Description

Castle Farm farmhouse is a medium-sized house that forms part of a complex of buildings within a medieval castle enclosure. It features a double pile plan with a central porch entrance. The structure is built of stone rubble and has a stone tile roof with flat stone coping, along with corniced end stacks and front and rear axial stacks. The house has two storeys, an attic, and a cellar.

The main frontage displays an embattled parapet that spans two-thirds of its width. Below this, there is a three-window range of 6/6 pane horned sashes, with two similar windows on the ground floor beneath a cambered arch on the left and in a blocked arch on the right. The central gabled entrance porch has a steeply pitched stone-tiled roof, prominent kneelers, and flat tile coping. The porch features a very narrow pointed arched moulded doorway with broach stops and a flagged floor. The main doorway is moulded in a Tudor arch style, with decorative spandrels and a studded ledged and battened door.

The right return, which overlooks the garden, reveals the double pile plan with two rectangular attic windows, although the glazing has been renewed. There are blocked or relieving arches, some with small windows that also have renewed glazing but retain their hoodmoulds. To the left, there is a large ground floor segmental arched head to a tripartite sash, a plain central door under a stone lintel, and an arrow loop to the ground floor right.

The rear elevation features more 6/6 pane horned sash windows across three storeys, a cellar opening, and chamfered round arched lights on the left. The left side elevation, which now serves as the main entrance, includes a lower whitened two-storey and cellar lean-to with mostly 4-pane windows, some of which are cambered arched. There is also a glazed awning supported on four cast iron piers and a large stack on the right. A large hopper dated 1926 is also present.

The interior was not inspected at the time of the survey on 2nd December 1997.
