – a term introduced in 1990s denoting blocks with more than 4 units per floor but without long corridors.  \nSince 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.\n\n### See more floor plans & history by decade\n[![Singapore Improvement Trust](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Singapore-Improvement-Trust-1953.jpg)](https:\/\/www.housingmap.sg\/sit\/)\n\n###### [SIT history: 1930s to 1950s](https:\/\/www.housingmap.sg\/sit\/)\n\n[![Redhill](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Redhill.jpg)](https:\/\/www.housingmap.sg\/hdb-1960\/)\n\n###### [HDB history and floor plans 1960s](https:\/\/www.housingmap.sg\/hdb-1960\/)\n\n[![Ang Mo Kio](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Ang-Mo-Kio-scaled.jpg)](https:\/\/www.housingmap.sg\/hdb-1970\/)\n\n###### [HDB history and floor plans 1970s](https:\/\/www.housingmap.sg\/hdb-1970\/)\n\n[![Bukit Batok](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Bukit-Batok-scaled.jpg)](https:\/\/www.housingmap.sg\/hdb-1980\/)\n\n###### [HDB history and floor plans 1980s](https:\/\/www.housingmap.sg\/hdb-1980\/)\n\n[![Bishan](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Bishan.jpg)](https:\/\/www.housingmap.sg\/hdb-1990\/)\n\n###### [HDB history and floor plans 1990s](https:\/\/www.housingmap.sg\/hdb-1990\/)\n\n[![Punggol](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Punggol.jpg)](https:\/\/www.housingmap.sg\/hdb-2000\/)\n\n###### [HDB history and floor plans 2000s](https:\/\/www.housingmap.sg\/hdb-2000\/)\n\n[![Punggol Waterway](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Punggol-Waterway.webp)](https:\/\/www.housingmap.sg\/hdb-2010\/)\n\n###### [HDB history and floor plans 2010s](https:\/\/www.housingmap.sg\/hdb-2010\/)\n\n[![Sky Residence @ Dawson](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Sky-Residence-Dawson.jpg)](https:\/\/www.housingmap.sg\/hdb-2020\/)\n\n###### [HDB history 2020s](https:\/\/www.housingmap.sg\/hdb-2020\/)\n\n[![Boon Lay](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Boon-Lay-scaled.jpg)](https:\/\/www.housingmap.sg\/jtc\/)\n\n###### [JTC history and floor plans](https:\/\/www.housingmap.sg\/jtc\/)\n### Beware of HDB naming system\\!\nHDB 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](https:\/\/www.housingmap.sg\/hdb-floor-plans\/HDB-1989-1991-4A-corridor.png)), while some 5-Room Improved from same period had only 3 (but big) bedrooms and a living room ([example](https:\/\/www.housingmap.sg\/hdb-floor-plans\/HDB-1984-1988-5I-corridor-end-120sqm.png)).\n\nBefore 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.\n\nFrom 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.\n\nAfter 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.\n\n**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.\n\n## Lists and databases\n[![HDB Database](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Singapore-HDB.webp)](https:\/\/www.housingmap.sg\/hdb-database\/)\n\n###### [HDB blocks database](https:\/\/www.housingmap.sg\/hdb-database\/)\n\n[![HDB Resale Flat Prices Database](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/HDB-Resale-Flat-Prices-Database.png)](https:\/\/www.housingmap.sg\/hdb-resale-flat-prices\/)\n\n###### [HDB resale flat prices database](https:\/\/www.housingmap.sg\/hdb-resale-flat-prices\/)\n\n[![Condo Database](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Singapore-Condo.jpg)](https:\/\/www.housingmap.sg\/condo-database\/)\n\n###### [Condo database](https:\/\/www.housingmap.sg\/condo-database\/)\n\n[![Condo Database Management Corporations](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Condo-Database-Management-Corporations.png)](https:\/\/www.housingmap.sg\/mcst\/)\n\n###### [MCST database](https:\/\/www.housingmap.sg\/mcst\/)\n\n[![Postal codes](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/postal-codes-in-singapore.jpg)](https:\/\/www.housingmap.sg\/buildings-database\/)\n\n###### [Database of all buildings in Singapore with postal