St Mary's Primary School And House, Raploch Road, Larkhall

St Mary's Primary School and House, located on Raploch Road in Larkhall, was built around 1872 and has undergone later alterations and additions. It is a single-storey, three-bay, gabled primary school designed in an ecclesiastical style, originally serving as a combined church. The building is constructed from snecked cream sandstone rubble with droved and polished dressings and features a base course. The pointed-arched openings have chamfered reveals and aproned cills, with buttresses on the west elevation that include trefoil brackets at the eaves course.

The north elevation, which is the principal front, has a grouping of bays in a 2-1 arrangement. It features three tall windows evenly spaced on the gabled block to the right, with a decorative cross above the gablehead. There is a window in each of the bays to the left.

The west elevation was originally designed with eight bays but now has six due to the addition of a flat-roofed single-storey linking block extending at right angles from the outer right bays. Each bay has a bipartite window, with pointed arches in the two outer left bays and a single window in the bay to the right, next to a projection.

The east elevation consists of eleven bays arranged in a 1-3-3-3-1 grouping. It features two pointed-arched windows evenly spaced in the advanced finialled gabled block at the center, with a crucifix motif above the gablehead. Each piend-roofed addition on either side has a window, and there are three closely spaced windows in each recessed block flanking the center. The outer left and right advanced gabled bays each have a tall tripartite window, and there is a tall wallhead stack to the left of the right gable. A memorial panel from 1902 is located in the gablehead to the left.

The building includes timber sash and case windows, as well as hopper windows. The roof is covered with grey slate and features slab skews, a tall ashlar stack on the east side, stylised thistlehead/shield motifs on the skewputts, finialled octagonal ridge vents, and cast-iron rainwater goods.

Inside, the school features timber panelled architraved doors, some of which are part-glazed, along with tall fanlights and timber skirting boards. The hallways have vertical boarding up to the height of the dado rail, and there is a part-glazed timber panelled folding screen that partitions the main hall.

To the north of the main building, there are gatepiers and boundary walls. The gatepiers are square-plan, chamfered ashlar with plinths, swept cornices, and shallow ogee caps. The boundary walls are made of squared sandstone rubble with stugged curved ashlar coping.
