Due to Korean government's reduction policy of the level of local administration, the government tries to become smaller and more efficient organization and in accordance with this movement, they try to transfer the human power and work of the office of Eup, Myeon, Dong to the office of Si, Goon, Goo so that they can take administrative action quickly, increase the efficiency of administration by preventing the overlapping of administrative task, improve the administrative service toward the citizens and make a functional shift of Inhabitant Self-Government Center in a way that is aimed at improving the quality of life of the inhabitants by setting up cultural, welfare facilities and forming the local community. Hereupon I expect this study will help to show the ways of composing the space of community center, accommodating the various demands of inhabitants through appropriate area calculation of functional area, increasing the efficiency of government officers' administrative support and also will be the guide for the architectural designs of the community centers. For this purpose, I have investigated community centers of 8 Dongs out of 11 Dongs in Goon-po Si that was chosen to be operating the pilot program of the office of Eup, Myeon, Dong's functional shift and obtained excellent results. I have surveyed how the functional spaces are being used, interviewed the government officials, examined the size of the functional and required space with Building card of a plan and the analyzed results are as follows.
