Lever House is a 307-foot-tall (94 m) office building at 390 Park Avenue in the Midtown Manhattan neighborhood of Manhattan in New York City, United States. Constructed from 1950 to 1952, the building was designed by Gordon Bunshaft and Natalie de Blois of Skidmore, Owings & Merrill (SOM) in the International Style, a 20th-century modern architectural style. It was originally the headquarters of soap company Lever Brothers, a subsidiary of Unilever. Lever House was the second high-rise in New York City with a glass curtain wall, after the United Nations Secretariat Building.
