[4][5] In 1956, as an Italian member of the Congrès Internationaux d'Architecture Moderne (CIAM), De Carlo presented his own project for a housing complex in Matera in which all the principles of le Corbusier are ignored at the expense of specific attention to the geographical, social and climatic context of the region.
In 1956, the current CIAM congress concluded and Team 10 began, bringing together a new generation of architects (including De Carlo, Alison and Peter Smithson, Aldo van Eyck, and Jacob "Jaap" Bakema) to conceive a new type of architecture, one which was better suited to local social and environmental conditions and where the man "is not reduced to an abstract figure".
In 1978, he founded and directed the magazine Space and Society to maintain the Team 10 network and guarantee an alternative and independent voice in the European architectural sphere for the next 20 years.
