A jumbo flat is an HDB unit of roughly 134 to 210 square metres, formed when HDB joined two adjacent flats into one. About 2,900 exist, most in Woodlands and Yishun, and almost all were built in the late 1980s or 1990s. That last point is the whole story for your wallet. You get 1,400 to 2,200 sqft for somewhere between the high-$700,000s and $1.3 million, huge value per square foot, but most carry only 55 to 65 years of lease left. This guide covers what jumbo flats cost in 2026, where they are, how the Conversion of Adjoining Flats Scheme works, and the lease-versus-price maths that tells you whether one is a bargain or a trap.
Jumbo flats are the largest HDB units you can buy, and they only exist on the resale market. HDB does not build new ones. They were created in 1989 to clear an oversupply of 3-room and 4-room flats: HDB knocked through the wall between two adjoining units and sold them as one. Today there are around 2,900 of them, concentrated heavily in Woodlands and Yishun, with smaller pockets in Tampines, Jurong East, Bedok, Hougang and a few mature estates.
In 2026 a jumbo flat typically transacts between the high-$700,000s and about $1.3 million, depending on town, floor, size and renovation. The space is the draw: 1,400 to 2,200 sqft, often with four or more bedrooms, two living areas and multiple bathrooms. The price per square foot is far lower than any new flat or condo of the same size. The catch is the lease. Built in the 1980s and 1990s, most jumbo flats now have only 55 to 65 years left on their 99-year lease, which limits who can buy, how much CPF you can use, and how easily you resell.
There is no single HDB flat type called jumbo. The term covers any unit formed by combining two adjacent flats. Most came from joining a 3-room with a 4-room, or two 3-room units. By comparison, a 5-room flat is around 110 sqm, an Executive flat around 130 sqm, and a 3Gen flat around 115 sqm. A jumbo flat starts where those stop and goes much higher.
Floor areas vary widely because the original pairs varied. Across estates, jumbo flats run from about 134 sqm in the smaller examples to over 200 sqm in places like Kallang/Whampoa and Tampines. A common size sits around 150 sqm, or roughly 1,600 sqft. Layouts are not standardised: you might get one wide flat with a single entrance, or a unit that still feels like two flats stitched together, with a doorway cut through the party wall. Always view in person, since the floor plan decides whether the extra space is usable or awkward.
Do not confuse a jumbo flat with a maisonette, an Executive flat, or a 3Gen flat. A maisonette is a double-storey unit; an Executive flat is a large single-type flat HDB designed as one; a 3Gen flat is a purpose-built four-bedroom unit. A jumbo flat is specifically two flats merged into one, and it shows up in resale listings under the Executive or jumbo label. Our maisonette guide covers that close cousin in full if you are weighing the two.
If you want space, a jumbo flat is one of four realistic options, and they trade off price, lease and layout very differently. A purpose-built Executive flat or maisonette is the closest match in floor area, but supply is just as thin and most carry similarly short leases. A 3Gen flat is the only large flat HDB still builds new, so it comes with a full 99-year lease, but it is smaller and sold under tight eligibility for multi-generation families. A resale condo of the same size gives you a longer lease and facilities, at two to three times the price plus monthly maintenance. The table below frames the choice.
Match the option to what you actually need. Buy a jumbo flat if raw space at a low price per square foot beats everything else and a shorter lease fits your timeline. Lean towards a 3Gen flat if a fresh lease and resale value matter more than maximum size. Step up to a condo only if you want the lease, the facilities and the upside, and you can fund the gap. The HDB versus condo comparison runs that last trade-off with numbers.
