Office interior design Singapore
The Singapore office interior design market splits along three axes: design-build vs design-only, BCA licence class, and sector specialty. This page maps the landscape, lists notable firms by category, and matches you with the right specialist for your project.
What “office interior design” covers in Singapore
In Singapore, “office interior design” covers four overlapping deliverables. Understanding the difference is the difference between a firm that can take your project from concept to handover and a firm that produces drawings and walks away.
- 01Concept design — brief discovery, space planning, mood boards, finish palette. Design-only firms stop here.
- 02Detailed design — technical drawings, M&E coordination, FF&E spec, BCA / SCDF submissions. Design-only firms can do this in partnership with a contractor.
- 03Procurement & build — tender management, contractor appointment, site supervision, handover. Requires a BCA-licensed contractor.
- 04Furniture & styling — FF&E selection, dealer relationships (Steelcase, Herman Miller, Vitra), artwork, plants.
Design-build firms do all four under one contract. Design-only firms do 1–2 (and sometimes 4) and partner with a BCA contractor for 3.

What to include in your brief
The single biggest predictor of a smooth interior design engagement is the quality of the tenant’s brief. Include:
- ✓Headcount today + 3-year plan. Density assumptions drive the space plan.
- ✓Workstyle ratio. Open vs cellular; collaborative vs heads-down; in-office days per week.
- ✓Meeting room mix. 2-pax phone booth count; 4-pax huddle; 8-pax meeting; 20-pax town hall.
- ✓Brand expression level. Functional neutral vs sector-recognisable vs flagship statement.
- ✓Budget bracket. Per-sqft target. Honest is better than aspirational.
- ✓Programme. Move-in date is the constraint; design-build sequence backwards.
- ✓Special requirements. Server room, trading floor, lab, private wellness, parents’ room, Mandai-style biophilia.
