Lever House

Lever House is a glass-box skyscraper at 390 Park Avenue in Midtown Manhattan, New York City. Built in the International Style according to the design principles of Ludwig Mies van der Rohe, the building was designed by Gordon Bunshaft and Natalie de Blois of Skidmore, Owings and Merrill. Completed in 1952, it was the second curtain wall skyscraper in New York City after the United Nations Secretariat Building. The 307-foot-tall building features a courtyard and public space.

The construction of Lever House marked a transition point for Park Avenue in Midtown, changing it from a boulevard of masonry apartment buildings to one of glass towers as other corporations adopted the International Style for new headquarters. The building's design was copied by Ankara's Emek Business Center in 1959; the Minneapolis bank headquarters One Financial Plaza in 1960; Paris Orly Airport's Terminal Sud in 1961; and the high-rise tower of Berlin's Europa-Center in 1965.
