IAC Headquarters, New York, US

The building featured is located in the Chelsea neighbourhood of New York City. Completed in 2007 it houses the offices of IAC corporation. It appears at a gross level to consist of two major levels: A large base of twisted tower-sections packed together like the cells of a bee hive, 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 overall impression is of two very tall stories, which belies its actual 10-storey structure.

Vanity Fair, writing about IAC corporation, argued that this is perhaps the world's most attractive offices.

Architect : Frank O. Gehry