codes](https:\/\/www.housingmap.sg\/buildings-database\/)\n\n[![BTO brochures](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/BTO-brochures.png)](https:\/\/www.housingmap.sg\/bto\/)\n\n###### [List of BTO projects, brochures and flat prices](https:\/\/www.housingmap.sg\/bto\/)\n\n[![City View @ Boon Keng](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/City-View-Boon-Keng.jpg)](https:\/\/www.housingmap.sg\/dbss\/)\n\n###### [List of DBSS projects](https:\/\/www.housingmap.sg\/dbss\/)\n###### [List of SBF launches](https:\/\/www.housingmap.sg\/sbf\/)\n[![Kim Keat Avenue](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Kim-Keat-Avenue-demolition.jpg)](https:\/\/www.housingmap.sg\/sers\/)\n\n###### [List of SERS sites](https:\/\/www.housingmap.sg\/sers\/)\n\n[![Braddell View](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Braddell-View.jpg)](https:\/\/www.housingmap.sg\/hudc\/)\n\n###### [List of HUDC estates](https:\/\/www.housingmap.sg\/hudc\/)\n\n[![executive condominium](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/condominium.jpg)](https:\/\/www.housingmap.sg\/ec\/)\n\n###### [List of Executive Condos](https:\/\/www.housingmap.sg\/ec\/)\n\n[![Singapore MRT and LRT map](https:\/\/www.housingmap.sg\/wordpress\/wp-content\/uploads\/Singapore_MRT_and_LRT_System_Map-da8abf.svg)](https:\/\/www.housingmap.sg\/mrt\/)\n\n###### [List of MRT and LRT stations](https:\/\/www.housingmap.sg\/mrt\/)\n### Frequently asked questions\n###### What is the difference between Studio and 2-Room\nFloor plan is similar, BUT…  \nStudio 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.  \n2-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.\n\nStudio 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.\n\n###### What is the difference between 4-Room and 5-Room\nThe 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\\!\n\n###### What is the difference between Standard and Premium HDB flats\nPremium contract: renovated flats with installed doors, tiles, wall paint, kitchen cabinets.  \nStandard contract: flats with raw concrete waiting for your renovation, doors optional.\n\nPremium 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?\n\n###### What is the difference between BTO and DBSS flats\nBTO are sold by HDB at subsidized prices while DBSS are sold by profit-hungry private developers at super fucking crazy outrageous high prices.  \nBeside 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.  \nDBSS flats are supposedly higher quality than BTO premium flats, but news reports showed residents upset about quality especially in later DBSS projects.\n\nbuy HDB loan, season parking, rental\n\n## 1 comments about Home Page\n1. ![](https:\/\/secure.gravatar.com\/avatar\/7b024467d41591ddfbb28ed00fd8140060ac79ab6d13e9fc3705436cb0a1bdea?s=50&d=mm&r=g)\n   \n   [happy horse ai](https:\/\/happyhorse-ai.co\/)\n   \n   [April 10, 2026 at 8:17 am](https:\/\/www.housingmap.sg\/#comment-22420)\n   \n   [Reply](https:\/\/www.housingmap.sg\/#comment-22420)\n   \n   thanks share\n## Leave a comment [Cancel reply](https:\/\/www.housingmap.sg\/#respond)\n\n### FAQ\n##### Can you provide additional info?\nAsking me for floor plans is usually pointless because all floor plans I have can be accessed by clicking each HDB block on the map on homepage [www.housingmap.sg](https:\/\/www.housingmap.sg\/) (90% blocks have at least 1 floor plan or brochure attached).\n\nIf you require other additional info than floor plans that is not already on website, you can ask.\n\n##### Can I help you?\nYou can contribute by sending floor plans that I don't have, missing information about demolished blocks or Singapore heritage, or any other ideas to make website better.\n\n##### What other services do you offer?\nI am author of over 100 [databases](https:\/\/www.teoalida.com\/database\/index\/) and over 100 [arhitectural designs](https:\/\/www.teoalida.com\/design\/) and make a living from selling them, so I no longer need to make new projects on request basis.

