RC homes in Osaka

In Osaka, an RC home runs about ¥1.2–1.9 million per tsubo (≈ ¥360k–570k per m²), main construction, ex-tax — roughly 1.5–2× timber (¥0.7–1.2M). Tsubo rates vary widely depending on whether they cover only the main build, site and utility works, or design and financing fees, so compare quotes on the same scope.

Guide rates run RC ¥1.2–1.9M and wood ¥700k–1.2M per tsubo (shell, pre-tax). RC wins on seismic, fire and lifespan; wood on cost, timeline and humidity control — at the estate level, decide by facade design × location × budget.

A soil survey (SWS or boring) decides the need; methods run from surface treatment to columnar mixing to steel piles. Detached-home guide: several hundred thousand to over ¥2M. Osaka's soft alluvial ground makes heavy RC homes the most exposed.
