the house, only one room deep, is long and narrow, 86 feet in length by 18 feet in depth. in the front elevation, the central three-bay pedimented pavilion is flanked by four-bay wings. the bays are defined by shallow, two-story ionic pilasters. the walls of the pavilion and wings are in the same plane, since the pavilion does not project. the planar effect is emphasized by the wall sheathing, which is flush boarding, tongue-in-groove. the twelve flat pilasters rise with entasis from bases of double torus moldings to stylized ionic capitals. two string courses, one at first-floor ceiling height, the other below second-floor window sills, establish a horizontal orientation to balance the strong upward thrust of the pilasters.
