The dreams of collective housing promoted by the Modern Movement give rise to a housing genealogy that this study traces through the comparative analysis of 125 projects built in Mexico from the early twentieth century to the present, including works by architects such as Juan O’Gorman, Luis Barragán, Mario Pani, Hannes Meyer, Alberto Kalach, and Frida Escobedo. Through historical photographs and redrawn plans, this second revised and expanded edition of Vivienda colectiva en México examines the essential parameters of each project and addresses key issues such as residential segregation, the notion of the productive house, and the role of contemporary policies, offering new insights into the relationship between the individual and the collective in the construction of the built habitat.
