Designed by the Albany, New York, firm of Fuller & Wheeler, the building exhibits such character defining features as rock-faced granite and sandstone, decorated moldings on the face of the arches, clustered arches with masonry mullions and transom bars, steeply pitched hipped roof, narrow eaves, finials, wall dormers, one-over-one sash in deeply recessed window openings, and a deeply set main entry behind a massive stone arch.  Semicircular arches are a defining feature of the Richardsonian Romanesque style.  The architects may have used Gothic Revival style arches to highlight the ecclesiastical status of the building.
