The house is now a historical tourist site because of its interesting architecture. It is known for its finely carved stonework, hand polished brick, intricate plaster moldings, and a wrought iron fence with palmetto and honeysuckle patterns. The greatest feature though is the rare, freestanding spiral staircase in the center of the front hall. The staircase supports itself through a distribution of weight on the bottom step and the ends of all the other steps. It is also a type of air conditioning that makes warm air flow up to the attic, therefore cooling the rest of the building. The staircase was based on a design by Minard Lafever titled, Modern Practice of Staircase and Handrail Construction. The house is on of Madison's most historically important buildings and has been listed as both a National Historic Landmark and a member of the National Register of Historic Places. It is available for tours by appointment only.
