Since founding his workshop in Milan in 1950, De Carlo has been an active participant in the international architectural life. First he became a member of CIAM, continuing the tradition of modernism of the first half of the century, then entered Team X - the "team of ten" - along with Peter and Alison Smithsons, Aldo van Eyck, Louis Kahn and others. De Carlo gained fame thanks to his project of a campus near Urbino (1962 - 1966). In it, he expressed his theoretical views, according to which architecture should be consistent with the physical environment and social situation. The architect was engaged in the ensemble of the campus of Urbino University until 1983. The formal language of De Carlo's work, adjacent to brutalism, was fully manifested in the following decades in the projects of residential complexes, such as the Matteotti working village in Terni (1970-1975) and the ensemble of "social housing" in Venice - Matterbo (1979-1986).
