The district encompasses four buildings in the complex: the clerk's office (1924), the court house, the County Office Building, jail and the Dillard House (c. 1800).

Other buildings are the mid-19th century county treasurer's office and the John Bannister House.

It has a cross-gable roof with cupola and features a three-bay arcade, one-bay deep with five rounded arches, on its front facade.

The building is one of a number of county courthouses inspired by the architecture of Thomas Jefferson, who employed its builder Dabney Cosby in the building of the University of Virginia.
