Garden Wall, Pavilion and Entrance Gates to Car Park at Barnett Hill

The garden wall, pavilion, and entrance gates to the car park at Barnett Hill were built in 1905 by Arnold Mitchell. The structure features purple and brown brick walls with ashlar dressings on the pavilion and ribbed brick dressings on the walls. The wall is approximately 100 meters long, attached at one end to the service wing of the house and ending in gate piers and the pavilion to the south. The wall stands about 6 feet high on the west side and approximately 12 feet on the east side. It has stone coping along the top and five stone and gauged brick banded piers that alternate with diamond-shaped stone panels.

At the southern end of the wall, there is an arched niche with gauged brick lining, flanked by square piers of the gateway. The wrought-iron gate features a scroll and urn crest, with stone urns on the piers above modillioned capitals. A niche south of the gateway connects the wall to the square pavilion. The pavilion is a single storey over a basement, with panelled angle piers made of ribbed red brick on stone plinths. It has a wooden modillioned eaves cornice beneath a ribbed copper domed roof. The west side has a three-quarter glazed door with flanking lights, and the basement is open to the south side, featuring a keystoned arch leading to a half-glazed basement door.

To the east of the pavilion, a return wall extends across the garden with four scalloped bays on either side of a central gate, featuring piers similar in design to those previously mentioned. The rectangular pavilion at the east end has a gable end banded in brick and stone, topped with a copper half-domed portico on stone Doric piers and dentilled eaves. The north wall of the car park is attached to the house at the west end, featuring a central gateway flanked by piers on moulded plinths and topped with sphere finials, along with scroll-topped wrought iron gates.
