Abstract
Plans for public housing should be modified to meet varied needs of its occupier but needs are not static as family circumstances are constantly changing. New plans to be proposed should satispy not only varied needs but also changes of needs. We started the research to make its variety and change clear. Conclusions are as follows; (1) The conventional plan, so called "3 DK", does not provides adequate space for varied family life. A lot of people rearrange the living area to suit their needs. (2) The way of life changes radically over 3〜5 year period when the first baby enters school. During that period husband and wife often sleep separately. It seems to be the result of small main bed room. (3) Majority of residents move furnitures, especially clothes cabinet, to meet changes of circumstances. Furnitures thus moved are often put with no regard to the use of the room. This is due to the improper arrangement of rooms. By the above couclusions we propose adaptable living units with flexible walls. Its details are to be studied as our next subject.
