The increasing apartment houses in the Hanshin-Awaji disaster areas exposed the problems in existing residential areas. We selected 4 distinctive districts to implement interview research, field investigations and analyses of materials or maps. First, we illustrated, through regulations and the processes of changing urban areas, the actual conditions of the periods when apartment houses are being built. We clarified the basic points on architectural planning in apartment houses as a next step. As a result, we demonstrated the realities of apartments after the earthquake, the problems on transient remedies and the differences according to site scales, provision systems.
