Architect Niles Llewelly Wickwire designed the courthouse in the Italianate style.

The courthouse's design features narrow arched windows with iron hoods, brick quoins on the corners, triangular pediments above the east and west entrances, and a bracketed cornice.

The roof is topped by an octagonal cupola with a clock facing each side of the building.
