Description
This is a late Georgian-style house, likely dating to the late 18th century. It consists of a three-storey main house, with a two-storey wing to the left and a single-storey wing to the right. The walls are rubble stone, rendered with stucco. The main range has a hipped roof concealed behind a plain parapet, decorated with a moulded cornice and brick stacks on either side. It has a three-bay front with windows featuring eared architraves. The right and left windows on the front elevation have nine panes of glass, while the central window on the upper floor is tripartite (three windows grouped together), and the central window on the middle floor has twelve panes with a tripartite arrangement. Bow windows have been added to flank the doorway on the ground floor. A porch features angle pilasters and a moulded parapet, and the double doors have a raised fielded panel below, flanked by similar-panelled and glazed sections. An overlight (small window above the door) has radial glazing.
The two-bay wing on the left side of the house mirrors the detailing of the main range, with a bow window on the lower floor, and the left bay set back with a half-lit door and an overlight with radial glazing. The side and rear elevations of the main house are distinguished by a continuous plat band. The left side wall behind the wing has two windows with cross windows in the middle and upper storeys, alongside sash windows similar to those on the front. The rear elevation has three bays, with openings offset to the right. The centre has tripartite sash windows on the upper and middle floors, flanked by narrower sash windows that serve as service rooms to the left. A lean-to structure is centrally located on the ground floor, featuring a half-lit panel door with margin glazing, flanked by narrow sashes. A further lean-to extends to the left of centre, continuing around to the right side of the house. The four-window right side wall is the service end and has simpler windows. The single-storey wing has two windows on its front, with a sash window left and a replaced window right, as well as further sash windows on the side and rear walls.
Inside, the central hall features a curving open-well staircase with ornate iron balusters.
