Description

Holywell House is a country house dating from the 18th century, with early 19th-century additions and renovations around 1900. The walls are constructed of brick, using English bond, predominantly Flemish Garden Wall bond, and some Flemish bond with blue headers. The curved walls use header bond. The roof is hipped and covered in tiles, featuring stepped eaves. The building has a wide front and projecting wings, with alterations and extensions creating a complex roofline.

The symmetrical south-west front has semi-circular bays on each side, and is two storeys high with a semi-basement. It features a 3-window arrangement (3 windows across, 1 window central). The windows are sash windows in reveals, with the ground-floor windows in each bay taller and with semi-circular heads. A doorcase, dating from the early 20th century, has a cornice supported by carved brackets, a pulvinated frieze, an architrave framing a semi-circular fanlight, and a half-glazed door. A flight of 10 spreading stone steps leads to the front door, flanked by wrought iron rails.

The side elevations are irregular and contain some more recent features. The rear elevation is plain, with wings extending from it, and a tall staircase window is visible in the recessed centre.
