Abstract
Many people are currently living in residential area. It has been intended to form a safe and quiet environment where
people can raise their children with security when residential area is specifically dedicated to a residential function by
separating a place into residential area and working area. However, safety awareness sometimes may create excessive
consciousness of privacy and eventually lead to individualized residential area and diluted mutual relation.
Since the concept of family and family style become more diverse such as population decline, aging and so on,
reconsideration is now required to examine the future of residential area. In such a situation, it would be effective to reexamine
residential area from a viewpoint of “Commons”.
We introduce the efforts at the local base type share house ”CASACO” which rebuilt the old townhouse, from the point of
view as designer-to-operation actor and also one of local residents.
