Casterton House, Ha-Ha Wall, Gates And Railings

Casterton House, along with its ha-ha wall, gates, and railings, dates from the late 18th century and was refronted and refitted around 1830. The building features an ashlar façade with red brick and slate roofs, topped by a parapet at the front. It has two stone gable stacks, with the left one reduced, and includes a copper-roofed verandah with cast iron railings and gates.

The house is three stories tall with a three-bay front that has a plinth, a first-floor band, and a parapet. The central bay is slightly advanced, flanked by end pilasters. On the ground floor, there is a verandah supported by slender cast iron columns featuring segmental arches and decorative spandrels. The central entrance consists of a half-glazed and panelled door with a fanlight, all set within a semi-circular moulded stone surround. This door is flanked by single canted bay windows, which have plain pilasters at the corners.

On the first floor, there are three plain sash windows with moulded stone architraves and cornices. The second floor has three similar windows but without cornices. To the left, there is a lower two-story single bay recessed wing, which contains a doorway with a moulded stone architrave and a narrow hood supported by scrolled brackets. Above this doorway is a sash window with a plain apron and moulded architrave. To the right, there is a single-story service wing with a stepped parapet.

Inside, the house retains a fluted stick baluster staircase with a wreathed handrail, a carved open string, and a fluted newel post. The contemporary joinery includes fluted architraves, roundels in the angles, a semi-circular hall arch, and a moulded plaster cornice. In front of the house, a semi-circular brick ha-ha wall with limestone copings supports a cast iron fence featuring octagonal panels, anthemia, and pierced square piers at the side gates.
