狭小宅地住宅地区における住宅建て替えポテンシャルの低下傾向について

Abstract

In this study, we resarched the changing situation of the housing and environment on the small-site houses areas. The small site houses area is defined that more than a half numbers of all houses in the range of there are small site houses, whose site area is less than 100 square meters per unit. These areas mostly have been developed during from 1920 to 1945, while heavy industrial factories have been located on Nagoya city. And many workers and their families have come to live in small site houses on these areas. But in this study, we found that in these areas, housing rebuilding potential of the living peoples have been declining since near upon 1980. We concluded that these affairs caused by following reasons, (1) The factories around there scattered and relocated to suburban areas, and workers who laboured in these factories moved out to suburban areas, too. (2) Many peoples living in small site areas have aged, and their sons and daughters have left their home, and will not come back to live there. (3) Aged families, the number of them are increasing day by day, have not so much income or saves that they cannot but giving up to improve their houses. (4) The each site areas are so small that any landlords and privite enterprises would not have intentions to implement redevelopment action on these areas. This study came to conclusion that they are useful for renewal of these areas, such planning methods as to repair old houses for aged families and to supply new houses for return of young families.
