Rule of thumbMandatory
Floor coverage accountability
LAY-COVERAGE-01Description
Every square foot of the floor's effective area must be assigned to a room or circulation; the sum of room areas must be within 5% of the effective area. Ground floor uses the footprint; upper floors use the rooms' bounding box (which may be smaller for stepped-back / cantilevered uppers).
Why this exists
Every square foot of the floor's effective area must be assigned to a room or circulation. Gaps mean unbuildable voids; overlaps mean rooms collide.
