The intervention responds to the architectural attributes of the Cabañas Cultural Institute. The building is developed on a single architectural floor perforated by 23 courtyards. Once inside the building, the only connection with the outside is through its patios that reveal the sky. The sculpture is a 1:20 scale model in negative. In other words, the 23 courtyards of the building are the ones with volume and which, as they are covered by mirrors, reflect the sky.
