The purpose of this paper is to make clear the relation between evaluations of living conditions in renewed public housing and prior expectations for the renewal program, based on a questionnaire submitted to residents of H.U.D.C. housing estates. The results are as follows; 1) Residents evaluated dwelling units as private space much better than public exterior space. 2) Although residents are not satisfied with the individual factors of the public space, they approve of the present layout of residential buildings as a whole. 3) They would have wished to participate in the renewal program to some extent. However, light participation does not generally produce significantly different results.
