Description

The Duke of Northumberland is a late 18th-century house located on Lower Square, Isleworth. Originally named The Duke of Northumberland and previously The Northumberland Arms, it is a stucco building with five windows across its main facade. The windows are double-hung sashes set within reveals and feature flat arches. A substantial central porch boasts a semi-circular archway with cornice moulding, surmounted by a cornice and blocking course. The porch provides access to a doorway with a radiating fanlight. A cornice runs along the top of the main facade, followed by a parapet which features "The Northumberland Arms" rendered in early 19th-century raised stucco lettering. The roof is a slate mansard with gable ends and three flat-topped dormers. The building is flanked by two-storey wings, identical to each other. Each wing has a single-story stucco ground floor with a central door and narrow sash windows on either side, topped by a cornice over a blocking course. The second storey, set back from the facade, contains a single sash window, and a band connects the window sills. A parapet and hipped slate roof complete the wing.
