Question 1

How much does it cost to renovate an HDB flat in Singapore in 2026?

Accepted Answer

In 2026, a standard HDB BTO renovation in Singapore costs S$25,000–$45,000 for a 3-room flat and S$45,000–$70,000 for a 5-room flat at a modern style level. HDB resale renovations typically run 25% higher due to hacking, plumbing upgrades, and concealed wiring works.

Question 2

What is the most expensive part of a home renovation in Singapore?

Accepted Answer

Carpentry and built-in joinery is typically the largest variable cost in a Singapore renovation, ranging from S$8,000 to S$20,000 depending on scope. Kitchen renovations (S$8,000–$15,000) and bathrooms (S$4,000–$8,000 per unit) are the next largest items.

Question 3

How long does a full HDB renovation take in Singapore?

Accepted Answer

A full HDB BTO renovation typically takes 8–12 weeks from start to handover. Resale renovations take longer — usually 10–14 weeks — due to additional hacking and concealed works. Adding extensive carpentry or kitchen and bathroom works can extend the timeline by 2–4 weeks.

Question 4

Should I use an interior designer or contractor for my renovation?

Accepted Answer

An interior designer (ID) firm typically charges 15–20% more than a direct contractor but provides project management, 3D design, and a single point of accountability. For complex renovations with extensive carpentry or multiple wet works, an ID firm often saves time and reduces costly mistakes.
