Former Crosshill Annexe, Colinhill Road, Strathaven

The Former Crosshill Annexe, located on Colinhill Road in Strathaven, was built in 1850, with an east wing and bellcote added in 1875. This single-storey, 7-bay asymmetrical U-plan former school features two prominent gabled ends and a flat-roofed hall addition situated between them. The building is finished in painted render with painted sandstone dressings, and includes a base course, an eaves course to the central hall, plain margins around the openings, blind windows, and a keystoned oculus at the gableheads, along with strip quoins.

On the principal elevation, the central 3-bay hall addition has deep-set, 2-leaf, part-glazed timber doors located in a slightly recessed bay at the center, flanked by two small windows on the right. Each side of the hall features a window in every bay, with two additional windows in each gabled bay on the outer right and left. Above these are blind oculi, and the right gablehead is topped with a bellcote.

The windows were originally boarded and were formerly steel-framed with small panes and side-opening casements. The roof is covered in grey slate, with a felt covering on the hall addition. The building also features ashlar skews, ovolo-moulded skewputts, a corniced ashlar ridge stack, and cast-iron rainwater goods.

The interior, which was not fully seen in 1998, has a simple design with most classrooms retaining their original timber doors, timber dado, and timber floors.
