Built as the Alleghany Construction Company's store and office, this three-story palazzo-inspired building features many of the architects' hallmark design details, including a buff-colored brick facade, careful proportions, and a selection of classical ornaments—quoins, keystones, and projecting cornice—below the parapet. Shops and offices occupied the lower floors and railroad workers lived on the upper floors. The building was rehabilitated by the Allegheny Highlands Housing Alliance in 1998 for ground-floor commercial use and upper-story rental apartments.
