What a turnkey build costs in Singapore per square foot

Updated 4 November 2026

A turnkey build in Singapore, where one contractor plans, designs and constructs the house through to handover, is usually quoted per square foot (psf). Expect about S$300 to S$600 psf for a new-build semi-detached house and S$320 to S$800 psf for a detached house or bungalow.

Licence and what to check

Builders in Singapore need a licence under the Builders Licensing Scheme, administered by the Building and Construction Authority (BCA). The scheme sets minimum financial requirements by class: at least S$300,000 for a Class 1 general builder and at least S$25,000 for a Class 2 general or specialist builder. Ask to see the licence before you sign, and check that its class covers the size of your project.

Why quotes differ

Construction costs in Singapore are among the highest in Southeast Asia, and one 2026 industry forecast put cost inflation at about 5%, so ask how long a quote stays valid. The wall material, the floor area and the utilities you need (plumbing, electrical, ventilation and air conditioning) all change the price, so ask every seller to quote the same specification.

Season and the wet weather

Singapore is hot all year, with a wet and a dry season instead of winter, so building work runs through the year rather than stopping for a cold spell. Heavy rain slows outdoor stages such as foundations and roofing, so ask the contractor to build a weather allowance into the timetable and the deadline.

What to put in the request

Name the building type, the floor area in square feet or square metres, the wall material, the plot location and your area, for example Tampines, Jurong West, Woodlands or Ang Mo Kio. Add the stage of work you need (design, construction or finishing), the utilities involved, your deadline and your budget in S$, so each builder can quote the same scope.

BlaBlaPrice is free for buyers. You describe the project in your own words in a chat, and BlaBlaPrice's AI asks for missing details, then looks through sellers' websites and price lists in Singapore and shows the prices and businesses it found. Registered sellers reply in the chat with their offer, terms and delivery dates, and your contacts stay hidden until you choose to share them.
