AI image by LocalRankChoosing among the many renovation contractors in Singapore means weighing accreditation, the property types a firm handles, and whether it manages design and building in-house. This guide profiles ten established interior design and renovation firms, from HDB and BTO specialists to studios that also take on condo, landed and commercial fit-out work. Each entry notes what the firm does and one point that sets it apart, drawn from the company's own website.
1. Weiken.com
Established in 1996, Weiken.com offers end-to-end interior design and renovation across HDB, BTO, condominium, landed and commercial spaces, covering space planning, material selection and project management. Its website lists CaseTrust and RCMA accreditation alongside ISO 45001 and bizSafe STAR certification. A full-service option for owners who want design and build handled by a single long-established firm.
2. Carpenters 匠
Carpenters pairs interior design with in-house carpentry, taking on HDB, condominium and landed homes as well as F&B, office and retail fit-outs. The firm's site states it has run since 2010, cites more than 13,000 completed projects, and lists CaseTrust-RCMA, HDB and BCA registration plus bizSAFE Level 3. Its craft-led, in-house joinery approach suits owners who prioritise built-in carpentry.
3. The Interior Lab
The Interior Lab is a residential and commercial interior design studio that handles HDB flats, condominiums and landed homes with a concept-driven, tailored approach. Its accreditations page lists CaseTrust accreditation, HDB and BCA registration, and bizSAFE Level 3. A design-led choice for homeowners who want the layout and finishes shaped closely around how they live.
4. Rezt+Relax Interior
Rezt+Relax has operated since 2000, delivering residential and commercial renovation that spans HDB, condominium and landed homes, including landed construction. Its site lists CaseTrust-RCMA and ISO accreditation, BCA certification, and Certified Renovation Professionals on its team. A long-established firm for owners whose scope covers both interior fit-out and heavier building work.
5. Swiss Interior
Founded in 2012, Swiss Interior provides interior design and home renovation for HDB flats (2-room Flexi through 5-room, BTO and resale), condominiums and landed homes. Its site states the firm is HDB-licensed and CaseTrust-accredited, with SIDAC accreditation and bizSafe Level 3, and it emphasises support that continues after handover. Suited to owners wanting a defined residential scope with post-completion service.
6. U-Home Interior Design
U-Home Interior Design has run since 1999, offering one-stop residential and commercial renovation for HDB flats, condominiums and commercial units. Its site lists CaseTrust and RCMA accreditation, HDB registration with a renovation licence, BCA accreditation and bizSafe 3. A broad, long-running option for owners who want design and build managed under one contract.
7. Ovon Design
Ovon Design works across residential HDB, condominium and landed projects as well as retail, hospitality and workplace interiors. Its website displays CaseTrust, RCMA, HDB and BCA accreditation together with bizSAFE certification. The firm positions itself for both home renovation and commercial fit-out, making it a candidate where a project spans the two.
8. Free Space Intent
Free Space Intent (FSI) is a full-service interior design firm operating since 1999, covering residential homes alongside bars, restaurants, retail outlets and offices. That mixed residential-and-commercial portfolio makes it worth considering for owners who also need F&B or retail fit-out. The firm describes a pared-back design approach built on clean lines and considered space planning.
9. Ciseern
Ciseern has operated since 1997, offering interior design, turnkey projects and a design-and-build service that runs from proposal and material selection through implementation and furnishing. Its portfolio spans HDB, condominium and landed residences. A turnkey-oriented pick for owners who prefer one team to manage the whole renovation rather than coordinating trades themselves.
10. Sky Creation
Sky Creation provides interior design and renovation for BTO, HDB, condominium and landed homes, keeping design, in-house carpentry and project coordination under one team. Its site highlights built-in furniture work and eco-conscious material choices as part of its renovation offering. Worth a look for owners who want carpentry and design kept in-house rather than outsourced.
How to choose
- Confirm the firm is HDB-registered before any HDB flat works, and check whether it holds CaseTrust or CaseTrust-RCMA accreditation, which adds a deposit performance bond.
- Match the firm to your property and scope: some concentrate on HDB and BTO homes, while others also handle condominium, landed or commercial fit-out.
- Ask whether design, carpentry and building are done in-house or subcontracted, and get a written, itemised quotation before you sign anything.
- Read the contract for the payment schedule, project timeline, how variation orders are handled, and the warranty on workmanship and carpentry.
- Verify licence and accreditation numbers on the official CaseTrust and HDB directories rather than relying on badges shown on marketing pages.
