780 Third Avenue NYC - 1983 - Skidmore, Owings & Merrill
570-foot, 49-story postmodern office building completed in 1983. Designed by Skidmore, Owings & Merrill, the building's exterior is patterned with polished red Balmoral granite panels from Finland alternating with grey-glass window openings in a diagonal pattern, covering the concrete panels which form the structural truss tube. The diagonal bracing can be seen on the building's facades in crisscross patterns created by omitting openings for windows. Unlike other X-type designs such as used on the exterior of the John Hancock Center in Chicago, also designed by S.O.M., the Third Avenue tower's bracing is within the walls. It rises as a sheer slab on all four sides in a slender rectangle form. The building is similar in design and height to Onterie Center in Chicago, completed in the same year.
