SURVEY OF THE REBUILT DETACHED HOUSES IN HOKKAIDO

Abstract

We obtained information by means of questionnaires on the rebuilt houses and their pre-rebuilt ones. The following are the results. 1.Concerning about their construction methods, approximately 84% of the pre-rebuilt houses used Japanese conventional methods, but only 55% of the newly built houses used such conventional methods, instead the rest of them used wooden panel system, platform wood frame, and light-weight steel construction method. 2. It is thought that old houses built by new construction method have various problems, but those problems of new houses have been vastly improved. 3. Pre-rebuilt, old houses were built by a large number of construction companies nearby, but the number of big companies such as so-called "house-makers" has increased. However, around 40 percent of new houses are built by construction companies nearby.
