Site Capacity & Product Mix Explorer

Test the development envelope, residential product mix and parking demand. All planning controls are user-entered assumptions, not verified entitlements.

Input guidance and saving

Coverage applies to developable land; FAR applies to gross site area. Product shares allocate net residential area. Unit counts round down and parking demand rounds up.

First visits open with illustrative example inputs. Replace these with your own evidence before relying on the outputs.

2. Residential product mix

Shares allocate net residential area, not unit counts. Each unit count is rounded down.

Site-area diagram: dark teal = maximum footprint; pale teal = remaining developable land; grey = excluded land. This is an area relationship, not a masterplan.

122 spaces required · 130 available · 8 surplus

Product	Units	Net area
One bedroom	40	3,000 m²
Two bedroom	50	6,000 m²
Three bedroom	16	2,880 m²

120 m² remains after rounding to whole units. Parking, setbacks, access, fire strategy, height and local area definitions need a separate planning review.

Calculation basis

Developable land = gross site × developable share. Footprint = developable land × coverage. GFA is the lower of footprint × floors and gross site × FAR. Net residential area = GFA × efficiency. Units are rounded down for each area allocation. Parking demand is rounded up after summing units × parking ratios.

Version 1.0 · Residential capacity only. All floors use the same footprint; non-residential uses, basements, site geometry and detailed layouts are not modelled.

Planning assumptions

Gross site: 10,000 m² · Developable: 80% · Coverage: 40% · Floors: 5 · Maximum FAR: 1.5 · Efficiency: 80%

Limiting control: FAR. Available parking: 130; balance: 8 spaces.

Product mix

One bedroom: 25% of net area · 75 m² per unit · 40 whole units · 1 spaces per unit.

Two bedroom: 50% of net area · 120 m² per unit · 50 whole units · 1 spaces per unit.

Three bedroom: 25% of net area · 180 m² per unit · 16 whole units · 2 spaces per unit.

Unallocated area after unit rounding: 120 m².

Basis and review

GFA = min(developable land × coverage × floors, gross site × FAR). Unit counts use net residential area and are rounded down. Review parking, setbacks, access, height and local area definitions separately. Capacity Explorer v1.0.
