How the calculation works
The model uses the ratios applied by space planners and flexible-office operators, in four building blocks:
Desks actually needed
With hybrid work, not everyone shows up at once — but peak days (Tue-Thu) size the requirement. At 3 office days per week, plan for roughly 75% of desks vs total headcount, hires included.
Surface per desk by layout
Dense open space runs around 8 sqm per desk, a mixed layout around 10 sqm, private rooms around 12 sqm. The Spanish market is roughly 15% denser than the French one.
Meeting rooms and phone booths
One meeting room (≈18 sqm) per 10 desks and one phone booth (≈2.5 sqm) per 8 desks: the ratio that avoids room wars without wasting surface.
Commons and circulation
Kitchen, lounge, corridors: from 15% (compact) to 35% (generous) of the work area. The most underestimated line in office briefs — and the main reason offices end up too small.
Frequently asked questions
How many square meters per workstation should I plan?
Market practice ranges from 8 sqm per desk in dense open space to 12 sqm with private rooms, shared areas included in the final total. The Spanish market runs about 15% denser. These ratios cover the desk itself; meeting rooms, booths and commons are added on top.
How does remote work reduce the surface needed?
The reduction is not proportional: even at 2-3 office days per week, attendance peaks (often Tue-Thu) force you to size above the average. At 3 office days, plan about 75% of desks; at 2 days, about 60%.
Is the calculator result binding?
No — it's an indicative range based on market practice. The actual surface depends on the building (floor depth, grid, pooled common areas). An operator always confirms the real capacity of a floor during a visit.
