Singapore Landed Construction Cost 2026: PSF Rates by House Type
What does it actually cost to build, A&A, or rebuild a landed home in Singapore in 2026? We compile the latest contractor benchmarks, BCA tender-price data, and 2026 market checks into one straight-talking cost guide for owners.
Singapore landed construction costs sit in an awkward middle ground. Higher than HDB upgrading. Lower than commercial high-rise. Often more variable than either, because landed plots vary in soil, access, and existing structure to a degree most other property types don’t.
The result: two visually identical houses on the same street can have 30% different construction budgets. We’ve quoted both ends of that spread. Below is what we see in the Singapore market in early 2026, plus the structural reasons cost varies and how to estimate reliably before you tender.
PSF Rates — The 2026 Cost Bands
Costs are quoted per square foot of Gross Floor Area (GFA), inclusive of structure, M&E, finishes, and main-contractor margin, but exclusive of QP fees, QS fees, demolition, and connection charges. All in Singapore Dollars.
| Project Type | Mid-Spec PSF | Premium PSF | Notes |
|---|---|---|---|
| New-build terrace | S$280–S$330 | S$380–S$500 | Mid-spec assumes ceramic tile, paint finishes, standard joinery |
| New-build semi-detached | S$300–S$380 | S$420–S$600 | Premium adds marble, smart home, designer joinery, lap pool |
| New-build detached / bungalow | S$320–S$420 | S$500–S$800 | Larger plot economies offset by basement / pool / landscaping |
| GCB-grade build | S$500–S$700 | S$800–S$1,200+ | Imported stone, lifts, wine rooms, deep basements, marine-grade landscaping |
| A&A (rear ext / attic) | S$200–S$280 | S$300–S$420 | Lower than new build, but contingency must be higher |
| Conservation shophouse | S$350–S$500 | S$550–S$900 | URA-compliant materials, heritage trades, longer schedule |
| Full demolition + rebuild | +S$30K–S$60K | +S$30K–S$80K | Demolition + disposal cost added to new-build psf |

What’s Inside the PSF Number
The headline psf rate covers structural shell (foundations, columns, beams, slabs), envelope (roof, external walls, windows, doors), wet trades (plaster, tile, screed), M&E (electrical, plumbing, ACMV), finishes (paint, joinery, sanitaryware), and main-contractor margin. Standard contingency is 8–12% of contract value held by the contractor.
The headline psf rate does not cover: Qualified Person fees (architectural QP plus structural P.E., typically 6–9% of contract value combined — see our Top 5 QPs guide for selection criteria); QS fees if you appoint an independent quantity surveyor like Yuhuang Estimating (1–3%); BCA / URA submission fees (S$2,000–S$8,000); utilities connection; landscaping / pool beyond standard inclusion; and FF&E (loose furniture, appliances, soft furnishings).
Why Costs Vary So Much
Three factors drive 80% of the spread between a low and a high quote on the same plot.
Finishes selection can swing total cost by 40%. The difference between mid-grade ceramic tile and Italian marble across all wet areas, kitchen, and feature walls is genuinely material. Smart-home installation, custom joinery, and high-end fixtures compound this further.
Structural complexity — basements, swimming pools, large cantilevers, double-volume spaces, and heritage element retention — carry disproportionate cost per psf because they require specialist trades, longer schedules, and more material per square foot. A basement on a Singapore landed plot, for example, often adds S$300K–S$600K for what looks like an extra 1,500 sqft of floor area but represents the most expensive 1,500 sqft of the project. CVC Engineers Pte Ltd — the structural P.E. firm we work with most often — can give you an honest pre-design view of what your envelope will cost before your architect locks the brief.
Site logistics — tight access roads (some Bukit Timah lots can’t take a 20-foot truck), neighbouring proximity (party-wall conditions on Joo Chiat shophouses), and soil conditions (peat-heavy plots in parts of Bukit Timah and Holland) — account for 5–15% of cost variation between visually similar properties. A site survey at concept stage by your structural P.E. catches this before tender.
