As part of a redensification program to transform areas of increasing abandonment, a social housing building of four levels will be implemented near the city limits of Durango, Mexico. The building provides fours apartments of varying sizes for occupants of low income in addition to spaces for small businesses on the ground floor that contribute to activating the street life. A central patio allows for natural ventilation of the inner rooms and connects all floors up to the communal roof terrace. Round corners are introduced to all edges of the volume in reference to the traditional round corner motif of historical buildings in downtown Durango. The name ‘Torre Roja’ i.e. ‘Red Tower’ is borrowed from the colour of its construction material, red bricks.
