Planning model: 30-tsubo building
The simple floor-area-ratio ceiling for a 30-tsubo lot is about 18 tsubo. The selected model exceeds this simple ceiling; the total is a comparison scenario, not a buildable-plan estimate.

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.
