Tokyo public survey used for the initial building-cost setting
FY2025, 393 land-attached custom homes; derived from an average construction cost of JPY 37.33M and average floor area of 104.8 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.
