TL;DR
- Estimate net usable area, gross leasable area, and seat count for any Class A office requirement.
- Adjust for headcount, work style (in-office vs. hybrid), meeting intensity, and amenity ambition.
- Returns low, recommended, and high bands plus a programme breakdown.
Methodology
Workstations are sized by work-style ratio; meeting rooms scale with meeting intensity; amenity zones scale with the chosen ambition level. A market-typical loss factor (15–28%) is applied to convert net usable to gross leasable area.
How to use it
- Enter headcount — Provide expected on-site headcount and any growth buffer for the lease term.
- Pick a layout density — Choose between dense, balanced, or generous workspace ratios per persona.
- Add support spaces — Layer in meeting rooms, phone booths, collaboration zones, and amenities.
- Review the breakdown — Get net usable square feet, loss-factor-adjusted leasable area, and a seat-mix summary.
Frequently asked questions
- What headcount should I plan for?
- Use peak on-site occupancy. Most Class A occupiers plan for 60–80% of total staff present on any given day.
- Is the loss factor included?
- Yes — gross leasable area applies a market-typical loss factor (15–28% by city).
- Does it support hybrid schedules?
- Yes. Lower density slider models neighborhood-style hot-desking or shared seats.
