Abstract
This study aims to examine the role of a public entity for collective housing developments. The possibilities and assignments of five models of public collective housing were analyzed. The study shows possibilities of new models as a Silver-Housing with mutual support among residents and as a base to enhance regional community activities. These require education programs and continuing support to foster people who understand collective living. Also, the collaboration between a local government and non-profit professionals has a possibility to resolve various assignments of collective housing. To promote non-profit developments of collective housing, a local government will be expected to prepare outreaching programs and a subsidy for the construction.
