Office Space Benchmarks by Density Model
| Density Model | m² per person | ft² per person |
|---|---|---|
| Dense open-plan (hot-desking) | 8-10 | 86-108 |
| Standard open-plan (assigned) | 10-12 | 108-129 |
| Mixed (open + private offices) | 13-16 | 140-172 |
| Premium (large desks + breakout) | 18-22 | 194-237 |
| Legal / finance traditional | 20-30 | 215-323 |
What does the per-person figure include?
The benchmarks above are gross usable area per headcount. This typically includes: desk space (typically 6 m2 for a single desk), circulation space around desks (minimum 1.2 m clear passage per BCO guidance), a proportional share of meeting rooms (1 meeting room per 8-12 people), shared amenities (kitchen, reception, toilets). It does not include structural walls, mechanical rooms, or loading bays.
The BCO (British Council for Offices) 2023 Guide recommends 8-13 m2 per workstation for contemporary open-plan offices, acknowledging that post-pandemic hybrid working has reduced peak occupancy. Many tenants now plan for 60-70% desk utilisation, which effectively increases the per-desk space available.

International Commercial Units
Square feet remains the dominant unit in US commercial real estate. Office leases in New York, Chicago, and Los Angeles are almost universally quoted in sq ft, with a price in USD per sq ft per year. In Europe, square metres is standard, with rents quoted in euros or pounds per m2 per year (or per annum). Many global lease summaries show both. When comparing across markets, always confirm which unit applies and whether the figure is Net Internal Area (NIA), Gross Internal Area (GIA), or Gross External Area (GEA), as these can differ by 10-30%.
