Abstract
The purpose of this paper is to investigate the future renewal-policy orientations of suburban detached-house estates developed in a high-growth period, by conducting field surveys on Hitachi-city-the company city of Hitachi, Ltd. We examined suburban detached-house estates concerning the formation process, the actual conditions and evaluation of living environment by residents. Our results clarified the following points: 1) the local government and the affiliated firms of Hitachi, Ltd. had played importan roles in supplying lots of suburban detached-house stocks. 2) the majority of residents want to continue living at the current properties, but the sustainability of everyday life of elderly people in the suburban detached-house estates is seriously concerned because of the problems accompanied with aging, slopes in the estates and decrease in the level of convenience in daily life or shopping. 3) it is expected that lots of vacant lots and vacant houses will appear in the inconvenient estates located in the hillsides.
