The reuse of abandoned lots within Querétaro’s Historic Center is the starting point of an urban strategy aimed at reversing the area’s physical and social deterioration. re-itera proposes an affordable, flexible, and site-specific collective housing typology, capable of adapting to the unique conditions of each lot and the transformations of the inhabited environment. The project introduces a replicable, adaptable housing module that responds to the site’s physical, historical, and regulatory constraints while enhancing the built environment.
