Technical Block, Keil School, Helenslee Road, Kirktonhill, Dumbarton

The Technical Block at Keil School on Helenslee Road in Kirktonhill, Dumbarton, was designed by architect John Honeyman and is dated 1865, as noted on the rainwater head. Originally a stable block, this building features a Gothick style with stugged ashlar coursers and polished dressings. It consists mainly of two single-storey wings with lofts, arranged in an L-plan that forms a churchyard.

The courtyard elevations have a continuous hood-mould raised over the ground floor openings. The west wing is asymmetrical, featuring two 2-centred-arched cart openings that have been altered to windows, flanked by doors and one outer window. Above the hood-mould, there are diminutive paired lancets. A loft door with a dovecot is set in an arched moulding within a gabled dormer head, and there is a corbelled oriel supported on a shaft with cusped lights on the south gable.

The north wing includes a former door that has been converted into a window, flanked by lancets, all recessed in arcaded pointed panels. The eaves are moulded, and there is a conical-roofed, two-storey angle tower on the right, which features a square-headed roll-moulded door and is banded at the eaves level, with a clock and two small lights above. The building also has some flat-roofed six-pane dormers and crow-stepped gables throughout, with slated roofs. Each gable has a small lean-to and hood-moulded cusped lights, with three gables on the west elevation.

The courtyard is cobbled and partially enclosed to the south and east by a stugged ashlar wall. There are two square polished ashlar gatepiers with gabled caps and cast-iron lamp brackets to the south. A modern extension to the north is not included in the listing.
