Abstract
This report is part of a series of studies (preceded by Part 1 and Part 2) targeting the residents of a cooperative housing complex that includes threegenerational residences. The study goes beyond conventional concepts for facility planning involving the providing of needed functions, by clarifying the need for living space planning with a mutual permeation of consciousness with regard to people, activities and spaces, in order to form an allencompassing creativity for group living and leisure time. The management and leisure activities of those who live in cooperative housing complexes that include three-generation residences produce a mutual permeation of consciousness in terms of both concrete achievements and attitudes. This study is pursued from the standpoint of ways to conduct process planning in order to provide a unique personality to the quality of space.
