Kavanagh Building
The Kavanagh Building () is a residential skyscraper in Retiro, Buenos Aires, Argentina. Designed in 1934 by architects Gregorio Sánchez, Ernesto Lagos and Luis María de la Torre, it is considered a pinnacle of modernist architecture. At the time of its inauguration in 1936, the Kavanagh was the tallest building in Latin America surpassing the Palacio Salvo built in Montevideo, Uruguay in 1928, as well as the tallest building in the world with a reinforced concrete structure. It is considered one of the quintessential buildings of Buenos Aires. A 2013 Clarín survey of 600 people who are not architects or builders found that the Kavanagh is the building most liked by porteños. The Kavanagh Building was declared a Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1994 and a National Historic Monument of Argentina in 1999. Location The Kavanagh Building is located at 1065 Florida Street in the barrio of Retiro, overlooking Plaza San Martín. History It was designed in 1934, by local architects Gregorio Sánchez, Ernesto Lagos and Luis María de la Torre, built by the constructor and engineer Rodolfo Cervini, and inaugurated in 1936. Standing at a height of 120 meters, the building is characterised by the austerity of its lines, the lack of external ornamentation, and its large prismatic volumes. It was declared a Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1994 and a National Historic Monument by the Argentine government in 1999. In the year of its completion the building obtained the Municipal Award for Collective Houses and Facades (), and three years later its façade received a similar award from the American Institute of Architects. It was commissioned in 1934 by Corina Kavanagh, a millionaire of Irish descent who sold two ranches at the age of 39 to erect her own skyscraper. Construction took 14 months. The building has a towering form, with symmetrical setbacks and gradual surface reductions. It was created from the outside in. The structure was designed to be as slender as possible, in order to avoid unnecessary weight, and influenced by city planning regulations. The design combines Modernism and Art Deco with a Rationalist approach, and is considered the apex of early Modernism in Argentina. The building of the concrete structure was awarded to the Empresa Argentina de Cemento Armado, E.A.C.A. of engineers Garbarini, Meuer and Gorostiaga. The tender was made based on a preliminary project prepared by structural engineer Carlos Laucher. The final design of the structure was executed by the Technical Office of E.A.C.A., led by Eng. Fernando Schwarz, responsible for the design and calculations of the highest concrete skeleton in the world. At the time soil mechanics—used to calculate the bearing capacity of the ground—was in its infancy, and there were limited tools to calculate wind resistance. It was at the time the highest skyscraper in Latin America. As the apartments in the new building were aimed at the affluent upper middle classes, no expense was spared in its
