In short: Small or mid-sized offices under one contract: Office Empire or OSCA. Larger, design-led fit-outs: ID21, or Dezign Format for retail and showrooms. Regional or multinational offices: M Moser or Unispace. Small commercial spaces from a design studio: Space Atelier.
Which firm suits you depends on the size of your office and how much design input you need. For a small or mid-sized office fit-out or reinstatement under one contract, look at Office Empire and OSCA. For a larger or more design-led fit-out from an established local firm, look at ID21 and, for retail and showroom spaces, Dezign Format. For a regional headquarters or a multinational’s office, look at M Moser and Unispace. For a small commercial space from a designer-led studio, look at Space Atelier.
Search results for office renovation and commercial interior design in Singapore are dominated by a few firms’ own pages and by AI-generated answer pages. This guide groups seven firms by type, sets out what each one says on its own website, and explains how to choose.
How we chose
We started from firms that appear often when Singapore businesses search for office renovation or commercial interior design, then kept only those whose commercial work we could confirm on their own websites in October 2026. We looked at:
- Type of firm. SME design-and-build, established commercial fit-out firm, global workplace firm, or designer-led studio.
- Scope. Whether the firm states it handles design, construction, project management and reinstatement.
- Singapore presence. A Singapore office or studio on the firm’s own site.
- Price transparency. Whether the firm publishes any pricing.
We did not rank firms by awards, review scores or project counts, because we could not verify them, and we left out paid directories and firms whose websites we could not load. The list is grouped by type rather than ranked.
FYAdvisers is a free matching service for Singapore businesses. Firms do not pay to appear in this list, and we describe each one only from what it says on its own website.

How to choose
Start with your floor area and how much design input you need. A small or mid-sized office with a fixed move-in date usually suits a design-and-build firm. A larger or brand-led office may justify an established design firm. A regional headquarters suits a global workplace firm. If you want independent advice and competing bids, appoint a designer and tender the works.
Then ask every shortlisted firm the same questions:
- Can we see similar offices? Ask for completed projects of a similar size and building type.
- Who handles approvals? Ask who the qualified person is for SCDF and BCA submissions, and whether landlord or MCST submissions are included.
- What is excluded? Get provisional sums, exclusions and furniture shown separately.
- How are payments scheduled? Tie them to progress, not large upfront deposits.
- What happens after handover? Ask about the defects liability period and reinstatement at the end of your lease.
Our office renovation page covers approvals, cost benchmarks and red flags in more detail. Once you have moved in, see office cleaning.

Frequently asked questions
What types of office renovation company are there in Singapore?
Broadly three. Design-and-build firms that serve SMEs handle design, approvals and construction under one contract. Established commercial interior design firms take on larger fit-outs, often with their own project management and joinery teams. Global workplace firms combine workplace strategy, design and construction for regional headquarters and multinational offices. Some residential interior designers also take on small commercial spaces.
How much does an office renovation cost in Singapore?
It depends on floor area and specification. One firm on this list publishes ranges: when we checked in October 2026, Office Empire listed small office renovations at S$5,000 to S$30,000, medium at S$30,000 to S$80,000 and large at S$80,000 to S$200,000 or more. As a wider benchmark, Cushman & Wakefield's 2026 guide puts an average collaborative hybrid fit-out in Singapore at about S$180 per square foot. Ask every bidder to price the same scope.
Should I hire a design-and-build firm or a separate interior designer?
Design-and-build gives you one contract and one point of responsibility, which suits most small and mid-sized offices. Appointing a designer and then tendering the works to several contractors gives you independent advice and like-for-like bids, at the cost of more coordination and usually a longer timeline.
