The commission was to build a 12-apartment building in the old city center of Seville on an irregular-shaped lot. The project concentrated the unconstructed space in a courtyard whose shape solved the geometrical problems the site posed, while also providing a focal point that drew attention from the many different lines of building hidden behind it. The courtyard provides the key to the organization of the entire building, marking off the areas to be occupied by housing and positioning the stairways. Vehicles gain access to the basement through the ground floor, which the inhabitants also pass through to reach the stairs to their homes.

The use of traditional Sevillian materials and construction techniques add significance to the final character of the building, making it relatively timeless and thus allow it to fit into the backdrop of the city center, so densely packed with history.
