The idea that a school could take a role of educating each community personnel as well as students and the school building could be a center in a community is discussed in this paper. Also, as rental housings being included in the community and placed near school buildings, school facilities can be shared and cover the shortage of social welfare facilities. Thus urban social facilities including schools, social and cultural facilities, and rental housings should be planned as a bundled scheme. The objective of this Paper is to find the suitability of building a complex of school, gymnasium, cultural facilities, welfare facilities in school sites, and building rental housing in public building sites, such as cultural facilities and welfare facilities, gymnasium sites in the City of Pyeong Teak. It is found that this assumption can be proved when building a public school of 6 to 7 story or a rental apartment with a floor area ratio of 150% - 200%.
