HDB Build-To-Order (BTO) Flats

[Update: Some BTO projects may be delayed by up to 6 months due to the coronavirus outbreak, according to an announcement by HDB in late-May 2020.]

Build-To-Order (BTO) is one of the modes of sale of new HDB BTO flats in Singapore. A HDB BTO sales launch takes place quarterly and typically offers a range of flat types across a few estates.

This system offers the applicant flexibility in location and timing when applying for his/her new flat. Construction will only begin if the demand for the number of apartments in a specific contract exceeds 70%.

A waiting period of about 3-4 years is usually required since flats are built upon order. This page serves the purpose of providing information only. To purchase a BTO, click here to visit HDB’s website.

Upcoming HDB BTO Launch — Aug 2021

The upcoming HDB BTO sales launch will be in Aug 2021. For the Aug 2021 launch, new flats will be offered at the following estates:

EstateFlat TypeUnits Available
Hougang2-room Flexi, 3-room, 4-room, 5-room1,320
Jurong East2-room Flexi, 3-room, 4-room560
Kallang/Whampoa3-room, 4-room300
Queenstown3-room, 4-room610
Tampines2-room Flexi, 3-room, 4-room, 5-room2,140

Note that the projects in the different estates may offer different flat types. For example, if you have a larger family and are looking for a more spacious 5-room BTO flat, not all of the projects may offer it. Likewise, if you want a smaller, more affordable 3-room BTO flat, some of the mature estates may not have it in the unit mix. The most common – but also most popular – flat type is the 4-room BTO flat.

HDB implements a policy known as the Ethnic Integration Policy (EIP) to ensure a good mix of households from different ethnic groups. The quota is revised on the 1st of every month, but may be generalized to the following approximate percentages:

85% Chinese, 22% Malay and 13% Indian and Other Households.

Applicants may check their eligibility here for buying into a particular block.

Although Hougang is a non-mature estate, it is well developed and residents can enjoy convenient access to many amenities such as key transport nodes, shopping malls, parks, healthcare facilities and more.

Additionally, families may want to note that there are also many popular schools in the area, including Maris Stella High (Primary and Secondary) and Paya Lebar Methodist Girls’ School (Primary and Secondary).

This Jurong East BTO will be located along Toh Guan Road, where an upcoming Toh Guan MRT station is also under construction (Jurong Region Line). For now, the nearest major transport node is Jurong East MRT, about 10 minutes away by bus.

Jurong East is a non-mature estate, but like Hougang, boasts many of benefits of mature estates. For starters, there is a cluster of malls and amenities near the Jurong East MRT station area, including JEM, Westgate, JCube and IMM. Healthcare facilities Ng Teng Fong General Hospital and Jurong Community Hospital are also in the area.

For nature lovers, the newly revamped Jurong Lake Gardens (Chinese Garden and Japanese Garden) are not too far away either.

This is the first time in 10 years there is a BTO launch in Jurong East, so if you’ve been eyeing a home in the area, you may want to try your luck. The Government has also announced plans to transform the Jurong Lake District so residents can also expect more job opportunities in the area.

In every HDB BTO launch, projects in the Kallang/Whampoa estate are always highly popular. This time, the new flats will be along Towner Road, in a very accessible city fringe location.

The flats will be just six minutes away from Boon Keng MRT by foot. Bendemeer and Farrer Park MRT stations will also be a short bus ride away. This means easy access to both the Downtown Line and North East Line.

While there are no modern, mega malls in the area, there is City Square Mall and Mustafa Centre to serve residents’ retail and daily needs. The flats will also be close to Kallang Polyclinic (10-minute walk) and Farrer Park Hospital (one MRT stop away).

These Queenstown BTO flats are also expected to be hot in demand in the August 2021 launch – this city fringe location is wildly popular, and the last time we saw a BTO launch here was nine years ago in 2012.

This batch of flats will be along Queensway, a few streets away from Queenstown MRT station, Queenstown Swimming Complex and Stadium and Queenstown Polyclinic. These will be about 10 minutes away by foot.

Additionally, there is the famous IKEA Alexandra nearby. Other retail options include Anchorpoint Shopping Centre and Queensway Shopping Centre. These are all only five minutes away!

In terms of nearby schools, choices are limited, but the popular Crescent Girls’ School is about 25 minutes away by bus.

Although there are two Tampines BTO flat locations to be offered in August 2021, they are just across the road from each other. They will both be along Bedok Reservoir Road and Tampines Street 96. The nearest MRT station will be Tampines West MRT, about 10 minutes away by foot.

These Tampines BTO flats are expected to be popular among nature lovers: not only is there a proposed park between the flats and Bedok Canal, but the blocks are also very close to Bedok Reservoir and may offer waterfront views, depending on the unit you eventually choose.

Residents will also be close to the main hub of activity around Tampines MRT station, which is 15-minute bus ride away. With the cluster of malls that comprise Tampines 1, Century Square and Tampines Mall, residents will be spoilt for choice when it comes to dining and shopping options.

For families with teenage children, there are also many Secondary and tertiary education institutions in the vicinity.
