This handbook presents five housing prototypes that were built by low income families from the Ejido Ocuilapa de Juárez, with training and technical supervision of members and collaborators of the University Faculty Urban Development (CADU) and students from the School of Architecture at UNACH. In the prototypes design, the typological and environmental characteristics of the place, uses and customs, health and safety were considered, along with technical aspects that were necessary to have low cost and safe households.
