& van Vleck's commissions were in the neoclassical style, while the addition was designed when Art Deco style was popular. The trading floor was trimmed in a Renaissance Revival style, but the main structure is distinctly Art Deco, a product of the 1929-31 addition. The Trinity Place annex may have been influenced by designs from the firm's younger employees, including Frank Gaertner, who had submitted the annex plans to the New York City Department of Buildings. The annex's style is similar to that of the Downtown Athletic Club and 21 West Street, located several blocks south, which were designed by Starrett & van Vleck during the same era. Facade Greenwich Street The original structure was a six-story building with a fireproof limestone facade on Greenwich Street, measuring . The Rider's Guide to New York City, published in 1923, described it as having a "simple classic design". The facade facing Greenwich Street is of gray brick, and is divided into eight vertical bays. Five of these bays correspond to five three-story-tall large round-arch windows overlooking the main board room on the second floor; the National Park Service described them as "recall[ing] the airiness of the outdoor market". There is a corresponding pair of rectangular windows on the sixth floor above each round-arch window. The northernmost bay contains two windows on each floor, rather than an arched window spanning the second through fourth floors. The words are carved above the arched windows. Trinity Place The Trinity Place facade is about long, and is 14 stories and tall. It is designed primarily in the Art Deco style and is divided into seven bays. The facade is made of limestone, and the base is made of granite; this might have served to distinguish it from the neighboring Trinity Court Building to the south. The first floor facade is a limestone water table containing three entrances. The centrally located members' entrance had four glazed doors and a rounded frame, and previously contained a transom with glazed panels above the doors. To either side of the main entrance was a smaller entrance with three doors: the entrance to the north led to the elevator lobby, while the entrance to the south led to the nighttime clearing house and daytime branch (which later became a visitor's gallery). In the center bays, there are five long rectangular windows spanning the second through fifth floors, giving the Trinity Place
