Constructing freestone buildings on the cheap, Pouillon made a name for himself at the end of the 1940s in Aix-en-Provence and Marseille, shaking up his peers who only dreamed of towers and concrete bars. In Algiers, until Independence, he built in record time thousands of homes for the poorest, real urban projects inspired by traditional forms. In the Paris region, to build comfortable buildings quickly and well, nestled in the greenery, he becomes a promoter: this too adventurous bet leads him to prison and retains his reputation. Not very explicit about this complex affair, but seduced by a contemporary architecture that combines technical inventiveness and ancient references, Christian Meunier films by multiplying the angles of view. Today's lively atmospheres are interspersed with archive footage, while Pouillon's writings are read off. Moved, his collaborators evoke a demanding and generous man, with an infectious passion.

In this documentary, Marie-Claire Rubinstein reveals to us, through the testimonies of the inhabitants who live there, the architectural achievements of the French urban planner Fernand Pouillon in Algiers. In particular the vast complexes of hundreds of social housing units, including the most famous Diar E Saâd (1953), Diar El Mahçoul (1954) and Climat de France (1957). The historical context, during the war of independence is related by the historian Benjamin Stora and Nadir Boumaza. This documentary also evokes the personality of Fernand Pouillon in a post-colonial context.
