How we chose the best interior design firms in Singapore
Our editorial team shortlisted established Singapore providers and compared them on reputation across public reviews, years in operation, range of services, pricing transparency and recognised accreditations or licences. Businesses marked Featured partner have paid for an enhanced placement; see our advertising disclosure.
A strong interior designer balances aesthetics, function and budget, and manages the project so you do not have to. We rank interior design firms on portfolio quality, design process, budget discipline, accreditation and how well they communicate through the project.
What to look for when choosing interior design firms in Singapore
- Review completed projects, not just 3D renders, and ask to speak with a past client if possible.
- Agree on a firm budget at the start and ask the designer to flag any variation orders in writing before work proceeds.
- Understand how the firm charges: design fee, percentage of project cost or included in a package.
- Ask who your day-to-day contact will be once works begin.
Licensing check: For HDB flats, the firm carrying out works must be listed in HDB's Directory of Renovation Contractors. CaseTrust accreditation is a common additional trust mark for interior design firms.
FAQs about interior design firms in Singapore
How much does an interior designer cost in Singapore?
Many firms bundle design into the renovation package, while others charge a separate design fee. Overall project costs depend heavily on carpentry, flat type and finishes.
When should I engage an interior designer for my BTO?
Start meeting designers a few months before key collection so you have time to compare proposals and finalise designs.
What is a variation order?
A variation order is a change to the agreed scope that adds or removes cost. Insist that every variation is quoted and approved by you in writing.
