Comega Building, Rationalist skyscraper on Avenida Corrientes, Buenos Aires, Argentina
The Comega Building is a skyscraper on Avenida Corrientes in downtown Buenos Aires, rising 22 floors with an exterior clad in travertine stone. It follows a rationalist style, with clean geometric lines and no ornamental decoration on its facade.
Built between 1931 and 1934 for the Compañía Mercantil y Ganadera S.A. (COMEGA), the Comega Building rose on the site of Francisco Madero's former residence, later the Gran Hotel Nacional. It was the first reinforced concrete skyscraper in Argentina and the first in Buenos Aires with an exterior fully clad in travertine. In 1936 the Kavanagh Building surpassed it in height.
The Comega Building stands on Avenida Corrientes, a street known for its bookshops, theaters, and cafés that stay open late into the night. The stone facade catches the eye among the surrounding buildings, making it a natural reference point for people walking the avenue.
The Comega Building stands at the corner of Avenida Corrientes and Avenida Leandro N. Alem, near the Stock Exchange and the Casa Rosada. Its two wings and taller central tower frame an open courtyard facing Alem. The building has two underground garage levels, and the interior, with granite cladding and stainless steel counters, is largely reserved for office tenants.
The 19th floor once housed the Comega Club, a private gathering space where members watched major events over the city, including the arrival of the Graf Zeppelin, until 1969. Having a private social club inside a skyscraper was unusual for Buenos Aires at the time.