In 2018 I added floor plans from most popular old blocks. By 2021 96% of 1960-1991 blocks and 62% of 1991-2005 blocks had at least 1 floor plan.\n\nIn the past a floor plan was applicable 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 applicable 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\\!**\n\n## Latest BTO projects\nBuild-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.\n\nBTO locations (towns) are announced 4 months in advance on [homes.hdb.gov.sg](https:\/\/homes.hdb.gov.sg\/home\/landing). Once they are launched, you can see BTO name, 3D render, number of flats, prices and floor plans, but 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](https:\/\/www.housingmap.sg\/bto\/#brochures)**.**\n\nFor complete list of (older) BTO projects, see

The growth slowed down as 2025 but the future remains uncertain as Singapore economy is influenced by external factors (Ukraine war, US-China trade war, etc).\n\nHowever the price trends were NOT similar across towns and block age.\n\nRead more <https:\/\/www.housingmap.sg\/hdb-prices\/>\n\n## Need bulk data for analysis?\nBeside this, I made very detailed **[HDB Blocks Database](https:\/\/www.housingmap.sg\/hdb-database\/)** 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.\n\n[![HDB Database](https:\/\/www.housingmap.sg\/data\/HDB-Database.png)](https:\/\/www.housingmap.sg\/hdb-database\/)\n\n## Flat types (most popular floor plans)\nI 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\\!**\n\nFlat 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.\n\nFlat 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.\n\n| Most popular floor plans | Flat type | Year built | Notes |\n|---|---|---|---|\n|

| 3gen flat | 115 sqm (introduced in 2013 BTO, completed 2017-present) | 4 bedrooms, 3 toilets, home ownership restricted for couples + 1 additional family relative |\n### Block types\n**Slab block** – long narrow corridor-style block with 4 to 40+ units per floor.  \n**Point block** – 4 apartments per floor, no corridors, being placed at distance from other blocks.  \n**Atrium block** – a term introduced in 1990s denoting blocks with more than 4 units per floor but without long corridors.  \nSince 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.\n### Beware of HDB naming system\\!\nHDB 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](https:\/\/www.housingmap.sg\/hdb-floor-plans\/HDB-1989-1991-4A-corridor.png)), while some 5-Room Improved from same period had only 3 (but big) bedrooms and a living room ([example](https:\/\/www.housingmap.sg\/hdb-floor-plans\/HDB-1984-1988-5I-corridor-end-120sqm.png)).\n\nBefore 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.\n\nFrom 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.\n\nAfter 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.\n\n**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.\n\n### Frequently asked questions\n###### What is the difference between Studio and 2-Room\nFloor plan is similar, BUT…  \nStudio 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.  \n2-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.\n\nStudio 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.\n\n###### What is the difference between 4-Room and 5-Room\nThe 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\\!\n\n###### What is the difference between Standard and Premium HDB flats\nPremium contract: renovated flats with installed doors, tiles, wall paint, kitchen cabinets.  \nStandard contract: flats with raw concrete waiting for your renovation, doors optional.\n\nPremium 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?\n\n###### What is the difference between BTO and DBSS flats\nBTO are sold by HDB at subsidized prices while DBSS are sold by profit-hungry private developers at super fucking crazy outrageous high prices.  \nBeside 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.  \nDBSS flats are supposedly higher quality than BTO premium flats, but news reports showed residents upset about quality especially in later DBSS projects.\n\nbuy HDB loan, season parking, rental","meta_canonical":null}

Click colored markers to view year built, number of floors, number of units, upgrading programmes, typical floor plans, chances to get SERS, etc. Use filters to show blocks by specific criteria: filter examples . Interactive map created in 2017. In 2018 I added floor plans from most popular old blocks. By 2021 96% of 1960-1991 blocks and 62% of 1991-2005 blocks had at least 1 floor plan. In the past a floor plan was applicable 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 applicable 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! 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, but 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 .

