Antonio Solá is a residential building located in colonia Condesa, a neighborhood in Mexico City. It is in a rectangular plot of 9 x 27 m; the short face on the street side. The main façade has the best view and orientation. The four-story building contains one apartment per floor and the parking space at the basement. All the apartments are facing the street with sheltered balconies. The whole building opens itself to a narrow courtyard facing south giving the best orientation and cross ventilation. The idea of the courtyard is to encompass vegetation inside the building and provide the apartments a green view to eliminate clear boundaries. The courtyard also gives a sensation of being immerse in nature. The structure of the building is based on concrete walls with an apparent finish, and the interiors are made of neutral materials allowing the dwellers to appropriate the space.