How to Estimate Reliably Before Tendering
The single most reliable way to enter a tender with a credible budget: engage an independent quantity surveyor at concept-design stage. A pre-tender QS estimate based on your architect’s preliminary drawings gives you a defendable budget number, plus the Bill of Quantities that becomes the basis for apples-to-apples comparison when contractors quote.
We recommend Yuhuang Estimating Pte Ltd for landed and small-commercial projects. They produce milestone valuations during construction too, which keeps open-book contracts (like ours) honest on both sides.
Avoid the common mistake of estimating from psf rates alone. Two homes at S$350/psf can have wildly different total costs because GFA isn’t the same as constructed area — balconies, patios, basements, and accessory blocks may or may not be included depending on how your architect counts. The QS does this counting properly.
Hidden Costs to Plan For
- ▸Architect & engineer fees: 6–9% combined (QA + structural P.E.). Engage from Formspace Architects and CVC Engineers respectively.
- ▸QS fees: 1–3% if independent. Worth every dollar.
- ▸Submission fees: S$2,000–S$8,000 across BCA, URA, PUB, NEA depending on scope.
- ▸Demolition & disposal: S$30K–S$60K for a typical landed footprint.
- ▸Foreign-worker permits / dorm levy: Pass-through cost from contractor — ask for the breakdown.
- ▸Defect-rectification fund: Hold 5% of contract value for 12 months post-TOP. Standard.
- ▸FF&E: Loose furniture, appliances, soft furnishings. Budget separately. Easily S$50K–S$300K depending on spec.
Frequently Asked Questions
Questions we hear most often.
-
What is the construction cost per square foot for a Singapore landed home in 2026?
For a standard new-build terrace or semi-detached house in 2026, expect S$280–S$380 per square foot of GFA for mid-spec finishes, and S$400–S$700 per psf for premium specification. GCB-grade builds (with luxury finishes, smart home, lap pool, basement) typically run S$600–S$1,000+ per psf. A&A works are generally 15–25% cheaper per psf than new construction, but the savings are partially offset by hidden-condition contingencies. -
How much does an A&A cost for a Singapore landed home?
A typical landed-home A&A budget in 2026 runs S$300,000–S$1,500,000 depending on scope. A small rear-extension or attic conversion on a terrace is usually S$300K–S$600K. A full reconfiguration with a new floor added on a semi-detached runs S$700K–S$1.5M. A heritage-grade A&A on a GCB or conservation shophouse can exceed S$2M. Always hold a 10–15% client contingency for hidden conditions revealed during demolition. -
Should I do an A&A or a full rebuild?
Rule of thumb: if your structural envelope is sound and your reconfiguration intent is <40% of GFA, A&A wins on cost and timeline. If you’re changing more than half the layout, replacing the roof structure, or the existing building has settled or has serious water ingress, full rebuild is usually cheaper than fighting a problem-laden A&A. We have a separate brief on this decision — see Tear Down vs A&A: When to Rebuild Your Singapore Landed Home. -
Why do landed construction costs vary so much in Singapore?
Three main drivers. First, finishes — basic tile to luxury marble can swing total cost by 40%. Second, structural complexity — basements, swimming pools, large cantilevers, and heritage retention add disproportionate cost per psf. Third, site logistics — tight access roads, neighbouring proximity, and soil conditions (peat-heavy in some Bukit Timah plots) drive substantial cost variation between visually similar plots. -
How do I get a reliable cost estimate before tendering?
Engage an independent quantity surveyor (QS) like Yuhuang Estimating Pte Ltd at concept-design stage. A pre-tender QS estimate based on your architect’s preliminary drawings gives you a credible budget before contractors quote. It also produces the Bill of Quantities that becomes the basis for apples-to-apples tender comparison. Skipping this step is the most common reason landed projects blow their budgets. -
Are there hidden costs I should plan for?
Yes — QP fees (5–9% of contract value), QS fees (1–3%), URA & BCA submission fees (S$2,000–S$8,000), connection fees for utilities, ICA permit work-permit costs for foreign workers, professional indemnity gap if your QP under-insures, demolition disposal at LandTransport-approved sites, and post-TOP defect rectification fund (we recommend retaining 5% of contract value for 12 months).
