Renovation Cost Guide Singapore (2026): What You Should Really Budget

Why renovation quotes vary so much

Two quotes for the 'same' renovation can differ by tens of thousands of dollars. The difference is rarely the workmanship alone — it is the scope assumptions hidden inside each quote: how many coats of paint, what grade of plywood, whether debris disposal and permits are included.

As a direct contractor, we believe the fix is simple: itemised quotations. When every line is visible, you can compare fairly and cut what you do not need.

Typical cost ranges by property type

These ranges reflect common market spending for full renovations in Singapore. Your actual cost depends on scope, materials and site condition — treat these as orientation, not quotation.

• HDB BTO (new flat): roughly $30,000–$70,000 for a full renovation
• HDB resale: roughly $50,000–$100,000+, as hacking, rewiring and wet works add up
• Condominium: roughly $40,000–$120,000 depending on size and finish level
• Landed property: highly variable — typically $100,000 and upward for whole-house works

Where the money actually goes

Carpentry and wet works (bathrooms and kitchen) are usually the two largest line items, often consuming half the budget between them. Flooring, electrical, painting and ceiling works make up most of the rest.

The biggest savings rarely come from cheaper workmanship — they come from scope decisions: keeping a bathroom layout instead of moving pipes, overlaying flooring instead of hacking, or phasing carpentry.

How to budget safely

Set aside a 10–15% contingency above your quoted price for the unknowns that only appear once hacking starts — especially in resale flats. A transparent contractor will flag variations before doing them, but having buffer keeps decisions calm.
