Architect Edward Stotz, of Pittsburgh, gave Sistersville a Colonial Revival building that takes full advantage of the street-bound diamond lot originally intended for the county courthouse. As all four sides are equally visible, all have almost equal importance in the design. A broad, three-sided bay centers each facade, creating a complex footprint—something on the order of a diamond within a square. Rising above a stone-faced basement story, the two-story brick structure has a heavy modillioned cornice and a hipped roof. Originally a cupola stood at the center of the roof. Splayed window lintels, brick arches, and a belt course provide decorative touches.
