Built by the Harmony Society in 1891, by 1918, this building had become the offices of the Union Drawn Steel Company, and functions today as retail and office space. It is an imposing four-story, mansard-roofed, brick and stone office building. The stone veneer of the facade, the march of arches across both elevations, and the foliated capitals of its columns are all characteristic of Richardsonian Romanesque, at that time holding sway in western Pennsylvania.
