7 apartments, garage and 2 commercial units building. It is a building whose gestation, development, and licensing has been achieved after an arduous process of 10 years. It was the winning project of a private competition established by the promoting company. The design maximized the urban uses that had to be successively modified adapting to the changing criteria of the municipal ordinance, and to the special characteristics of the site that fronts two streets of different heights. A 2-volume composition joined by a central communication core was chosen. These volumes respond to the stereotomic idea, they are treated as units from which elements are subtracted, the gaps are materialized and both in vertical surfaces and on the roof they have the same ventilated finish of sintered stone pieces and together with their faceted geometry they form a unit . The base on which they are raised is made of exposed concrete, and has small perforations consistent with the nature of the material.
