Description

This is an 18th-century house, formerly a mill house, with alterations in the later 19th century and further refenestration in the 20th century. The first description details a building of coursed stone rubble with brick window dressings, quoins, and a plinth. It has a half-hipped roof with a tall central brick stack. The house originally had five windows, mostly 20th-century wooden casements, although the central first-floor window is a fixed casement with a pegged architrave. A 20th-century Dutch door is centrally positioned, protected by a gabled tiled hood supported on wooden piers. The left side has a tile-hung gable and a 20th-century window, while the right side features weatherboarding on the gable and a single-story extension with a tiled roof. There have been several gabled 20th-century extensions to the rear.

The second description notes that the house is built of stone rubble with red brick dressings and has an old tiled roof with brick chimneystacks. It is two stories high. The south, or garden, front features two windows with renewed wooden casements in cambered architraves, and a modillion eaves cornice. A late 19th-century gabled brick porch occupies the center, hiding the original late 18th-century cambered entrance behind a plinth. The east elevation exhibits ironstone galleting to the stonework and includes two 12-pane sashes to the right, alongside a double sash window beneath a large cambered brick arch. A cambered doorcase is present, with a later hipped weather porch. The north elevation also showcases galleting to the stonework, with a gable on the left and a hip on the right. A late 18th-century 16-pane sash window is situated under the hip, with two later casements to the ground floor beneath cambered heads. A blocked cambered opening is located under the gable. The west elevation features a late 18th-century 12-pane sash window on the first floor and a later extension of stone and brickwork on the ground floor.

Inside, a parlour boasts a late 18th-century brick cambered fireplace and a lead water pump enclosed in a wooden case. A cupboard has a plank door, and a two-panelled door leads to a brick-paved hall. A ledged plank door is on the ground floor, and a ledged plank door and a late 18th- or early 19th-century sash window are on the first floor. The roof in the western part of the house is late 18th-century, constructed with angled quoin struts, a collar beam, through purlins, and a ridgepiece, with some rough-hewn purlins. The eastern part of the house has a staggered purlin roof.

The third, brief description confirms a stone construction with red brick dressings, quoins, a dentilled eaves cornice, and a tiled roof, retaining original glazing bars. It is two stories high and has two windows.
