The villa is located in an elevated area with a strong slope in the city of Leiria, Portu-gal. The conditions of the subdivision suggested a volumetry of a tower, a viewpoint over the city. One of our premises was that the social areas were located on the upper floors and the swimming pool on the roof, to enjoy the 360º view. The structure and the concrete skin are a single body, rhythmic with 18 horizontal rings, which design the house in a game of full and empty, creating a protective filter, both solar and privacy.
