The school complex project is driven by public calling for school facilities change due to the social change followed by the aging society and increasing interest in the lifelong education. The school complex project is defined as an activity in which the school facilities and space are not only used for students, but also for the local residents. Since the project was promoted in a link with reform of the education system in 2001, the demand in the expectation effect has been sharply increasing. Despite of the high expectation and attention, the school complex project, however, has been performed in a limit of efficiency. Consequently, public opinion calling for more structured and effective way on construction and administration has been certainly increasing. According to the strong demand, this study was carried out to provide basic data for, and suggest an approach to, more structured and effective way of establishment and administration of the school complex project by comparing the success cases in Seoul metropolitan city.