| Option | Typical size | Lease in 2026 | Rough price | Catch |
|---|---|---|---|---|
| Jumbo flat (resale) | 1,400 to 2,200 sqft | 55 to 65 years left | High-$700,000s to $1.3M | Short lease, thin supply, odd layouts |
| Executive flat / maisonette (resale) | 1,400 to 1,600 sqft | 55 to 70 years left | $800,000 to $1.3M | Also short lease, also resale only |
| 3Gen flat (new BTO) | About 1,200 sqft | Full 99 years | Subsidised BTO price | Smaller, strict multi-gen eligibility |
| Resale condo, same size | 1,400 to 2,200 sqft | Often 80+ years or freehold | 2 to 3 times a jumbo flat | Far pricier, monthly maintenance fee |
Geography matters because it drives both price and supply. The single biggest cluster is in the north. A large share of all jumbo flats sit in Woodlands, with Yishun the other major pocket, which is why these two towns dominate jumbo listings at any given time. That concentration exists because the 1989 conversion exercise targeted estates with the most unsold 3-room and 4-room stock, and Yishun was where the first batch launched.
Outside the north, you find scattered jumbo flats in Tampines, Jurong, Bedok, Hougang, Bukit Batok, Choa Chu Kang, Ang Mo Kio, Bishan, Toa Payoh, Queenstown, Bukit Merah, Clementi, Marine Parade and a handful of others. Units in mature, central estates are rarer and command higher prices. A jumbo flat in Queenstown or Marine Parade with good transport access sells for far more per square foot than one in Woodlands, even with a similar lease.
At any time only a few dozen jumbo flats are listed across the whole island, so this is a thin market. If you are set on a specific town, you may wait months for a suitable unit, and you have little room to negotiate when one appears. Track listings on the resale portals and set alerts rather than expecting to find one on demand.
| Estate | Floor area range (sqm) | Roughly (sqft) |
|---|---|---|
| Woodlands | 123 to 164 | 1,324 to 1,765 |
| Yishun | 128 to 163 | 1,378 to 1,755 |
| Tampines | 136 to 193 | 1,464 to 2,077 |
| Kallang/Whampoa | 118 to 210 | 1,270 to 2,260 |
| Jurong East | 134 to 168 | 1,442 to 1,808 |
| Bedok | 85 to 176 | 915 to 1,894 |
| Queenstown | 90 to 150 | 969 to 1,615 |
Prices have climbed with the wider resale market. The HDB Resale Price Index sat at 203.4 in the first quarter of 2026, edging down 0.1% from the previous quarter. That was the first quarterly dip in nearly seven years, after the index rose about 9.7% across 2024 and 2.9% across 2025. So the broad market has cooled, but the top end has not. A record 412 resale flats sold for $1 million or more in Q1 2026, up from 350 the previous quarter, and jumbo flats feature regularly in that million-dollar bracket because of their sheer size.
Two town records show the ceiling. In March 2026 a jumbo flat at 156 Tampines Street 12 sold for $1.21 million: 1,582 sqft with about 57 years of lease left, roughly $764 per square foot. In June 2025 a jumbo flat at Block 654 in Yishun's Nee Soon Central area sold for $1.28 million, a record for that town. Both were standout transactions, not the norm, but they mark where strong units in good locations can land.
For a more typical buy, expect the high-$700,000s to about $1 million. A Woodlands or Yishun jumbo flat with an average floor and renovation that needs work sits in the $780,000 to $900,000 range, while a higher floor, a central town, or a recently renovated unit pushes past $1 million. A resale condo of 1,600 sqft would cost two to three times as much, so the value per square foot is obvious. Run the numbers through our HDB loan calculator and stamp duty calculator, because the buyer's stamp duty alone on a $900,000 flat is over $21,000.
| Scenario | Typical price | Notes |
|---|---|---|
| Woodlands / Yishun, needs renovation | $780,000 to $900,000 | Most common, ~55 to 60 years lease |
| Higher floor or renovated, north | $900,000 to $1.05 million | Premium for condition and view |
| Mature / central estate | $1.0 million to $1.3 million | Tampines record $1.21M, Yishun $1.28M |
| Buyer's stamp duty on $900,000 | About $21,600 | Payable in cash or CPF on top of price |
This is the part that separates a smart jumbo buy from an expensive mistake. Almost every jumbo flat was built in the late 1980s or 1990s, so the 99-year lease is well into its second half. The Tampines record flat had about 57 years left. Many Woodlands and Yishun units are around 55 to 62 years. A shorter lease bites in three concrete ways.
