The management of the state in the approaches of repeated housing models in Bogota in the middle of the twentieth century was definitive for the modernization and transformation of large sectors of the city. Although it never managed to approach the requested demand, the proposals developed initially by the Department of Urbanism and then by the public agents that were dedicated to financing and housing management such as Caja de Vivienda Popular, Instituto de Credito Territorial and Banco Central Hipotecario, marked a precedent in terms of urban, architectural, technical and social experimentation, in collaborative work with the leading studios of architects of the moment. Between 1938 and 1958, this public agents designed and built paradigmatic neighborhoods as Centenario (1938), Popular Modelo Norte (1942), Los Alcazares (1949), Muzu (1949), Quinta Mutis (1955) and Polo Club (1958), that give an evolutionary account of this process of transformation, marked by hygienist concern, urban exploration, constructive efficiency and social assistance.
