An HDB renovation in Singapore typically costs about S$36,000 to S$82,000 for a BTO flat and S$51,000 to S$97,000 for a resale flat, based on Qanvast's published project data. Small refreshes such as painting start from about S$1,800. Flat size, new versus resale, the amount of built-in carpentry and kitchen or bathroom work change the total most.
The ranges below come from Qanvast's renovation cost guide (published January 2025, the latest full breakdown we could open) and from firms' own price pages, checked on 3 October 2026. Treat them as budgeting bands, not quotes.
How much does it cost to renovate an HDB flat?
Qanvast's 2025 figures put a 4-room BTO renovation at S$51,000 to S$61,800 and a 4-room resale renovation at S$64,300 to S$80,300. Bigger flats and older resale flats cost more because there is more floor area and often more to remove or repair.
| Flat type | BTO (new) | Resale |
|---|---|---|
| 3-room | S$36,100 to S$43,700 | S$51,000 to S$61,800 |
| 4-room | S$51,000 to S$61,800 | S$64,300 to S$80,300 |
| 5-room | S$67,000 to S$82,400 | S$84,300 to S$97,000 |
Source: Qanvast, "How Much is a 3, 4, and 5-Room HDB Flat Renovation in 2025?", based on a projected 2 to 3% rise from 2024 medians across 259 BTO and 302 resale projects. Qanvast's calculator page gives the same overall bands: S$36,000 to S$82,000 for BTO and S$51,000 to S$97,000 for resale.
Why does a resale flat cost more to renovate?
Resale flats usually need old fittings, tiles and carpentry removed before new work starts, and hidden damage often turns up. On Qanvast's bands, resale renovations cost about S$13,000 to S$18,000 more than BTO renovations for 3- and 4-room flats.
A BTO flat arrives with basic finishes, so owners can choose what to keep. FixMove's BTO guide shows how much that choice matters: a light package that keeps existing finishes runs S$15,000 to S$25,000, while a broader renovation with bathroom work and premium finishes runs S$42,000 to S$55,000.
How much do individual renovation jobs cost?
If you are not doing a full renovation, published bands start at about S$1,800 for a single room's paint and minor fixes. Kitchens and bathrooms are the costliest single areas: FixMove lists kitchen work at S$8,000 to S$18,000 and bathroom work at S$5,000 to S$9,000 for BTO flats.
| Scope (FixMove, 2026) | Published band |
|---|---|
| Single-room paint, patching, minor carpentry or tap swap | From S$1,800 |
| Small multi-room refresh | From S$3,800 |
| Full-flat paint with light carpentry, lighting and hardware | From S$6,800 |
| Single wet-area rebuild (kitchen or bathroom) | From S$9,800 |
| Kitchen and bathroom basic upgrade with flooring | From S$15,800 |
| Standard 4 to 5-room HDB renovation | From S$22,800 |
| Typical 4 to 5-room package with kitchen, bathroom, flooring and carpentry | From S$32,800 |
| Premium custom work | From S$48,800 |
| BTO carpentry only | From S$12,000 |
| BTO living room feature wall | S$1,500 to S$4,000 |
| BTO aircon system | S$3,000 to S$4,500 |
FixMove describes every figure as indicative and confirms final costs in writing before work begins.
What changes the cost of an HDB renovation?
Flat size and condition set the baseline. After that, built-in carpentry, kitchen and bathroom work, material grade and any rectification of hidden damage decide where in the range you land.
- Flat size. Qanvast notes a 5-room BTO renovation can cost S$30,000 more than a 3-room one.
- New or resale. Resale flats need more removal and repair work.
- Carpentry. Wardrobes, kitchen cabinets and feature walls add up quickly; FixMove prices BTO carpentry alone from S$12,000.
- Wet areas. Kitchens and bathrooms involve plumbing, waterproofing and tiling.
- Labour. Qanvast attributes recent cost increases mainly to fewer skilled workers since the pandemic, while material costs have stabilised.
How do I compare renovation quotes?
Ask each firm for an itemised quotation using the same floor plan and scope, so you compare like with like. Check what is excluded, how variations are priced and the payment schedule.
- Itemise carpentry by length and material, not as one lump sum.
- Confirm who handles HDB renovation permits for the works.
- Ask about accreditation, such as CaseTrust, and workmanship warranties.
- Keep a contingency for surprises, especially in resale flats, where FixMove notes hidden damage and rectification work can change the final price.
Which renovation firms publish their prices?
Few interior design firms publish package prices, because every flat differs. The firms below handle HDB renovations; where one does not publish prices, we say so.
