The Classical Revival style building is distinguished by Art Deco architectural elements, and its innovative use of aluminum for details that were traditionally cast in bronze. All entrances to the building feature 20-foot-high aluminum doors that slide into recessed pockets. Interior stair railings, grilles, and door trims are aluminum, as are Art Deco torchères, doors for the building's 25 elevators, and more than 10,000 light fixtures.
