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

HDB renovation typically costs from around S$25,000 for a smaller 3-room flat to S$60,000–S$80,000 for a 4- or 5-room flat, depending on scope, materials, and whether it is a BTO or resale unit. Resale flats usually cost more because of hacking, rewiring, and replacing old fittings.

How long does an HDB renovation take?

Most HDB renovations take about 6 to 12 weeks. BTO flats are usually faster since they need less hacking, while older resale flats can take longer due to additional structural and plumbing work.

Do I need an HDB renovation permit?

Yes. Many renovation works — including hacking walls, floor finishes, and electrical changes — require an HDB permit, which a HDB-licensed renovation contractor applies for on your behalf. Always confirm permit requirements with HDB before starting.

What are the permitted HDB renovation hours?

According to HDB guidelines, general renovation work is allowed on weekdays and Saturdays during daytime hours, while noisy work such as hacking and drilling is more tightly restricted and not permitted on Sundays and public holidays. Confirm the latest hours with HDB.

Which interior design styles suit HDB flats?

Japandi, Scandinavian, Muji-minimalist, and modern contemporary styles are popular for HDB flats because their light palettes and clean lines make compact spaces feel larger and brighter.
