Climat de France, a modernist housing complex in Algiers, was built in the 1950s during the final years of French colonization. Over the years, its residents have modified the original design
by the French architect Fernand Pouillon, based on use, lifestyles, and local resources. Utilizing
archival and photographic documentation, videos, and interviews to identify, characterize, and
classify the modifications on the outer façades, this paper infers visual rules as generative and
formal tools to analyze the continuity and discontinuity between socio-cultural acts and idealized
forms in mass-customized housing.
