The foundation of the building, the lower level walls and the lower columns are constructed of coral stone. The upper floor is of wood frame construction. Washington Place conforms to period French Creole Greek Revival houses that were built along the lower Gulf-Coastal region of the southeastern United States. The home was constructed with an almost square core surrounded by a peristyle, a two tiered verandah, Tuscan columns on its upper floor, and a hipped roof. The interior of the home is arranged in a traditional Georgian floor plan, with four distinct parlors on the first floor and four bedchambers on the second floor.
