Constructed in the Neoclassical style, the building has a basement, three storeys and a penthouse.[1] It incorporates an older residence that faced the Plaza de Mayo but now fronts the Avenida Julio A. Roca. The main door, located at the corner of Avenida Julio A. Roca and the Calle Peru, is of carved wood with a central brass knocker shaped as a lion's head. The front of the building has Corinthian style colonnades and balconies with balustrades.
