東京区部における住宅地区改良事業候補地区の変容実態について

抄録

A survey on the poor housing districts in Tokyo-ku-area was conducted six times between 1957 and 1975. It was found as a result that 464 districts need to be improved. Only 80 out of these, however, were improved by "slum clearance project". The purpose of this paper is to show how these 464 districts have changed so far on the basis of surveys on actual condition. The improvements of districts fall into the following six types : 1) The district that (was cleared and) turned into school districts or local parks, e.g. 2) The district that (was cleared and) turned into public housing complexes 3) The district that (was cleared and) turned into commercial districts for supermarkets, e.g. 4) The district where individual houses were rebuilt by their owners 5) The district where individual houses were repaired by their owners 6) The district where no improvement was done and that remained substandard : The percentage of these six types are 6.9, 19.8, 2. 6, 62.5, 7.5, 0.6, respectively. It can be said, therefore, that most of the districts were improved through rebuilding and repairing of indivdual houses. Althogh these houses were improved housing environments (environment around houses) started to have problems such as overcrowded dwelling, shortage of roads and parks. In short, poor housing distrcts turned into the poor housing environment area (the environment around poor houses).
