13A And 13B Blantyre Mill Road, Bothwell

This is a later 19th century house, with subsequent alterations and additions. It's a symmetrical, rectangular two-storey building with three bays, built in an Italianate style. A flat-roofed porch has been added to the east side, and there's a single-storey addition to the rear. The house is constructed from meticulously crafted pink ashlar sandstone, with polished dressings. A base course runs along the ground level, and decorative cast-iron balconies are attached to the first-floor windows. There's a cill course to the first floor, and a deep, bracketed eaves line.

The main (north) elevation has three bays, with a recessed single-bay porch on the left. The porch features a moulded door surround with a deep bracketed cornice, sheltering a two-leaf timber panelled door with a rectangular fanlight above. A bipartite window sits above the porch at the first floor. Bipartite windows are positioned at ground level, with triple and bipartite round-arched windows featuring columnar mullions above them. A modern timber panelled door with windows flanking it is present on the porch.

The east elevation shows two bays, with a tall window in the centre of the advanced porch, and a window at ground level in the bay to the left. A wallhead stack is visible.

The west elevation includes a single-bay addition to the rear of the main block, with bipartite windows at each floor, and a central wallhead stack. An L-shaped, single-storey projection extends to the rear with a modern door in the angled bay, and a window in each of the remaining bays.

The rear (south) elevation has three bays, with a piend-roofed single-storey block spanning the central and right bays, with a window in each bay. There's a window in each bay above at the first floor. An L-shaped projection is present at ground level, with a window above.

The windows are mostly timber sash and case, with 6-, 4-, and 12-pane windows to the rear and sides. A modern window is located in the L-shaped addition. The roof is a grey slate piended roof, with slate on the additions. A modern felt covering is used on the garage and porch. Ashlar coped stacks are on the east and west wallheads, along with cast-iron rainwater goods – some replacements are uPVC on the rear.

The interior was not inspected in 1997.

Two pairs of square-plan gatepiers, with rounded corners, channelled faces, a string course, cornice, and shallow pyramidal caps, mark the boundary. The piers for 13A are painted. A squared and stugged sandstone boundary wall has a ridged ashlar cope.
