Singapore office space planning FAQs
For practical office planning in Singapore, 110-140 square feet per person is the industry standard range. This isn't a regulatory requirement, but rather a guideline from workplace design best practices and industry benchmarking.
Why 110-140 sqft works:
- Industry benchmarks — real estate firms like CBRE and JLL consistently report this range across modern Singapore offices
- Workplace efficiency — balances personal workspace with shared amenities (meeting rooms, collaboration areas)
- Modern office trends — reflects open-plan layouts and flexible working arrangements
- Total usable space — accounts for circulation, shelves, and support areas beyond just desk space
Your specific needs may vary based on:
- Industry type and work style requirements
- Office layout preference (private offices vs open plan)
- Meeting room and collaboration space needs
- Growth projections and hybrid WFH flexibility requirements
Use our space calculator to get precise requirements for your team size and workspace needs.
Important context: Singapore's Fire Code uses 107.6 square feet per person for safety calculations, but this is for maximum occupancy and evacuation planning — not workplace design.
Office space calculators analyse multiple factors to estimate your total space requirements:
- Headcount analysis — current team size plus growth projections
- Workspace breakdown — workstations, meeting rooms, collaboration areas
- Circulation space — hallways, reception, break areas (typically 12-20% of total)
- Local regulations — Singapore's SCDF occupancy requirements
- Industry standards — space allocation norms for your business type
Advanced calculators also estimate rental costs (based on building grade) and renovation costs (from essentials only renovations to premium finishes), giving you a complete picture of your office investment.
To get accurate results from an office space calculator, gather this information first:
- Current headcount — full-time employees who need desk space
- Growth projections — planned hiring over the next 2-3 years
- Work style preferences — open plan vs private offices
- Special requirements — server rooms, reception areas, phone booths
The more specific your inputs, the more accurate your space and cost estimates will be.
Budget for these essential costs when planning your Singapore office space:
Monthly recurring costs:
- Rental — S$1.81-14.57 psf depending on building grade and location
One-time setup costs:
- Rental deposit — typically 3-6 months rent
- Renovation costs — S$130-160+ psf depending on renovation level
- Professional fees — legal, building's authorised QP, and renovation permit deposit
- Furniture and equipment — workstations, meeting room setups
Exit costs:
- Reinstatement — S$20-45 psf to restore original condition
