10 Top-Rated Workspace Design Agencies in Singapore

Singapore’s workspace design market splits into two lanes: global architecture giants with local registered architects, and boutique interior firms focused on landlord-approved fit-outs. All ten firms below hold current registration with the Singapore Board of Architects or the Interior Design Confederation of Singapore (IDCS) and have delivered projects in Raffles Place, Marina Bay, or the JTC industrial estates. Selection criteria here stay on measurable facts: average fit-out cost per sqft, BIM software used, Green Mark Platinum track records, and factual client portfolios.

1. Space Matrix

Singapore-headquartered firm with its own workplace strategy team. They run Revit BIM delivery for all projects above 10,000 sqft and maintain a proprietary post-occupancy evaluation (POE) survey system. For a 40,000 sqft tech office in Pasir Panjang, they delivered a fit-out at SGD 95/sqft in 14 weeks, including coordination with JTC’s infrastructure guidelines.

2. Gensler Singapore

Gensler’s Singapore studio in Marina One actively publishes occupancy analytics from their own workplace performance index. They use a mix of Rhino and Revit and hold BCG Green Mark GoldPlus for multiple projects announced via BCA’s records. Their experience with large single-tenant floors—up to 60,000 sqft in Guoco Tower—makes them the default for financial tenants needing extensive FRR (fire safety) coordination with SCDF.

3. Ministry of Design

Singapore boutique led by Colin Seah. Unlike large-scale shops, MOD operates lean with a 12-person design team and outsources construction supervision to licensed builders. Their workspace clients are mostly creative firms below 8,000 sqft, with a documented project in a conserved shophouse on Telok Ayer Street—demonstrating how they handle URA conservation authority approvals and deep floor plates without street-level loading docks.

4. Unispace

Unispace runs a fully integrated design-and-build model in Singapore, meaning their construction arm in Tuas controls cost and schedule, not an external contractor. They reported a 10-week fit-out for a 15,000 sqft client in Alexandria (a former logistics warehouse) using prefabricated walls assembled on-site to cut air-conditioning downtime. Their data on workplace density: they use their own “Occupancy Index” based on badge-swipes and meeting-room booking logs, applied at ClientEarth’s Singapore office.

5. IA Interior Architects

IA’s Singapore team manages corporate interiors only—they do no residential work. They operate a strong Revit standards library calibrated for Singapore’s BCA BIM requirements, specifically for projects requiring CORENET e-submission in 2024. They recently completed a 25,000 sqft cybersecurity tenant in One-North with a full Faraday cage meeting room, reflecting how they adapt to high-tech vertical M&E and EMC shielding needs.

6. Aedas Interiors

Aedas Interiors delivers what their parent architecture firm draws —they are the interior arm of Aedas. They integrate facade and interior design under one roof, important for plot-ratio-sensitive projects where a double-glazed facade cantilever attracts URA gross floor area penalties. In Singapore, their notable workspace work includes a 50,000 sqft commodity-trading office at One Raffles Quay, where they tracked acoustics attenuation for trading-floor noise to NRC values above 0.85.

7. DP Design

The interior division of DP Architects, and the only firm on this list that regularly completes both core-and-shell architecture and interior fit-out for the JTC and HDB commercial property portfolios. They handle mixed-use conversions where the interior team must work within 20-year-old structural grids, such as Paya Lebar Square. Their strength is standardising M&E below raised floors, validated through BCA’s Occupancy Permit compliance.

8. Munge Leung Singapore

Toronto-founded, but their Singapore studio at Duxton Hill has delivered hospitality-grade office fit-outs for private banks. They specialise in custom solid-surface joinery, sourced from workshops in JB and IsoKlang—not imported from Italy—at a reported factory turnover of 6 weeks. Expect cost-per-sqft from SGD 150 upwards, reflecting the finish-grade and artisan labour, not merely square footage.

9. The Inside Concept

A local high-residential firm that has since expanded to full-floor corporate work. They own their own steel-frame furniture line, manufactured in Senai, Johor, which aligns with Singapore’s Green Mark points for recyclable content. Their typical workspace project: 10,000 sqft law firms in Tanjong Pagar with high-security meeting room configurations, using Dutch doors and anti-glass walls controlling acoustic privacy.

10. DWP (Design Worldwide Partnership)

Australia-founded with a Singapore studio in the CBD-Williams Street corridor. DWP has a niche for low-energy office fit-outs guided by the Singapore Green Building Council’s Net Zero Carbon pathway. Their approach documents embodied-carbon supply chains: for a recent 18,000 sqft workspace, they reduced interior concrete usage by using steel-decking raised floors that eliminate under-screed, cutting floor depth by 150mm, which increased ceiling height in an old 3.9m-storey building.
