This 900-foot aluminum and glass skyscraper is the fourth tallest
building in New York and the tenth tallest in the world. The entire
structure rests on a central core and four outriding column-like towers.
A computer driven load mass damper enables the reduced number of
vertical supports and ensures the stability of this complex
structure. Double-decker elevator cars reduce the area devoted to the
vertical circulation core, leaving more space available for offices.
With so few interior columns, ample room is available for numerous
as a six-story retail wing and a sunken plaza that leads directly to the
subway. Plans for creating residential space on the upper floors were
abandoned due to zoning restrictions. Regardless, as a mixed-use complex,
this building has more in common with Art Deco skyscrapers than with the
purely corporate structures of the International Style.
The obliquely slanting roof--originally designed to hold solar
panels--embodies another break with the practices of corporate high
modernism. Standing out among the flat-roofed prisms of midtown,
Citicorp's pitched roof has become a symbol of the corporation, a marker
of corporate identity in an emerging area. The building's
bold presence helped to revitalize the commercial area located to the
east of Park Avenue.
