A university campus with dense buildings like Ewa Womans University has several decision factors in terms of interaction with existing buildings. The important factors include various axes of geographical features and roads, interaction with exterior of building and the establish ment of new space due to a new building. Besides the difficulties of ground, each building has many unexpected variables in its functional, external, and social aspectes. We have conducted a couple of projects in the Ewha Womans Universary, but every project has its own difficulties.