First, financing. Once the lease falls short of covering the youngest buyer to age 95, the share of the flat you can pay with CPF starts to taper and your loan-to-value drops. If the remaining lease covers all buyers to 95, you can use CPF and borrow as normal; if not, you pay more in cash. Check your numbers with the CPF usage tool before you make an offer, since this can swing your cash outlay by tens of thousands.
Second, resale. When you sell in 10 or 20 years, the lease will be shorter still and the buyer pool narrower, with the same CPF limits hitting them harder. A flat with 40 years left is much harder to sell than one with 60. Third, the lease runs to zero. At the end of it the flat returns to the state with no compensation by default, so a jumbo flat is a depreciating asset on a clock, not land you own forever. None of this makes it a bad buy. It makes it a buy where you match the remaining lease to how long you plan to live there.
A practical check: take your age, add the years you plan to stay, and compare against the remaining lease. A 40-year-old planning to live there for life is well covered by 57 years. A 30-year-old couple buying their forever home should be wary of anything under 55 years, since they will outlive a chunk of the lease. Your CPF Ordinary Account funds most of the purchase, so the CPF lease rules directly shape what you can afford.
The lease drives the maths, but the standard loan and CPF rules set the frame. Two debt limits apply to any HDB purchase. The Mortgage Servicing Ratio caps your monthly home-loan instalment at 30% of gross monthly income, and the Total Debt Servicing Ratio caps all your monthly debt repayments combined at 55% of gross income. On a jumbo flat near the $1 million mark, the MSR is usually the binding limit, so a single income often will not stretch far enough on its own.
On loan size, an HDB concessionary loan lets you borrow up to 75% of the price or valuation, whichever is lower, leaving a 15% downpayment that you can pay in cash or from CPF. A bank loan also tops out at 75% loan-to-value for a first housing loan, but at least 5% of the price must be paid in cash. The HDB concessionary rate sits at 2.6% a year for the January to March 2026 period, pegged 0.1 point above the CPF Ordinary Account rate, while bank packages float with the market. Compare the two paths in our HDB loan versus bank loan guide before you decide.
Here is the jumbo-specific twist. How much CPF you can use depends on whether the remaining lease covers the youngest buyer to age 95. If it does, you can use your Ordinary Account up to the lower of the price or the valuation. If it does not, your CPF usage is pro-rated down by how far the lease falls short, and once every owner hits that pro-rated cap, no more OA can go in even if you still hold money there. A flat with under 20 years of lease left cannot use CPF at all. Most jumbo flats clear the 20-year floor comfortably, but plenty fall short of full coverage to 95 for a younger buyer, which quietly pushes more of the price into cash. Run your own figures through the CPF Housing Usage Calculator and our mortgage calculator before you commit, because the cash gap can run into tens of thousands.
| Rule | Limit | What it means for a jumbo buy |
|---|---|---|
| Mortgage Servicing Ratio (MSR) | 30% of gross monthly income | Usually the binding limit near $1M; often needs two incomes |
| Total Debt Servicing Ratio (TDSR) | 55% of gross monthly income | All debts combined, including car and card balances |
| HDB loan loan-to-value | Up to 75% of price or valuation | 15% downpayment, payable in cash or CPF |
| Bank loan loan-to-value | Up to 75% (first housing loan) | At least 5% of price must be cash |
| HDB concessionary rate | 2.6% a year (Jan to Mar 2026) | Pegged 0.1% above the CPF OA rate |
| Full CPF usage | Lease covers youngest buyer to 95 | Below that, CPF usage is pro-rated |
| No CPF usage | Lease under 20 years | Whole purchase funded in cash and loan |
The most common way to get a jumbo flat is to buy one that already exists, on the open resale market, like any other resale flat. The eligibility is the standard resale path: a valid HDB Flat Eligibility (HFE) letter, a family nucleus or eligible-single status, and a Singapore Citizen or Permanent Resident household that meets the rules. There is no special income ceiling to buy an ordinary resale flat, including a jumbo, unless you are claiming certain grants or buying a Plus or Prime flat, which jumbo flats are not.
