Land area: above 0 to 100,000,000 m². Occupancy: 0–100%. Ratio: 0–100. Floors: 0–200 whole floors. Desired area: 0–100,000,000 m². Leave unknown values blank.

Footprint from occupancy assumption · m²
Not calculated: an assumption is missing or invalid.
Total floor area from ratio assumption · m²
Not calculated: an assumption is missing or invalid.
Total floor area from footprint × floors · m²
Not calculated: an assumption is missing or invalid.
Lower comparable total-area cap · m²
Not calculated: an assumption is missing or invalid.
Desired area minus comparable cap · m²
Not calculated: an assumption is missing or invalid.

Some constraints are missing. Partial figures must not be treated as a complete building envelope.

Footprint is ground coverage; total floor area adds floors. The model assumes comparable calculation bases and equal floor plates. Setbacks, excluded areas, height, slope, safety and design can reduce or prevent the project.
