How to interpret these values

Landform describes regional terrain, not the safety of an individual plot. Terraces are generally higher than surrounding lowlands; valleys and lowlands can collect water. Check local depressions, fill, drainage and official flood maps separately.

The sampled elevation range around Machiya is about 5.5 m. Absolute elevation alone does not determine flood risk. Slopes may affect access, retaining walls and rainwater flow.

AVS30 indicates average ground stiffness to 30 m depth. A larger value generally indicates stiffer ground. An amplification factor above 1 indicates estimated amplification of shaking, not a building’s seismic performance or a requirement for ground improvement.

Check disclosure documents, current municipal hazard maps and plot-specific ground investigations. Conditions can vary within the same neighborhood.

Estimate the land and building budget

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.

Planning model: 100.0 m² building
The simple floor-area-ratio ceiling for a 100.0 m² lot is about 300.0 m². 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.
