The Hearst Tower is a building at the southwest corner of 57th Street and Eighth Avenue, near Columbus Circle, in the Midtown Manhattan neighborhood of New York City. It is the world headquarters of media conglomerate Hearst Communications, housing many of its publications and communications companies. The Hearst Tower consists of two sections, with a total height of and 46 stories. The six lowest stories form the Hearst Magazine Building (also known as the International Magazine Building), designed by Joseph Urban and George B. Post & Sons, which was completed in 1928. Above it is the Hearst Tower addition, which was completed in 2006 and designed by Norman Foster. The building's main entrance is on Eighth Avenue. The original structure is clad with stone and contains six pylons with sculptural groups. The tower proper contains a glass and metal facade arranged in a diagrid, which doubles as its structural system. The original office space in the Hearst Magazine Building was replaced with an atrium during the Hearst Tower's construction. The tower is certified as a green building as part of the Leadership in Energy and Environmental Design (LEED) program. The Hearst Magazine Building's developer, William Randolph Hearst, had acquired the site for a theater, in the belief that the area would become the city's next large entertainment district, but subsequently changed his plans to allow a magazine headquarters there. The original building was developed as the base for a larger tower that was postponed due to the Great Depression. A subsequent expansion proposal during the 1940s also failed. The New York City Landmarks Preservation Commission designated the facade of the original building as a city landmark in 1988. Hearst Communications, having considered expanding the structure again in the 1980s, finally developed its tower during the first decade of the 21st century.
