The building has fourteen above-ground stories and five basement levels. Because the design was intended to accommodate up to 4,000 employees, the placement of elevators and entrances was a main consideration. Since Nassau Street was such a busy street, and because the slope was so steep, the architects decided to place the main entrance at Liberty Street instead, with the service entrance along the raised basement at Maiden Lane. The facade and interior contain ironwork manufactured by Samuel Yellin of Philadelphia. The iron decorations, which weigh a collective , depict animal heads and unusual motifs such as smileys.
