Ibaraki public survey used for the initial building-cost setting
FY2025, 292 land-attached custom homes; derived from an average construction cost of JPY 36.92M and average floor area of 110.8 m².

The initial land and floor areas are each 100 m², adjustable in 1 m² steps. This is a comparison model, not the Japanese average or a guarantee of buildability. Displayed values are rounded; area calculations use unrounded conversions.

Planning model: 100.0 m² building
The simple floor-area-ratio ceiling for a 100.0 m² lot is about 80.0 m². 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.
