The purpose of this paper is to make clear the transformation process for 20 years of the co-operative housing "U-court".
In management action, it is based on voluntary management for 20 years. And the organization and method are transfigured so that it may correspond to the necessity for community life. In the action for enjoyment, the adult resident took action as enjoyment of oneself first, and it was activated by children being involved in there.
The sense of values formed of living together has produced the next activity. The chain for which activity induces the next activity is a factor which the power of living together maintains. The resident's aging will advance further in the future. It will be asked how the power of living together works.
