How to read your estimate
The range is for reference only and may not be accurate for your home. It allows for typical differences in quantities and material choices, but only a professional interior designer can confirm the cost, after reviewing your floor plan and requirements and preparing an itemised quotation.
The market band comes from the Qanvast 2025 renovation cost guides. It is a third-party reference, not a Carpenters 匠 quotation, and its scope may differ from what you select here.

How accurate is this renovation cost calculator?
It gives a budget range based on typical quantities for your property type and the scope you select. Your actual quotation depends on your floor plan, measured quantities, material selections, site condition and approvals, so the range is for reference only and may not be accurate. Please consult a professional interior designer to confirm the cost of your renovation.
Where do the prices come from?
The calculator uses Carpenters 匠 unit rates for carpentry, wet works, electrical, plumbing, ceiling, painting and cleaning. The market band shown beside your estimate is a third-party reference from published Singapore renovation cost guides.
What is not included in the estimate?
Appliances, loose furniture, lighting fixtures, sanitary wares, curtains, air-conditioning, window and grille works, and HDB or MCST deposits are excluded. Prices are shown before GST.
Why does a resale flat cost more to renovate?
Resale homes often need existing finishes removed, more debris disposal, rewiring, new water pipes and waterproofing before new finishes go in. Select “Resale” and the relevant works to see how these items change the estimate.
