Avonbank House, Avonbank Road, Larkhall

Avonbank House, located on Avonbank Road in Larkhall, was built in 1908, likely on an earlier site. This two-storey, three-bay house features a near-symmetrical design with paired half-timbered gables and a four-light canted bay window with a piend roof on the ground floor to the left. The exterior is harled with cream sandstone dressings and has applied timber framing on the gables. A cill course is present at the first floor, with plain margins around the windows and strip quoins.

On the east (principal) elevation, there are two stone steps leading to an architraved doorpiece, which contains two-leaf timber panelled doors topped by a small-pane fanlight. Behind this is a part-glazed timber panelled vestibule door with a rectangular fanlight above. A three-light window with a swept canopy is located on the first floor above. To the right, there is a three-light window on the ground floor and a bipartite window above it on the first floor, with a shouldered gablehead stack above. To the left, a four-light canted window is found on the ground floor, with a bipartite window above on the first floor.

The west (rear) elevation has an irregular arrangement of windows and features a wide M-gable with flat-roofed additions projecting to the west on the outer right. The house has timber sash and case windows with small-pane upper sashes, along with some casement windows located at the rear and in the additions. The roof is covered with grey slate, including the canted window, while the flat-roofed additions have a modern felt covering. There is an ashlar coped stack to the east, and tall wallhead harled coped stacks to the north and south. The twin gables have plain bargeboards, and cast-iron rainwater goods with a dated hopper are present on the east side.

Inside, the house features timber panelled architraved doors, timber skirting boards, and decorative cornices in the main rooms on the ground floor. The dining room includes a canted window flanked by panelled pilasters.

The boundary walls consist of a squared sandstone rubble wall with a curved ashlar cope running along the south side of the garden. At the southeast entrance to the garden, there is a square-plan stop-chamfered sandstone pier on a plinth, topped with a cornice and round-arched cap, along with replacement wrought-iron gates and railings.
