West Wing to Belton House and Attached Boundary Wall

The west wing to Belton House, along with an associated boundary wall, forms part of the West Court. The west range dates to 1685-1688 and was designed by William Stanton, Master Mason, for Sir John Brownlow. A later 19th-century north range was added for the third Earl Brownlow, incorporating a 17th-century doorcase.

The west wing is constructed of ashlar and coursed squared stone, with a hipped Westmorland slate roof. The west range features an octagonal wooden cupola with a clock dial, round arched openings, a leaded ogee dome, and a finial. There are two large coped ashlar ridge stacks, two similar side wall stacks, and four smaller rear wall stacks, along with a plinth, flush quoins, and modillion eaves. The west range has a half-H plan, including a moulded elliptical carriage arch with imposts and a moulded keystone, and a pair of panelled wooden gates. It has 3 windows on each floor to the right, and to the left, 4 windows above 3 windows. A 6-panel door with an overlight, set within a surround similar to the windows, is also present. Five box dormers are above. The rear of the west wing has four dormers. Rear wings have regular fenestration with 5 windows to each floor and 4 dormers.

The north range includes a shaped round arched central gable and a moulded round arched doorway with a broken segmental pediment, flanked by smaller round arched niches, which contain figures. The original door has been replaced by a larger niche. To either side of the doorway are three windows, with four dormers above. Below are two windows on each side, followed by a door.

A boundary wall, approximately 70 by 30 metres, is attached to the southwest rear wing, enclosing a rectangular service yard. The wall is constructed of coursed squared stone with slab coping and ashlar corner piers with ball finials. Two doorways are located on the north side.
