■ Average Cost of New Exterior Construction (2021–2025)

As a result of the survey, the average construction cost has been trending upward year after year, exceeding 2 million yen for the first time in 2025.

In addition to the soaring material prices since the Wood Shock, the rise in logistics and labor costs is clearly reflected in exterior construction expenses. It is evident that the conventional wisdom from several years ago—that an "exterior budget is 1 million yen"—is becoming difficult to apply in the current market environment.