The growth slowed down as 2025 but the future remains uncertain as Singapore economy is influenced by external factors (Ukraine war, US-China trade war, etc). However the price trends were NOT similar across towns and block age. Read more https://www.housingmap.sg/hdb-prices/ Need bulk data for analysis? Beside this, I made very detailed HDB Blocks Database 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. Flat types (most popular 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. Most popular floor plans Flat type Year built Notes 1960s-1970s flat types (refuse chute in kitchen) 1-Room Emergency 1960-? all demolished 2-Room Emergency 1960-? demolished except 5 blocks 1-Room Standard 1960-? no evidence if it existed, in my opinion should exists 2-Room Standard 1960-1970 around 41 sqm one WC/shower 3-Room Standard 1960-1970 around 50-55 sqm one WC/shower 4-Room Standard 1960-1970 around 70-75 sqm one WC/shower 1-Room Improved 1966-1980 supposedly 33 sqm but multiple layouts exists 2-Room Improved 1966-1980 usually 44 sqm separate WC and shower 3-Room Improved 1966-1980 usually 60 sqm 3½-Room I Modified 69 sqm separate WC and shower 4-Room Improved 1966-1980 usually 82-84 sqm separate WC and shower 5-Room Standard 1974-1980 usually 117-123 sqm two small toilets 5-Room Improved 1976-1985 usually 117-123 sqm two small toilets 1970s-1980s flat types (refuse chute in kitchen) 3-Room New Generation 1975-1986 usually 67 sqm 3½-Room NG Modified 82 sqm two small toilets 4-Room New Generation 1975-1986 usually 92 sqm two small toilets 5-Room Improved 1978-1990s usually 121-123 sqm two small toilets 3-Room Simplified 1984-1988 usually 64 sqm two full-size toilets 4-Room Simplified 1984-1988 usually 84 sqm two full-size toilets 3-Room Model A 1982-1989 usually 73-75 sqm 3½-Room A Modified 88-90 sqm two full-size toilets 4-Room Model A 1982-1990s usually 105-108 sqm two full-size toilets 5-Room Model A 1981-1985 usually 133-135 sqm two full-size toilets 5-Room Model A Maisonette 1982-1984 most 140 sqm some up to 155 sqm two full-size toilets Executive Apartment 1983-1990s usually 142-146 sqm ONE floor Executive Maisonette 1983-1990s most 147 sqm some up to 160 sqm TWO floors Multi-Generation 1987 132 sqm / 151-171 sqm most 166 sqm ONE floor, 2 entrances 4-Room / 5-Room / Executive “Jumbo” 1992-1996 around 90-192 sqm adjoined by HDB, fresh leases, 1 entrance, 2 or 3 full-size toilets. 4-Room / 5-Room / Executive Adjoined Flat any year around 90-175 sqm adjoined by owners, original leases, 2 entrances unless owner walled one, 2 kitchens unless owner converted one into something else, up to 4 toilets.

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. buy HDB loan, season parking, rental

Click colored markers to view year built, number of floors, number of units, upgrading programmes, typical floor plans, chances to get SERS, etc. Use filters to show blocks by specific criteria: [filter examples](https://www.housingmap.sg/filters/). Interactive map created in 2017. In 2018 I added floor plans from most popular old blocks. By 2021 96% of 1960-1991 blocks and 62% of 1991-2005 blocks had at least 1 floor plan. In the past a floor plan was applicable 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 applicable 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\! ## 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](https://homes.hdb.gov.sg/home/landing). Once they are launched, you can see BTO name, 3D render, number of flats, prices and floor plans, but 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](https://www.housingmap.sg/bto/#brochures).

into an [Excel file](https://www.teoalida.com/database/HDB-Key-Statistics-by-Teoalida.xlsx) and generated the below charts. Use keys ↑↓ to navigate through years and see town evolution. Read more: <https://www.housingmap.sg/hdb-statistics/> Values Percentage ## HDB price trends HDB Resale Price Index DOUBLED from 2007 to 2013 due to low construction, dropped 10% to 2015 then stabilized until 2020 when COVID-19 pandemic triggered another bubble. The growth slowed down as 2025 but the future remains uncertain as Singapore economy is influenced by external factors (Ukraine war, US-China trade war, etc). However the price trends were NOT similar across towns and block age. Read more <https://www.housingmap.sg/hdb-prices/> ## Need bulk data for analysis? Beside this, I made very detailed [HDB Blocks Database](https://www.housingmap.sg/hdb-database/) 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. [![HDB Database](https://www.housingmap.sg/data/HDB-Database.png)](https://www.housingmap.sg/hdb-database/) ## Flat types (most popular 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. \| Most popular floor plans \| Flat type \| Year built \| Notes \| \|---\|---\|---\|---\|

