Frequently Asked Questions
How accurate is this renovation cost calculator?
The estimates are based on real Singapore renovation market data for 2025, broken down by property type, room type, flat size, and design style complexity. They provide realistic ranges for budgeting — always get at least 3 contractor quotations for exact pricing.
What is included in the renovation cost estimate?
The estimate covers carpentry and built-ins, tiling and flooring, painting and finishing, electrical and plumbing, and furniture and decor. It does not include structural hacking, aircon installation, or appliance purchases.
Why does a resale HDB cost more to renovate than a BTO?
Resale HDB flats typically require additional hacking and rectification work to remove the previous owner's built-ins and finishes. BTO units start from bare condition, so there is no demolition cost.
Which design style is the most affordable for HDB renovation?
Muji Minimalist and Korean Minimalist styles tend to be the most affordable due to their emphasis on simplicity and clean lines. Ornate styles like Peranakan and Art Deco cost more due to detailed carpentry and custom finishing.
