The present study is performed to clarify the structure, explanatory elements, trends and references of campus master plans. The campus master plans studied were from 42 universities in the U.S., Canada and Australia. The results were as follows; 1) Campus master plans consist of an introduction, discussion of the existing setting, targets/policies, plans and application, and can be classified into expansion, element-oriented and task-oriented types. 2) Master plan components can be classified into ten categories: existing setting, land use, space, access, campus image, infrastructure, community relations, facilities, environment and other. It is campus image and access that there is much appearance in Campus master plans.
