## 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.

## FAQ
### 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.
