Description

Kempthorne House is a house in a row, likely dating from the late 18th to early 19th century, but substantially remodelled in the late 19th century. The front is rendered, with slate sills and an asbestos slate roof, featuring a gable end on the right and adjoining No. 5 to the left. The house was originally conceived with a plan of two front reception rooms, a passage leading to a central stair, and rear service rooms, later extended to the rear in the 20th century. It has three storeys and a two-window frontage onto St Peter’s Hill. A central doorway has a panelled door. The ground and first floor have late 19th-century canted bays with horned sash windows and hipped slate roofs. Original openings remain on the second floor, with an original hornless twenty-pane sash on the left and a horned copy on the right. A 20th-century folding canopy covers the ground floor openings. The interior has not been inspected. The property is included for group value.