Because a jumbo flat is classed for resale as an Executive-type or jumbo unit, first-timer families can still tap CPF Housing Grants, subject to the income ceiling for those grants. The Enhanced CPF Housing Grant and the Family Grant can knock a meaningful sum off the price, so do not assume a large flat means no help. Read our HDB grants guide and confirm your eligibility in the HFE letter, which tells you which grants and loan amount you qualify for before you start viewing.
Watch the cash-over-valuation gap. If a seller's price beats HDB's valuation, the difference is paid in cash on top of your downpayment, and on a sought-after jumbo flat that can run into five figures. Get the valuation after you have an Option to Purchase, and only commit to an offer you can fund. If you are torn between a roomy older jumbo flat and a smaller newer one, our BTO versus resale comparison lays out the trade-offs.
Budget for the renovation before you fall for the floor area. Most jumbo flats are 30-plus years old, so beyond cosmetic work you are often looking at hacking, rewiring, new plumbing and waterproofing across 1,400 to 2,200 sqft. That scale of work on a large old flat regularly runs into six figures, well above what a smaller resale flat would cost, and it is cash you spend on top of the purchase price. Size your budget early with our renovation cost calculator so the all-in number, not just the asking price, drives your decision.
The other route is to make a jumbo flat yourself by combining two adjoining units under HDB's Conversion of Adjoining Flats Scheme. This is far more restricted than most people expect, and it is the area where outdated guides get it wrong.
Only 3-room or smaller flats can be combined. You cannot join two 4-room or two 5-room flats into a jumbo, full stop. There are two scenarios. You either buy two adjoining 3-room-or-smaller flats at the same time, or you already own one and buy your next-door neighbour's 3-room-or-smaller flat. Either way you must form a family nucleus: a married couple, or a family of parents and children. Singles and joint singles cannot use this scheme. At least one buyer must be a Singapore Citizen aged 21 or above.
Before you commit, you must get HDB's confirmation that the specific flats are suitable for conversion. The structural work has firm rules. You must construct at least one opening of at least 1 metre by 2 metres between the two units, and you must remove the PUB meters from one of the flats so the combined unit runs on a single set of utility supplies. Once the two flats are joined, HDB treats the result as one unit, and you cannot split it back into two for sale or transfer later. That permanence matters: a future buyer is buying a one-off layout, not a standard flat type.
Buying two flats together on the open market means meeting the Ethnic Integration Policy and SPR quota for the block; buying your neighbour's flat next to your own does not. When you buy the adjoining flat to merge with one you already own, a fresh 5-year Minimum Occupation Period applies from the date the purchase completes, even if you have lived in your existing flat for years. If you take a CPF Housing Grant for the purchase, you become a second-timer and owe a resale levy based on the converted flat type when you next buy subsidised housing. You also have to redeem any outstanding HDB loan on your existing flat before taking a fresh loan for the adjoining unit, so line up your financing early. Buying two flats together can usually sit under a single loan, while buying the adjoining one to your existing flat needs a separate loan.
Treat it as a lifestyle-versus-asset decision. As a place to live, a jumbo flat is hard to beat on value. For under $1 million in many cases you get condo-sized space with no monthly maintenance fee, in established neighbourhoods with full amenities. A growing or multi-generation family that needs four-plus bedrooms and two living areas will struggle to match that anywhere else at the price.
