The tower's facade is made up of vertical piers of limestone and horizontal spandrels of matte buff brick. The piers protrude outward from the rest of the facade. The facade of the core of the tower, which contains the elevators, stairwells, and utilities, is made of glazed black brick. The tower's windows are grouped in sets of four on the east and west sides of the tower. The north-side windows stretch across its entire length except for at the fourth and fifth floors where the windows are two sets of four flanking a set of six. The 21st floor, a mechanical floor that houses the air conditioning equipment, has narrower windows than on the rest of the building.
