William Clark House was designed by the firm of Trowbridge & Livingston, architects responsible for such landmark structures as the B. Altman & Co. Building and the New York Stock Exchange. The building is part of an outstanding group of Federal Revival red-brick town houses known as the "Pyne-Davison Blockfront" which extends along Park Avenue and between 68th & 69th Streets.
