The IAC Building, InterActiveCorp‘s headquarters located at 550 West 18th Street on the northeast corner of Eleventh Avenue in the Chelsea neighborhood of Manhattan, New York City, is a Frank Gehry-designed building that was completed in 2007.
Reminiscent of several other Gehry designs, the building appears to consist of two major levels: a large base of twisted tower-sections packed together like the cells of a beehive, with a second bundle of lesser diameter sitting on top of the first. The cell units have the appearance of sails skinned over the skeleton of the building. The full-height windows fade from clear to white on the top and bottom edges of each story. The overall impression is of two very tall stories, which belies its actual 10-story structure. Vanity Fair commented that the building is perhaps one of the world’s most attractive office buildings. Barry Diller, the head of IAC, mandated that the facade be covered in smooth glass rather than wrinkling titanium, as Gehry had originally planned.
