Architecture The Chamber of Commerce Building was designed in the Beaux-Arts style by architect James Barnes Baker, a member of the Chamber of Commerce of the State of New York, for which the structure was erected. The building was expanded in 1922 by Helmle & Corbett, while the interior design dates to a 1991 renovation by Haines Lundberg Waehler. Charles T. Wills served as the primary contractor for the original work as well as for the 1922 expansion. The building is four stories high, plus a half-story attic.

Facade The facade is made of Vermont marble upon a base of rusticated blocks of masonry. The top story is housed in a mansard roof clad with copper. The main facade on Liberty Street contains four vertical bays and is divided horizontally into three sections: ground story, second story, and third and fourth stories. On Liberty Street, the leftmost bay is generally more elaborate than the three rightmost bays. The side facade on Liberty Place is similar to that on Liberty Street, though more simple in design, and is five bays wide. There are two entrances at the ground story on Liberty Street, both raised slightly above street level. The entrance to the building's ground floor is within a segmental arch in the second bay from the right; it is flanked by two full-height windows, one on each side. A more ornate entrance to the upper levels protrudes slightly from the leftmost bay. The left entrance is topped by an arched pediment with an elaborate carving. Above that entrance was a carving by Karl Bitter, which contained depictions of Ceres and Mercury, two ancient Roman gods that collectively depicted commerce. A carved marble band runs above the ground story. On the second floor, in the three rightmost bays facing Liberty Street, there is a small colonnade with six double-height fluted columns topped by Ionic-style capitals.
