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

  1. Enter headcount — Provide expected on-site headcount and any growth buffer for the lease term.
  2. Pick a layout density — Choose between dense, balanced, or generous workspace ratios per persona.
  3. Add support spaces — Layer in meeting rooms, phone booths, collaboration zones, and amenities.
  4. 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.
