Piano Progetto Citta is an instrument for dialogue between Architecture and Urban Planning. Promoted by the Dipartimento Ambiente Reti Territorio (DART) and the Dipartimento Infrastrutture Design Engineering Architettura (IDEA) has, over the course of the years, developed a notion of design as a transversal and inter-scalar dynamic. During this period, PPC has confronted issues raised by international debate (urban design, the landscape, infrastructures, environmental compatibility, the role of context in the process of design, the interweaving between the local and global, etc.).
