The dreams of the collective housing of the modern movement probably mark the origin of a housing genealogy that this study follows through the comparative analysis of 100 projects carried out in Mexico from the beginning of the 20th century to the present. Among them, we find works by architects as well known as Juan O’Gorman, Luis Barragán, Mario Pani, Hannes Meyer, Alejandro Aravena or Alberto Kalach. Based on vintage photographs and redrawed drawings, Collective housing in Mexico not only examines the basic parameters of each of the works studied, but also points out some of the fundamental issues that have accompanied the debates on the collective housing formula, as the problems of residential segregation, the idea of a productive house or the role of current policies. A deep and complete study that provides new keys for the construction of a habitat culture that explores the relationship that exists between what belongs to one and what belongs to everyone.
