Description

Castle House is a 3-storey building with a 5-bay rendered front and an advanced 3-bay frontispiece. It features a low-pitched slate roof that is concealed behind a freestone blocking course on a wide cornice, with similarly dressed end chimney stacks. The building has 9 and 12-pane sash windows with cills, and the central bay has broadly spaced tripartite windows, while the second floor features Venetian-type windows. The entrance has a renewed broken pedimented doorcase with a dentilled cornice and reeded pilasters, leading to a large 8-panel door flanked by narrow lights.

The side elevations have flat Dutch gables, and there is rear access through rubble gate piers at the right end, along with a rubble chimney breast. The cross range to the right has been altered by Williams-Ellis, featuring sash windows with broader glazing bars that reach almost to ground level. The asymmetrical rendered rear includes cross ranges and voussoir lintels above the sash windows. A 19th-century colourwashed rubble former servants' hall extends east beyond a tall rubble chimney stack.

Inside, the house retains fine Regency interiors, including an entrance hall with barley-twist banding, cornices, and classically fretted architraves leading to massive panelled double doors. When folded, these doors create a ballroom at the front of the house. Smaller panelled doors lead to public rooms, with the dining room featuring blind panelling and an animal head cornice, while the drawing room has a dentilled cornice and a Regency fireplace with oval metal fastenings on the window shutters. An archway with a keystone and classical detail leads to the stairwell, which features a fine cantilevered staircase (with later support), wave moulded treads, and a curved handrail.
