5-Room HDB BTO Renovation Cost in Singapore: What You'll Actually Pay (2026)
Prices checked October 2026 against the published price lists of 526 contractors listed on Homees, MOM's 2025 wage data and Qanvast's 2026 report. How we price →
A 5-room BTO is the largest standard HDB, so it sits at the top of the BTO cost range — more floor to cover, more rooms, more carpentry. For 2026, a full renovation typically runs **S$14,000–S$76,500**, and a premium build with extensive built-ins can reach **S$90,000+**. As a BTO it's still a blank slate, so you avoid the hacking and rewiring a resale needs.| Scope | Typical cost | What you get |
|---|---|---|
| Essentials | S$14,000 – S$24,000 | Flooring, basic carpentry, painting, lights — liveable |
| Standard | S$60,600 – S$76,500 | Full carpentry, kitchen + 2 baths, ceiling/lighting, aircon |
| Premium | S$76,500 – S$103,275+ | Designer finishes, extensive built-ins, smart home |
Where these come from: Essentials = published whole-home packages from contractors listed on Homees (Oct 2026); Standard = Qanvast's 2026 projection from its 2025 project medians; Premium = designer-led work above that band. Furniture, appliances and contingency are on top. How we price →
Quick answer: budget around S$60,600–S$76,500 for a comfortable mid-range 5-room BTO renovation in 2026, plus 10% contingency and a separate furniture-and-appliances budget of S$12,000–S$25,000.
Where the money goes — room by room
The extra floor area and the larger living/dining are what push a 5-room above a 4-room. Each space links to its full guide:
| Space | Typical cost | Detail |
|---|---|---|
| Kitchen | S$12,000 – S$20,000 | Usually the priciest room |
| Bathrooms ×2 | S$10,000 – S$16,000 | ~S$5,000–S$8,000 each |
| Bedrooms ×3 | S$11,000 – S$21,000 | Wardrobe-led; larger rooms than a 4-room |
| Living/dining | S$9,000 – S$15,000 | Bigger area = more flooring, feature wall, lighting |
| Aircon (System 4) | S$3,000 – S$4,800 | More fan coils for the extra rooms |
| Whole-flat painting | S$1,500 – S$3,000 | More wall and ceiling area |
Carpentry is the single biggest driver, and it scales with the flat — a 5-room simply has more wall to line with built-ins. That's where premium budgets balloon and where careful scoping saves the most.
Why a BTO is cheaper than a resale
A new 5-room BTO skips the costly works a resale needs:
- No hacking — nothing to strip out. (See hacking & demolition.)
- No rewiring — electrical is new and to standard. (See electrical works.)
- No waterproofing replacement — the bathroom membrane is fresh, and HDB blocks tile removal for 3 years anyway. (See waterproofing.)
The same 5-room costs 20–40% more as a resale. (See the 5-room resale guide.)
What actually moves your price
- Carpentry run — a 5-room's larger bedrooms and living area mean more foot-run of wardrobes, cabinetry and feature joinery, at roughly S$150–S$300 per foot.
- Material tier — quartz vs laminate countertop, engineered timber vs vinyl, branded vs builder-grade sanitaryware.
- Ceiling and lighting — full false ceilings with cove lighting across a bigger living/dining add S$3,000–S$5,000. (See false ceiling & lighting.)
- ID vs contractor — an interior designer typically adds 10–20%.
- Scope creep — adding built-ins after signing is the usual budget-buster.
Cost by BTO town
5-room BTOs are common in newer towns, where first-time-owner fit-outs dominate:
- Punggol, Tengah, Tampines North — full carpentry packages, feature walls, smart-home wiring. Browse pros in Punggol and Tampines.
- Mature-estate BTOs — owners often spec premium finishes given resale potential; see Bishan.
The per-trade rates are broadly island-wide; what varies is the scope owners choose.
Sample budget — standard 5-room BTO
- Kitchen ≈ S$15,000
- 2 bathrooms ≈ S$12,000
- 3 bedrooms (wardrobes, flooring) ≈ S$18,000
- Living/dining (flooring, feature wall, lighting) ≈ S$11,000
- Aircon System 4 ≈ S$3,800
- Painting + lighting + sundries ≈ S$3,500
- Subtotal ≈ S$63,000, plus 10% contingency (~S$6,300)
That lands most standard 5-room BTOs in the S$60,600–S$76,500 zone for works alone.
Renovation timeline
A clean 5-room BTO moves quickly with no hacking:
| Week | Stage |
|---|---|
| 1–2 | Carpentry templating, electrical/plumbing first-fix, masonry |
| 3–6 | Carpentry installation, tiling, false ceiling |
| 7–8 | Painting, flooring, lighting, sanitaryware |
| 9–11 | Aircon, defects rectification, handover and clean |
Most 5-room BTO renovations complete in 9–11 weeks — a touch longer than a 4-room because of the extra carpentry. Book 2–3 months ahead during peak BTO waves.
Financing your renovation
- Renovation loans are capped at the lower of 6× monthly income or S$30,000, typically over 1–5 years. For a S$60,000+ job, many owners combine a reno loan with savings.
- It's separate from your HDB housing loan and not payable by CPF.
- Pay by milestone — 10% deposit, progressive payments against completed stages, and a 5–10% retention released after defects are cleared.
The costs people forget
- GST (9%) — confirm it's included; on a S$60,000 job that's ~S$5,400.
- Contingency (10%) — keep it in reserve even for a BTO.
- Furniture & appliances — a 5-room needs more of everything; budget S$12,000–S$25,000 separately.
- HDB OCS components — if you took HDB's Optional Component Scheme flooring/sanitary fittings, don't double-budget.
- Carpentry creep — the bigger the flat, the faster built-ins add up.
HDB rules worth knowing
- 3-year tile rule — no removing bathroom/toilet tiles for 3 years from key collection.
- Licensed trades — plumbing by a PUB-licensed plumber, electrical by a Licensed Electrical Worker (LEW); use an HDB-licensed, CaseTrust-accredited contractor.
- Permits — your contractor applies for the HDB renovation permit; structural changes need a Professional Engineer (PE) endorsement.
- Permitted hours — noisy work Mon–Sat 9am–6pm; none on Sundays and public holidays.
- Timeline — about 9–11 weeks.
How to keep the bill sensible
- Scope carpentry to what you'll use — the biggest driver in a big flat.
- Overlay vinyl flooring — fast and affordable over a flat BTO base.
- Stage non-essentials — feature walls and fancy lighting can come later.
- Keep 10% contingency.
- Compare 3 itemised quotes and benchmark each room against its own guide.
