Collecting keys to your BTO is exciting — and the renovation decisions that follow can be overwhelming. This guide covers what first-time owners actually need to know.
Realistic BTO renovation costs (2026)
- 3-room flat: $25,000–$45,000
- 4-room flat: $30,000–$60,000
- 5-room flat: $35,000–$75,000
BTOs are cheaper to renovate than resale flats because there's nothing to hack or make good. The big cost drivers are carpentry (usually 40–50% of the budget), flooring and wet works.
Timeline: plan for 8–12 weeks
A typical BTO renovation runs: design and quotation (2–4 weeks before key collection), HDB permit application (1–2 weeks), hacking and masonry, electrical and plumbing, carpentry fabrication (3–5 weeks, often off-site), installation, painting and finishing. Book your firm 2–3 months before key collection to avoid the queue.
Permits you'll need
Your contractor must be HDB-registered. Permits are required for hacking walls, replacing floors in wet areas, and window or grille changes. A good ID firm handles all submissions for you — confirm this is included in the quote.
Choosing the right firm
Compare at least three quotes with the same brief, check reviews and completed-project counts, and confirm what's excluded (electrical points, plumbing relocation and disposal fees are common surprises). Or skip the legwork — get matched free with firms vetted for BTO work.
