Lever House is an office building at 390 Park Avenue in Midtown Manhattan, New York City, that was originally the US headquarters of the soap company Lever Brothers, a subsidiary of Unilever. Constructed from 1950 to 1952, the building is 307 feet (94 m) tall and has 21 office stories topped by a triple-height mechanical section. It was designed by Gordon Bunshaft and Natalie de Blois of Skidmore, Owings & Merrill in the 20th-century modern International Style. Lever House was the second skyscraper in New York City with a glass curtain wall, after the United Nations Secretariat Building. The skyscraper was nearly demolished in the 1980s before being designated as a city landmark. After the construction of Lever House, many masonry residential structures on Park Avenue in Midtown were replaced with largely commercial International Style office buildings. Its design was also copied worldwide by buildings such as the Emek Business Center in Ankara, Turkey. (Full article...)
