Unasur is an institutional headquarters building located next to the Mitad del Mundo monument, north of Quito, Ecuador. About 75 percent of the program is placed underground, so the volume stays lower than the nearby monument. A solid reinforced concrete core supports two large metal trusses that form a habitable beam with a cantilever of 56 meters without support. Materials include concrete, steel, rock from an on-site quarry and double glazed dark glass. Water collection, cross ventilation and natural light reduce energy use. Open areas around the building are public.
