By the end of the 1960s, large-scale architectural projects were discredited in West because they were associated with the established Power. Influenced by the ideals of May 1968, architects began searching alternative models based on the Historical language. They wanted to reach the autonomy of the architectural form by releasing it from their supposed ideological content, which was adhered to the abstract modern forms. Nevertheless, the post-modern approach, which was based on formal elements of the architectonical object and of the urban space, implied in the relinquishment of the metropolitan-scale. This urban-scale would be characterized by the references loss of organic formal structures. In Japan, modern research on large-scales was not interrupted, offering an important arsenal to the questions of contemporary urbanism. This dissertation verifies how the architects Fumihiko Maki and Rem Koolhaas propose the retaking and revision of modern metropolitan urbanism. They presuppose that architectonical Form is devoid of intrinsic meaning. Its appropriation by Power and also by people gives it meaning, removing architects responsibility on the totality of the project and giving them back the legitimacy of the discipline. This research follows the paths opened by these two architects through their Eastern and Western references, revealing the many instances in which architectonical concepts of both worlds converge, aiming to the persistence of modern thought.
