One of the most consistent requests I hear from my high-net-worth buyers is deceptively simple: a large home, all on one floor, no stairs. No split-level entry, no mezzanine bedroom, no duplex configuration where the living room is on one storey and the master suite is on another. Just a generous, single-storey layout of 2,000 sqft or more, ideally in the Orchard precinct or the prime districts, where everything flows on a single plane.
It sounds straightforward. In practice, finding a true large-format, single-level home in Singapore's condo market is one of the harder briefs I work on. Here is why, where these homes do exist, and exactly what to look for before you commit.
Why Large Single-Level Condos Are Rare in Newer Developments
Singapore developers are commercially rational. On any given floor plate, splitting a large unit into a duplex or penthouse allows a developer to sell two storeys of space while occupying only one floor of the building's external footprint. That arithmetic is attractive. It also means that when you see a 2,500 sqft unit in a newer launch, there is a very real chance it is a duplex: the lower floor holds the living and dining areas, and a staircase leads to the bedrooms above.
Efficiency-driven layouts have become the norm since land prices rose sharply through the 2010s. Developers maximise gross floor area by stacking. The result is that genuinely large, single-floor apartments in newer condos are either rare or command a significant premium, typically as full-floor or near-full-floor units.
In my experience, buyers who have not specifically asked about this discover the duplex configuration only when they see the floor plan, sometimes well into the viewing process. I always check the floor plan before any site visit.
Where Single-Level Large-Format Homes Do Exist
There are four broad categories worth knowing.
- Older freehold developments in Districts 9, 10 and 11. Condos built in the 1980s and 1990s were designed with larger per-unit floor plates and less pressure to split vertically. You will find genuinely single-level apartments of 2,000 to 3,500 sqft in established freehold buildings in Orchard, Cairnhill, Holland Road, Bukit Timah and Newton. The trade-off is older fittings, a less contemporary common area, and sometimes lower ceilings. The freehold tenure and the single-level layout often make that trade-off worthwhile for the buyers I work with.
- Full-floor and near-full-floor units in luxury condos. In certain boutique luxury developments, one unit occupies an entire floor or the majority of it. These are genuinely single-level large floor plan condos with panoramic aspects and a high degree of privacy. They are rare, they move quietly, and they are rarely listed publicly at the moment the right buyer is looking. This is where knowing the market in advance matters.
- Good Class Bungalows and landed property. For buyers whose priority is a single-storey large home in Singapore and who are open to landed housing, a single-storey GCB or bungalow is the most direct answer. GCBs are restricted to Singapore Citizens. A single-storey landed home of 2,000 sqft and above on one floor is achievable but requires the right land size and configuration. Not all landed homes are single-storey, so the same scrutiny applies.
- Certain newer luxury condos with oversized single-floor plans. A small number of newer developments in the prime districts do offer large single-level units, typically at the higher floors and at price points that reflect their rarity. These tend to be 4-bedroom or 4-plus-study configurations where the developer has chosen to keep the unit on one floor rather than duplex it. They exist, but you need to know which buildings and which stacks.
How to Read a Floor Plan for Single-Level Confirmation
The floor plan is your primary tool. Here is what I look for and what I tell my clients to check.
- Look for a staircase symbol within the unit. Any internal staircase on the floor plan confirms a duplex or split-level layout. There is no ambiguity here.
- Check whether the unit spans more than one floor number. A duplex will typically be described as occupying, for example, floors 12 and 13. A single-level unit occupies one floor only.
- Verify the ceiling height on the plan or in the developer's specifications. Duplexes sometimes have double-volume living areas. A standard slab-to-slab height with no void confirms a single floor.
- Calculate the net liveable area versus the total strata area. Void spaces in duplexes inflate the strata area without adding usable floor space. On a single-level unit, almost all of the strata area is liveable.
- Ask specifically in writing. Ask the agent or developer to confirm in writing that the unit is entirely on one floor with no internal staircase and no split-level elements. This removes any ambiguity.
The Trade-Offs to Weigh
| Property Type | Single-Level Achievable? | Key Trade-Offs |
|---|---|---|
| Older freehold condo (D9/D10/D11) | Yes, commonly | Older fittings, potential MCST issues, lower ceilings in some buildings |
| Full-floor luxury condo unit | Yes | Very limited supply, high price quantum, rarely publicly listed |
| Newer launch large-format unit | Sometimes, verify carefully | Many are duplexes; single-level units at premium pricing |
| Landed / GCB (single storey) | Yes | GCBs restricted to Singapore Citizens; maintenance and security considerations |
What This Means for Your Budget and Stamp Duty
A genuine single-level large floor plan condo singapore buyers want, at 2,000 sqft and above in Districts 9, 10 or 11, will typically be priced from S$4 million upwards, often considerably more for a full-floor apartment or a newer luxury building. At that quantum, the stamp duty numbers are material.
Buyer's Stamp Duty (BSD) is calculated on a progressive scale. On a S$4 million property, the BSD runs to roughly S$150,000 or more, based on rates that reach 5% on the portion above S$1.5 million and 6% on the portion above S$3 million. Use the IRAS BSD calculator at iras.gov.sg for the precise figure on your intended purchase price, as rates and thresholds can be updated.
Additional Buyer's Stamp Duty (ABSD) is payable depending on your profile and how many residential properties you hold. Current rates as at 2026: Singapore Citizens pay 0% on a first property, 20% on a second, and 30% on a third or subsequent property. Permanent Residents pay 5% on a first property, 30% on a second, and 35% on subsequent properties. Foreigners pay 60%. Purchases via a living trust attract an ABSD (Trust) rate of 65%. These rates have changed with cooling measures before and may change again. Always confirm the current rate directly with IRAS before transacting.
Your loan eligibility is governed by the Total Debt Servicing Ratio, which caps total monthly debt obligations at 55% of gross monthly income. Banks stress-test your loan at a medium-term floor rate of around 4% per annum, not the promotional rate. The first housing loan is capped at 75% of the purchase price or valuation, whichever is lower, requiring a minimum 25% downpayment, with at least 5% in cash and up to 20% in CPF and/or cash. Confirm your specific loan position with your bank. For a fuller breakdown of the financial framework, see my guide on buying private property in Singapore.
Beyond the downpayment, budget separately for BSD and ABSD (both payable in cash upfront, with CPF reimbursement possible within limits), legal fees, and a financial buffer. On a S$5 million purchase, total transaction costs including stamp duty can add several hundred thousand dollars to your outlay.
Many of my buyers at this level also ask whether to buy under a trust structure. That is a separate conversation with meaningful legal and tax implications, and one I explore in detail in my guide on buying Singapore property under a trust.
My Perspective as Your Adviser
For the buyers I work with most closely, a large single-level layout is not a preference. It is a non-negotiable. Whether the reason is mobility, lifestyle, a strong aesthetic preference for uninterrupted horizontal space, or simply not wanting stairs in a home they plan to hold for decades, the requirement is real and the brief is specific.
What I find again and again is that the homes which meet this brief properly sit in a narrow part of the market: older freehold buildings in the Orchard precinct and surrounding prime districts, a handful of full-floor luxury units, and selected landed options. They are not always visibly available. Many of the best ones trade quietly, between buyers and agents who know they exist before they are ever listed.
If a single-level large floor plan condo is your priority, the most useful thing I can do is map the buildings that match your brief now, before you start viewing. That is a conversation worth having early.
