The campus concept, that both echoes the bases of antic cities and more recent american models, enables to build up an explicit urban and land development project, made of open flows, multiple connections, free and easy appropriation of the public space. The question that arouses is about land thematization, what it is oriented for, its public image, its representations and its programming. At the very core of this definition is the link between free space and specific places, in a purely urban context as in a service-oriented, academic, hospital or economical-oriented context. Before urbanization, volumes and composition definition, come a specific study of the site, the geography and the programming.
