It is a three-story structure, faced in brick, with modest Classical Revival styling.

The building is roughly rectangular in shape, divided into three sections, one of which projects slightly.

The appearance of this section is one of a portico, with pilasters supporting a triangular gabled pediment.

The building is, despite its relative architectural simplicity, one of the largest and most architecturally distinctive buildings in the county, and has housed most of the county offices and court facilities since its construction.
