The spatial and architectural project was built on a dynamic vision of Cachan campus, whose progressive transformation is inherited from the site’s potentialities. Thus, the campus’s open landscape, its extensive vegetation, the ground-plan, and Roger-Henri Expert’s architectures, shape the new project’s structuring fundamentals. The project emphasizes the constitution of high quality exterior spaces, which will support both soft mobility and the campus’s various purposes. To the west, the entrance court has been remodelled and becomes a symbolic space as much as an interface with the town, activated by the renovated gatehouse The Porterie, which serves as a unifying third space.To the east, an ensemble of housing units is installed on the south part of the plot, freeing up an open, a large grassed clearing, a new living space of the campus, and a square that functions in conjunction with the new shops at the eastern entrance. The new buildings suggest many ways of inhabiting the campus.
