Abstract:University campus boundary space is a zone between off-campus urban space and university campus, especially within the boundary of university campus land, which can be regenerated and reutilized. Under the context of innovation and refinement management of megacities, the regeneration of inventory space at campus boundaries should contribute a greater value. In addition to the various abstract attributes that “boundary space” has been recognised, based on the role of universities in cities and their relationship with urban regenerated practises, this paper proposes that campus boundary space should be regenerated and designed from the aspects of strengthening its three characteristics of domain, synergy and interest. Taking Wangjiang Campus of Sichuan University as an example, this paper studies the characteristics of campus regeneration dynamics and inventory space dominated by public buildings. By observing three different regeneration cases, this paper analyzes the reference of university campus boundary space regeneration from three aspects: field definition, university-locality coordination and interest superposition. The case shows that there are different ways of coordination between the campus, regenerating the boundary space, realising the multi-win situation of resource sharing and the coordinated development of multiple subjects.
