BTO Renovation Cost in Singapore: 2026 Budget Guide
A new BTO flat is a blank slate, but it is rarely a cheap one. Here are the 2026 cost ranges by flat type, what is usually included and where budgets creep.

A BTO flat arrives with bare floors, no built-in storage and a kitchen that needs fitting out, so the renovation bill is a large part of your move-in cost. This guide sets out the BTO renovation cost ranges quoted in Singapore for 2026, explains what drives them and shows how to plan a budget that holds.
These are indicative ranges for a standard specification, drawn from the ranges Singapore renovation guides quote. Quotes vary by firm, scope and finishes, so use them to sanity-check, not as a quote.
BTO renovation cost by flat type
| Flat | Typical BTO renovation range |
|---|---|
| 3-room | S$30,000 to S$45,000 |
| 4-room | S$40,000 to S$55,000 |
| 5-room | S$45,000 to S$67,000 |
Our detailed guides show how these numbers break down for the 3-room and for 4-room versus 5-room flats. Resale flats usually cost more because of hacking and replacement work. See resale HDB hidden costs.
What a new BTO usually needs
- Flooring: BTOs come without finished floors in living and bedroom areas
- Carpentry: wardrobes, TV console, shoe cabinet, kitchen cabinets
- Electrical: additional points, lighting and wiring changes
- Painting: the whole flat
- Doors: the main door gate and internal doors in some cases
- Kitchen and bathrooms: fittings, tiling and waterproofing where required
Your scope depends on the BTO handover condition, so check what is already done before you quote.
Where the money goes
Carpentry is usually the biggest line, followed by flooring, then the kitchen and bathrooms. Electrical and painting are smaller, but they add up. For kitchen-specific numbers, see the HDB kitchen renovation cost and HDB bathroom renovation cost guides.
Why a BTO is a good time to plan carefully
A new flat has no old finishes to work around, so most of the budget goes into things you choose rather than things you must fix. That makes it easier to control, and also easier to overspend on extras. Decide your priorities before the showflat and sample visits, because attractive displays make upgrades feel small. A written budget that you check each time you approve a change keeps the total honest.
Where BTO budgets creep
- Custom carpentry. Floor-to-ceiling units look good and add up fast.
- Upgrading finishes midway. Each upgrade seems small.
- Appliances and furniture that were not in the quote.
- Timeline slips that mean paying rent while waiting.
- Variation orders after works start.
Hold back a buffer of about 10 to 15% for changes you did not plan.
How to build a realistic BTO budget
- List must-haves first, then nice-to-haves.
- Get an indicative range from our renovation cost calculator.
- Ask for quotes from two or three firms on the same brief.
- Compare line by line, as explained in reading a renovation quotation.
- Plan the timing with the BTO renovation timeline.
Check the rules and the firm
A registered contractor must file the HDB renovation permit, and there are rules on what you can remove and when work can happen. Read our HDB renovation permit and rules guide and check the firm's credentials before you pay. Then browse HDB interior designers to start comparing quotes.
