A 5-room BTO flat gives a Singapore family about 110 sqm of internal floor area, roughly 113 sqm once you count the air-con ledge, laid out as three bedrooms, two bathrooms and a living-dining strip that is noticeably longer than a 4-room's. It is the largest standard new flat HDB still builds in volume, and in the February 2026 exercise the cheapest 5-room launched from S$439,000 before grants in Sembawang Voyage. This guide puts hard, dated 2026 numbers on what a 5-room costs, who qualifies, the S$14,000 income ceiling, the EHG grant that can knock up to S$120,000 off, and the resale gap that makes buying new the value play.
HDB counts flats by rooms, where each bedroom is a room and the living-dining area counts as one. A 5-room flat is therefore three bedrooms plus a living-dining space, the same bedroom count as a 4-room but with a bigger living area and, in most layouts, a study or extra utility nook. HDB's February 2026 sales annex lists the 5-room with an estimated floor area of 113 sqm and an internal floor area of 110 sqm, measured to the centre line of the wall, with the difference being the air-con ledge that sits outside.
Against a 4-room's roughly 90 sqm internal, a 5-room buys you about 20 extra square metres. That space mostly lands in the living-dining run and a more generous master, which is why families planning for two or more children, or for ageing parents who visit often, stretch for it. The bedroom count does not change, so do not read "5-room" as four bedrooms; if you need a true fourth bedroom under one roof, the 3Gen flat is the only new HDB type that delivers it.
Prices below come straight from HDB's February 2026 BTO supply and pricing annex and are indicative ranges before any grant, based on 99-year leases. The headline: 5-room flats showed up only in the two Standard (non-mature) Sembawang projects that exercise. None were offered in the Plus or Prime projects, which is the norm now because HDB skews larger flats toward outer towns where land is cheaper.
The lower end of each range is a low floor or less ideal stack; the upper end is a high floor with the better aspect. Sembawang Voyage offered 428 five-room units; Sembawang Deck offered 234. If a 5-room is non-negotiable for you, the practical read is that you will usually be choosing a non-mature estate and a longer wait, since both Sembawang projects carry estimated waiting times of 33 to 44 months.
| Project | Town | Internal area | Indicative price (before grants) | Units | Est. wait |
|---|---|---|---|---|---|
| Sembawang Voyage | Sembawang (Standard) | 110 sqm | S$439,000 - S$582,000 | 428 | 44 months |
| Sembawang Deck | Sembawang (Standard) | 110 sqm | S$479,000 - S$585,000 | 234 | 33 months |
Plus and Prime flats sit in choicer, more central locations and come with tighter rules: a 10-year minimum occupation period instead of five, a subsidy clawback on resale, and rental restrictions. HDB rarely puts 5-room flats in these tiers because the per-unit subsidy and land cost would push prices uncomfortably high. If you want a large flat in a central area new from HDB, the realistic route is a 4-room in Plus or Prime, or a 5-room resale flat.
HDB's own annex prints the resale comparables next to each new project, and the gap is stark. Near Sembawang Voyage and Sembawang Deck, transacted 5-room resale flats of a similar 113 to 116 sqm with about 94 years of lease left went for S$715,000 to S$820,000. The new 5-room in the same area started at S$439,000. Even before grants, a buyer who can wait for the build saves roughly S$250,000 to S$380,000 against buying the nearby resale equivalent.
The catch is time and certainty. A BTO with a 33 to 44 month wait means three to four years before keys, during which you rent or stay put, and you cannot pick your unit until the selection appointment. Resale gives you the keys and the exact unit now, at a premium. The trade is money versus immediacy, which is exactly the call our BTO vs resale comparison walks through. For 5-room buyers the math leans hard toward BTO, because the resale premium on large flats has run furthest of all.
A 5-room BTO follows the standard family eligibility rules, with no special carve-out for the larger size. You apply as a family nucleus, most commonly a couple, under a scheme such as the Public Scheme, and at least one applicant must be a Singapore Citizen with the other being a citizen or permanent resident. Singles cannot buy a 5-room new from HDB at all; the singles route under the Joint Singles or single-citizen schemes caps out at a 2-room Flexi in any location, so a solo buyer who wants a large flat is looking at resale.
