The colonnade contains a pair of columns at each end, as well as two single columns in the center. Within the colonnade's bays, there were three sculptural groups supported on pedestals. The sculptural groups were each tall and depicted DeWitt Clinton (carved by Daniel Chester French) and John Jay and Alexander Hamilton (carved by Philip Martiny). Near the top of the colonnade are oval windows overlooking what was originally the Chamber of Commerce's main room. These windows are supported by brackets, with a frieze of wreaths below each window, as well as swags above. Above the colonnade is an entablature with modillions and dentils beneath it. The leftmost bay on Liberty Street is not included in the colonnade but has an oval window above a large rectangular window. The Liberty Place facade contains similar oval windows at the top of the wall, although they are subdivided by flat pilasters. The third and fourth floors were originally set back behind the Liberty Street facade, creating a terrace above the colonnade. The third floor is plainly decorated, with paired windows in each bay, while the fourth floor is within the dormer roof. Within the mansard roof, there are three dormer windows each facing Liberty Street and Liberty Place. The dormer windows are topped by decorative hoods and flanked by volutes on the side.

The building's elevators, as well as a stair to the second-floor Great Hall, were placed at the end of this hall. The design of the stair was inspired by the Ducal Palace in Venice and led to the second-story main room and elevator hall. The decoration of the hall's upper half was extremely elaborate. Colored-marble Ionic columns supported a frieze, above which rose a domed ceiling. Between each set of columns, there were tablets that were inscribed with the names of the Chamber of Commerce's officers. At the time of the building's construction, the tablets accommodated names of past officers and could be inscribed with the names of future officers. The rest of the ground floor was rented out as a banking room, the only commercial concern in the building. In general, the upper stories had decorative woodwork and marble work. On the third and
