Castle Farm with Attached Farmyard Wall and Outbuildings

Castle Farm, built in 1758, is a farmhouse and garden folly that is reputedly designed by the Duchess of Norfolk with assistance from James Paine in the Gothic style. The structure features coursed rubble and ashlar with ashlar dressings and slate roofs. It has quoins, an ashlar plinth, a plain ground floor band, and a moulded first floor band, all topped with coped battlements. The layout is courtyard-style.

The north range includes a central two-storey, five-bay pavilion with a central two-storey canted bay window. The central opening, which was once a doorway, has a Gothic ogee double arch moulded surround with a glazing bar sash. On either side are single similar sashes with moulded ogee heads, and beyond them are single ogee-headed niches. Above this, there are five smaller glazing bar sashes with four-centred arched heads. This pavilion connects to flanking stepped gable pavilions, each featuring a single ogee-headed glazing bar sash and a blank quatrefoil above, all within a large flush pointed arch. These pavilions are further linked by walls to two-storey corner towers, which have single ogee-headed blank openings with quatrefoils above.

The east and west ranges have high boundary walls with central and corner slightly projecting towers. The south range features corner towers and single lean-to cart sheds on either side of the central gateway. Inside the courtyard, there are various 20th-century buildings that are of no interest. The interior of the central pavilion includes a large ground floor banqueting room with ogee-headed windows and door surrounds, a four-centred arch leading into the bay, and a plaster vault ceiling with ornate foliate corbels.
