Planning model: 30-tsubo building
Because a station area contains multiple zoning districts, 60% building coverage and 150% floor-area ratio are comparison assumptions, not site regulations. The simple floor-area-ratio ceiling for a 30-tsubo lot is about 45 tsubo. The selected model is within this simple ceiling, but road, setback, height and other rules are not included.

Ancillary costs are provisionally set at 10% of construction cost. Public transaction records are retained; selection only changes which records are used for this estimate.