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. ### See more floor plans & history by decade [![Singapore Improvement Trust](https://www.housingmap.sg/wordpress/wp-content/uploads/Singapore-Improvement-Trust-1953.jpg)](https://www.housingmap.sg/sit/) ###### [SIT history: 1930s to 1950s](https://www.housingmap.sg/sit/) [![Redhill](https://www.housingmap.sg/wordpress/wp-content/uploads/Redhill.jpg)](https://www.housingmap.sg/hdb-1960/) ###### [HDB history and floor plans 1960s](https://www.housingmap.sg/hdb-1960/) [![Ang Mo Kio](https://www.housingmap.sg/wordpress/wp-content/uploads/Ang-Mo-Kio-scaled.jpg)](https://www.housingmap.sg/hdb-1970/) ###### [HDB history and floor plans 1970s](https://www.housingmap.sg/hdb-1970/) [![Bukit Batok](https://www.housingmap.sg/wordpress/wp-content/uploads/Bukit-Batok-scaled.jpg)](https://www.housingmap.sg/hdb-1980/) ###### [HDB history and floor plans 1980s](https://www.housingmap.sg/hdb-1980/) [![Bishan](https://www.housingmap.sg/wordpress/wp-content/uploads/Bishan.jpg)](https://www.housingmap.sg/hdb-1990/) ###### [HDB history and floor plans 1990s](https://www.housingmap.sg/hdb-1990/) [![Punggol](https://www.housingmap.sg/wordpress/wp-content/uploads/Punggol.jpg)](https://www.housingmap.sg/hdb-2000/) ###### [HDB history and floor plans 2000s](https://www.housingmap.sg/hdb-2000/) [![Punggol Waterway](https://www.housingmap.sg/wordpress/wp-content/uploads/Punggol-Waterway.webp)](https://www.housingmap.sg/hdb-2010/) ###### [HDB history and floor plans 2010s](https://www.housingmap.sg/hdb-2010/) [![Sky Residence @ Dawson](https://www.housingmap.sg/wordpress/wp-content/uploads/Sky-Residence-Dawson.jpg)](https://www.housingmap.sg/hdb-2020/) ###### [HDB history 2020s](https://www.housingmap.sg/hdb-2020/) [![Boon Lay](https://www.housingmap.sg/wordpress/wp-content/uploads/Boon-Lay-scaled.jpg)](https://www.housingmap.sg/jtc/) ###### [JTC history and floor plans](https://www.housingmap.sg/jtc/) ### 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](https://www.housingmap.sg/hdb-floor-plans/HDB-1989-1991-4A-corridor.png)), while some 5-Room Improved from same period had only 3 (but big) bedrooms and a living room ([example](https://www.housingmap.sg/hdb-floor-plans/HDB-1984-1988-5I-corridor-end-120sqm.png)). 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. ## Lists and databases [![HDB Database](https://www.housingmap.sg/wordpress/wp-content/uploads/Singapore-HDB.webp)](https://www.housingmap.sg/hdb-database/) ###### [HDB blocks database](https://www.housingmap.sg/hdb-database/) [![HDB Resale Flat Prices Database](https://www.housingmap.sg/wordpress/wp-content/uploads/HDB-Resale-Flat-Prices-Database.png)](https://www.housingmap.sg/hdb-resale-flat-prices/) ###### [HDB resale flat prices database](https://www.housingmap.sg/hdb-resale-flat-prices/) [![Condo Database](https://www.housingmap.sg/wordpress/wp-content/uploads/Singapore-Condo.jpg)](https://www.housingmap.sg/condo-database/) ###### [Condo database](https://www.housingmap.sg/condo-database/) [![Condo Database Management Corporations](https://www.housingmap.sg/wordpress/wp-content/uploads/Condo-Database-Management-Corporations.png)](https://www.housingmap.sg/mcst/) ###### [MCST database](https://www.housingmap.sg/mcst/) [![Postal codes](https://www.housingmap.sg/wordpress/wp-content/uploads/postal-codes-in-singapore.jpg)](https://www.housingmap.sg/buildings-database/) ###### [Database of all buildings in Singapore with postal codes](https://www.housingmap.sg/buildings-database/) [![BTO brochures](https://www.housingmap.sg/wordpress/wp-content/uploads/BTO-brochures.png)](https://www.housingmap.sg/bto/) ###### [List of BTO projects, brochures and flat prices](https://www.housingmap.sg/bto/) [![City View @ Boon Keng](https://www.housingmap.sg/wordpress/wp-content/uploads/City-View-Boon-Keng.jpg)](https://www.housingmap.sg/dbss/) ###### [List of DBSS projects](https://www.housingmap.sg/dbss/) ###### [List of SBF launches](https://www.housingmap.sg/sbf/) [![Kim Keat Avenue](https://www.housingmap.sg/wordpress/wp-content/uploads/Kim-Keat-Avenue-demolition.jpg)](https://www.housingmap.sg/sers/) ###### [List of SERS sites](https://www.housingmap.sg/sers/) [![Braddell View](https://www.housingmap.sg/wordpress/wp-content/uploads/Braddell-View.jpg)](https://www.housingmap.sg/hudc/) ###### [List of HUDC estates](https://www.housingmap.sg/hudc/) [![executive condominium](https://www.housingmap.sg/wordpress/wp-content/uploads/condominium.jpg)](https://www.housingmap.sg/ec/) ###### [List of Executive Condos](https://www.housingmap.sg/ec/) [![Singapore MRT and LRT map](https://www.housingmap.sg/wordpress/wp-content/uploads/Singapore_MRT_and_LRT_System_Map-da8abf.svg)](https://www.housingmap.sg/mrt/) ###### [List of MRT and LRT stations](https://www.housingmap.sg/mrt/) ### 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. buy HDB loan, season parking, rental ## 1 comments about Home Page 1. ![](https://secure.gravatar.com/avatar/7b024467d41591ddfbb28ed00fd8140060ac79ab6d13e9fc3705436cb0a1bdea?s=50&d=mm&r=g) [happy horse ai](https://happyhorse-ai.co/) [April 10, 2026 at 8:17 am](https://www.housingmap.sg/#comment-22420) [Reply](https://www.housingmap.sg/#comment-22420) thanks share ## Leave a comment [Cancel reply](https://www.housingmap.sg/#respond) ### FAQ ##### Can you provide additional info?