As a wealth play, the maths is weaker. The short lease means the flat depreciates over your holding period, your future buyer faces tighter CPF rules, and the resale pool is small. You are unlikely to see the capital gain a younger flat or private property might deliver, and you should not buy one expecting to. If you would rather invest the difference, a cheaper flat plus a disciplined investing plan can leave you better off. Our rent-versus-buy calculator and the property guide help you frame that choice with your own numbers.
The buyers a jumbo flat suits best are clear: large families who value space over resale upside, and people in their 40s or older for whom a 55-to-60-year lease comfortably outlasts their plans. If you are young, planning to upgrade, or want an asset to leave behind, weigh the lease decay carefully before you fall for the square footage.
About 2,900 jumbo flats exist across the island. They were created from 1989 onward, when HDB combined two adjoining 3-room and 4-room flats to clear an oversupply. The largest concentrations are in Woodlands and Yishun, with smaller numbers in Tampines, Jurong, Bedok and other estates.
Most jumbo flats sell for between the high-$700,000s and about $1 million, with strong units in good locations going higher. In March 2026 a Tampines jumbo flat set a town record at $1.21 million, and in June 2025 a Yishun jumbo flat sold for $1.28 million. A typical Woodlands or Yishun unit needing renovation sits around $780,000 to $900,000.
Jumbo flats range from roughly 134 to 210 square metres, or about 1,442 to 2,260 square feet, with a common size around 150 sqm (1,600 sqft). They are larger than a 5-room flat (around 110 sqm) or an Executive flat (around 130 sqm), and usually have four or more bedrooms and two living areas.
Only if both flats are 3-room or smaller, and only as a married couple or a parents-and-children family. You either buy two adjoining small flats together or buy your next-door neighbour's small flat. You must get HDB's confirmation the flats are convertible first. Singles and joint singles cannot use the Conversion of Adjoining Flats Scheme, and 4-room and 5-room flats cannot be combined.
The lease. Almost all jumbo flats were built in the late 1980s or 1990s, so most have only 55 to 65 years left in 2026. A short lease limits how much CPF and loan you can use, shrinks your future buyer pool, and means the flat depreciates over time. Match the remaining lease to how long you plan to live there.
Usually yes, but the amount depends on the lease. If the remaining lease covers the youngest buyer to age 95, you can use CPF and borrow as normal. If it falls short, your CPF usage and loan-to-value taper, so you pay more in cash. Check your exact figures with the CPF usage tool before making an offer.
As a home, it is excellent value: condo-sized space for under $1 million in many cases. As an investment, it is weaker, because the short lease depreciates over your holding period and the resale market is thin. Buy one to live in, not to flip, and weigh it against a cheaper flat plus investing the difference.
Yes, a single can buy an existing jumbo flat on the resale market under the usual singles eligibility rules, since it is just a large resale flat. What singles cannot do is create one. The Conversion of Adjoining Flats Scheme is open only to married couples or parents-and-children families, so singles and joint singles cannot combine two flats themselves.
Expect a six-figure budget. Most jumbo flats are over 30 years old, so on top of cosmetic work you often need hacking, rewiring, new plumbing and waterproofing across 1,400 to 2,200 sqft. That scale of work on an old flat costs far more than a smaller resale unit, and it is cash spent on top of the purchase price. Price it with a renovation cost calculator before you commit.
An HDB loan covers up to 75% of the price or valuation, with a 15% downpayment payable in cash or CPF; a bank loan also tops out at 75% but needs at least 5% cash. Your monthly instalment cannot exceed 30% of gross income under the MSR. CPF use depends on the lease: full use needs the lease to cover the youngest buyer to age 95, otherwise it is pro-rated, and a lease under 20 years allows no CPF at all.
Both flats must be 3-room or smaller, and you must be a married couple or a parents-and-children family. You construct at least one opening of 1 metre by 2 metres between the units and remove the PUB meters from one flat. Once joined, the flat counts as a single unit and cannot be split for sale again. Buying your neighbour's flat starts a fresh 5-year MOP and may carry a resale levy.
