Silwood Park and former stable block

Silwood Park is a large country house with a former stable block, built between 1876 and 1878 by Alfred Waterhouse. It is located in Sunninghill, originally on London Road, and is now used as a college. The house and stable block are constructed of red brick in English bond, with Bath stone dressings and tiled roofs, the roofs featuring fishscale tiles every third course and crested ridge tiles. The stables are of similar construction to the main house. The architectural style is Gothic.

The main house has two storeys with attics and a basement. Features include several large chimneys with offset heads and clay pots, a projecting plinth with a stone band above, a moulded string above the first-floor window heads, and brick corbelled eaves. The north-west front, which serves as the entrance front, is irregular and comprises four one-bay gables of different heights. A tall tower, spanning three stages, rises over the enclosed entrance porch, topped with a pyramidal roof and a large open lantern. The tower's upper stage features stone blank arcading with cusped heads and circular colonnettes, and brick corbelled eaves, separated by moulded stone strings. The entrance porch has a lean-to roof, engaged columns with leaf capitals, and is accessed by five stone steps. A five-bay conservatory, with a stone canted bay and end, is positioned to the right, featuring a stone parapet pierced with cusped openings, three-light windows with round heads, and a glazed lantern roof.

The stable block has a steeply pitched plain tile roof with several gables and a courtyard plan. A clocktower sits on the south-east side, and a spirelet is positioned on the north-west ridge. Sash windows are set within stone surrounds, and a large arched carriage entrance is located on the north-east side. The interior of the house includes a full-height lounge/hall with a balustraded gallery and coved soffit, a barrel roof with rooflights, a large fireplace with a hood at the north end and doorways with segmental-arched heads. The interior of the stables was not inspected. The house was built at a cost of £27,500.
