Most of suburban housing estates developed over 25 years ago, that is in Showa period, have changed by rebuilding and repairing, especially from the viewpoint of outer walls of those houses. And the scenery of the estates has been changed to some extent. In this paper, we have investigated three suburban estates in order to analyze and compare how outer walls of those changed through years and also what the present conditions are. We actually looked at the outer walls of all houses and did a questionnaire survey to the people living in those areas.
