Throughout the 1920s and 1930s, Le Corbusier advanced a vision of architecture that linked the “cell” of the domestic unit to the scape of a new city. On the one hand, he was committed to finding new forms of architectural expression – his influential “Five Points towards a New Architecture” (1926) sought to establish rules that, as he put it, “in no way relate to architectural fantasies or a striving for fashionable effects, but concern architectural facts that imply an entirely new kind of building, from the dwelling house to palatial effects.” What, exactly, were these “rules” or “facts”? How did Le Crobusier use the “Five Points” to create new forms of the domestic environment, whether in the private home or in the apartment block? To what degree were the “Five Points” dependent on his important earlier Maison Dom-ino prototype? On the other hand, Le Corbusier was instrumental to defining new – and influential – goals and techniques of city planning that crystallised in the formation of Congres intemationaux d’architecture modeme (CIAM) in 1928. As the architectural historian Kenneth Frampton argues, “Unlike his European contemporaries… Le Corbusier was anxious to develop the urban connotations of his architecture.” How, exactly, did Le Corbusier do this? For example, what kinds of links may be seen between his ideas on housing and unrealised urban plans such as the Plan Voisin and Ville Radieuse? How were the “Five Points” used in both architecture and urbanism? In the absence of realising his prewar urban designs, how did Le Corbusier distill his key ideas – architectural and social – in the Unite d’Habitation of 1952? Frampton notes a change in Le Corbusier’s sense of class relations from the Contemporary City to the Ville Radiuese. Thus, what kinds of social ideals did he project – through specific forms, programmes, or techniques of building – in both his architecture and urbanism? How did these approaches shape the Unite d’Habitation in terms of Le Corbusier’s fascination with nineteenthcentury utopian socialists such as Charles Fourier (or in the formative experience of the Charterhouse of Ema – a monastery – which deeply marked his conception of housing)?
