At right is the kitchen, joined to the main house (at center) with a hyphen that served as additional living space for Thomas Stone's siblings and their families. At left is an outbuilding moved closer to the house to serve as an office for Stone, who was a lawyer. The center house was gutted by fire in the 1970s but the interior walls and roof were reconstructed by the Park Service. The outer walls are original.
