The 7 Best Interior Designers in Singapore (2026)

Updated October 2026 · 7 picks

The best interior designers in Singapore in 2026 include Weiken, renovating homes since 1996 with CaseTrust Gold; Carpenters, with its own carpentry factory; Space Factor for luxury condo and landed homes; and Mr Shopper Studio for styled, bespoke interiors. For HDB flats, choose a firm on HDB's Directory of Renovation Contractors.

In Singapore an 'ID' (interior designer) usually means a design-and-build firm: it designs the space, then manages the contractors, carpentry and renovation through to handover. HDB flats can only be renovated by contractors on HDB's Directory of Renovation Contractors, and condos need the management's approval and a renovation deposit. Because renovation disputes are common, many homeowners choose firms accredited under CaseTrust-RCMA, which protects deposits.

Frequently asked questions

How much does a renovation cost in Singapore?

It depends far more on the scope than the firm. As a rough guide, a full renovation of a resale HDB flat often runs into the tens of thousands of dollars, a new BTO flat with built-in carpentry somewhat less, and condos and landed homes considerably more. Carpentry, hacking and rewiring drive the cost. Ask for an itemised quotation and compare like with like.

What is CaseTrust and why does it matter?

CaseTrust-RCMA is an accreditation scheme for renovation firms run by the Consumers Association of Singapore (CASE) with the Renovation Contractors and Materials Association (RCMA). Accredited firms use a standard renovation contract and protect your deposit with a deposit performance bond or insurance, which helps if a firm closes mid-job.

Do I need a permit to renovate an HDB flat?

Some works need an HDB renovation permit — such as hacking walls, replacing the bathroom floor or changing windows — and only a contractor on HDB's Directory of Renovation Contractors can apply for it and carry out the work. HDB also restricts noisy works to set hours. Your ID should handle the permit and tell you which works are not allowed.

How long does a renovation take?

A BTO flat with mostly carpentry commonly takes around 8 to 10 weeks; a resale flat with hacking, rewiring and new bathrooms often 10 to 14 weeks; condos and landed homes longer. Built-in carpentry made off-site is usually the longest lead item. Agree a timeline and progress-payment schedule in the contract.

Should I hire an interior designer or an architect?

For apartments and HDB flats, an interior designer. For rebuilding a landed house, extensions or structural changes that need URA and BCA approval, you need an architect. See our guide to the best architects in Singapore.
