The facade of 1 Wall Street's original section contains several decorative elements that make it appear as an "organic" design, rather than a machine-produced design. Walker said that 1 Wall Street would "have 200 thousand people looking at it from all sides" in a single year, including workers and pedestrians, and that they should have "mental relief and pleasure" when looking at the building. Walker also stated that in 1 Wall Street's design, he "tried to superimpose one rhythm upon a basic rhythm", and as such, he treated the facade as a series of "rhythmic motifs" in different sizes. Each of the bays is separated by curved, projecting piers that proceed to the top of the setback. Several piers also contain vertical incisions for emphasis. The windows of the original building had to be specifically designed with curved frames in order to fit into the facade.
