The GE Building is a seventy story steel frame limestone-clad skyscraper in the Art Deco style. The building base is clad in Deer Island granite, and the shaft is clad in Indiana limestone with aluminum spandrel panels. The main entrance is marked by Lee Lawrie's limestone and glass sculptural relief. It is roughly rectangular in plan with a maximum width of 190 feet. Its total area is about 2,200,000 square feet and height is 850 feet. It is the centerpiece of the entire Rockefeller Center, and it met demands for studio, retail and office space for the radio group, the original tenants. The building has distinctive setbacks derived from the principle of providing light and air to all parts of the building. The building represented the ideal modern skyscraper in its own metropolis, Rockefeller Center. The influence of the center was great by providing open space to the public in a form of plaza, garden and promenade.