Interactive map created in 2017. In 2018 I added floor plans from most popular old blocks. By 2021 96% of 1960-1991 blocks and 62% of 1991-2005 blocks had at least 1 floor plan. In the past a floor plan was applicable 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 applicable 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\! ## 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](https://homes.hdb.gov.sg/home/landing). Once they are launched, you can see BTO name, 3D render, number of flats, prices and floor plans, but 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](https://www.housingmap.sg/bto/#brochures).

into an [Excel file](https://www.teoalida.com/database/HDB-Key-Statistics-by-Teoalida.xlsx) and generated the below charts. Use keys ↑↓ to navigate through years and see town evolution. Read more: <https://www.housingmap.sg/hdb-statistics/> Values Percentage ## HDB price trends HDB Resale Price Index DOUBLED from 2007 to 2013 due to low construction, dropped 10% to 2015 then stabilized until 2020 when COVID-19 pandemic triggered another bubble. The growth slowed down as 2025 but the future remains uncertain as Singapore economy is influenced by external factors (Ukraine war, US-China trade war, etc). However the price trends were NOT similar across towns and block age. Read more <https://www.housingmap.sg/hdb-prices/> ## Need bulk data for analysis? Beside this, I made very detailed [HDB Blocks Database](https://www.housingmap.sg/hdb-database/) 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. [![HDB Database](https://www.housingmap.sg/data/HDB-Database.png)](https://www.housingmap.sg/hdb-database/) ## Flat types (most popular 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. \| Most popular floor plans \| Flat type \| Year built \| Notes \| \|---\|---\|---\|---\|

\| 3gen flat \| 115 sqm (introduced in 2013 BTO, completed 2017-present) \| 4 bedrooms, 3 toilets, home ownership restricted for couples + 1 additional family relative \| ### 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](https://www.housingmap.sg/hdb-floor-plans/HDB-1989-1991-4A-corridor.png)), while some 5-Room Improved from same period had only 3 (but big) bedrooms and a living room ([example](https://www.housingmap.sg/hdb-floor-plans/HDB-1984-1988-5I-corridor-end-120sqm.png)). 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. buy HDB loan, season parking, rental
