What is the construction cost of detached residences in Japan in terms of unit price per square meter?
In this issue of the “Special Report on Construction Costs per Square Meter,” we will introduce the construction costs of detached residences in Japan in 2020 by focusing on the unit price per square meter.
In general, the construction cost of detached residences varies depending on the structure of the building and the region, so we will look at construction cost levels by prefecture as well as recent trends from the viewpoint of structures as follows.Construction costs of detached residences by structure

- Construction costs of detached wooden residences (as condominiums)
- Construction costs of detached steel residences (prefabricated construction method)
- Construction costs for detached reinforced concrete residences
