The article examines how the concept of the addressee of architecture has been transformed throughout the twentieth century, demonstrating how the mutations of the dominant means of representation in architecture are linked to the evolving significance of the city’s inhabitants. It presents the ways in which the reorientations regarding the dominant modes of representation depend on the transformations of architects’ conceptions of the notion of citizenship. Through the diagnosis of the epistemological debates corresponding to four successive generations – the modernists starting from the 1920s, the post- war era focusing on neorealist architecture and Team 10, the paradigm of autonomy and the reduction of architecture to its syntactics and to its visuality in the 1970s and the reinvention of the notion of the user and the architectural program through the event in the post-autonomy era – it identifies and analyses the mutations concerning the modes of representation that are at the heart of architectural practice and education in each generation under consideration. It traces the shifts from Le Corbusier and Mies van der Rohe’s fascination with perspective to the Smithsons’ Cluster City diagrams and Shadrach Woods’s ‘stem’ and ‘web,’ on to Peter Eisenman’s search for logical structures in architectural components’ formal relationships and his attraction to axonometric representation, and finally to Bernard Tschumi and OMA’s concern with uncovering the potentialities hidden in the architectural program.