The monthly household income ceiling to buy a 5-room flat new from HDB is S$14,000 for a couple or family, the same ceiling that applies to 4-room and larger flats. Before you can ballot, you need an HDB Flat Eligibility (HFE) letter, which checks your eligibility, grants and loan options in one go. Get it first; without it you cannot apply. Our HFE letter guide covers what documents to prepare and how long it takes.
First-timer families buying a 5-room BTO can claim the Enhanced CPF Housing Grant (EHG), worth up to S$120,000 since the August 2024 revision. It is tiered: the lower your average monthly household income over the 12 months before application, the bigger the grant, and it phases out at a household income of S$9,000 a month. So a family earning near the S$14,000 ceiling can buy a 5-room but will draw little or no EHG, while a household under S$9,000 can pull down a meaningful chunk.
Two conditions catch people out. At least one applicant must have worked continuously for the 12 months before the HFE application and still be working when it is submitted. The flat's remaining lease must also cover the youngest buyer to age 95, which is a non-issue for a 99-year BTO but matters if you later compare against an older resale flat. To see how a grant reshapes your real outlay and monthly repayment, run the figures through the BTO affordability calculator before you commit. Our HDB grants guide lists every grant you can stack.
Affordability for an HDB flat is governed by two caps. Under the Mortgage Servicing Ratio (MSR), your home-loan repayment cannot exceed 30% of gross monthly household income, and this applies whether you take an HDB loan or a bank loan. If you take a bank loan, the wider Total Debt Servicing Ratio (TDSR) also caps all your debt repayments at 55% of gross income. The MSR is usually the binding constraint for a flat purchase.
Put numbers on it. Take the lower-end Sembawang Voyage 5-room at S$439,000. With the standard 75% loan-to-value HDB loan, you borrow about S$329,000 and pay roughly S$110,000 as downpayment, which can come largely from CPF. At the current HDB concessionary rate of 2.6% over 25 years, the monthly repayment is roughly S$1,490, so the MSR 30% test needs gross household income of about S$4,970 a month. A top-of-range S$582,000 unit on the same terms repays around S$1,980 a month and needs about S$6,600 in gross income. Pressure-test your own figure with the HDB loan calculator rather than trusting a single benchmark; rates and your tenure move the answer.
| Flat price | Loan amount (75%) | Est. monthly repayment | Gross income needed (MSR 30%) |
|---|---|---|---|
| S$439,000 | about S$329,000 | about S$1,490 | about S$4,970 |
| S$510,000 | about S$382,500 | about S$1,735 | about S$5,780 |
| S$582,000 | about S$436,500 | about S$1,980 | about S$6,600 |
A Standard 5-room BTO carries a five-year Minimum Occupation Period (MOP) from key collection, during which you must live in it and cannot sell or rent out the whole flat. Once the MOP is up, the 5-room is one of the easier flats to sell, because it sits in the size most upgrading families want and the supply of new large flats is thin. That scarcity is also why 5-room resale prices have climbed hardest in mature towns.
The numbers show it. In Q1 2026, median 5-room resale prices crossed S$1 million in several central towns, reaching about S$1.1 million in Toa Payoh and S$1.09 million in Ang Mo Kio, even as HDB's overall Resale Price Index edged down for the first time since 2019. A buyer who books a 5-room BTO in a non-mature town today is buying the same flat type that commands those prices once mature. If you are weighing whether to later move to private property, the HDB vs condo comparison sets out the upgrade math.
A 5-room BTO flat has an internal floor area of about 110 sqm, which is roughly 1,184 sqft, or about 113 sqm once you include the air-con ledge. It holds three bedrooms and two bathrooms, with the extra space over a 4-room mostly going into a larger living-dining area.
In the February 2026 BTO exercise, 5-room flats were offered only in Sembawang and ranged from S$439,000 to S$585,000 before grants, on a 99-year lease. Prices vary by floor and project, and the figure drops further once you apply the Enhanced CPF Housing Grant if you qualify.
The monthly household income ceiling to buy a 5-room flat new from HDB is S$14,000 for a family. The income you actually need to service the loan depends on price and tenure: a S$439,000 unit on a 2.6%, 25-year HDB loan needs about S$4,970 in gross monthly income to pass the 30% Mortgage Servicing Ratio test.
No. Singles cannot buy a 5-room flat new from HDB. The singles route, whether the single-citizen scheme or Joint Singles, is limited to 2-room Flexi flats in any location. A single buyer who wants a 5-room must buy one on the resale market, where prices are far higher.
