Scoulag Cottage, Mount Stuart House

Scoulag Cottage, designed by Robert Weir Schultz in 1898, is a single-storey lodge in a baronial vernacular style, situated on a sloping site between two roads. The building features an asymmetrical triangular plan with a flat-roofed, three-bay bowed projection to the south and a canted, two-sided end to the north. A full-height engaged entrance tower is recessed to the southeast, and there is a basement at the rear. The exterior is finished in whitewashed harl with polished Gourock sandstone dressings, including moulded coping and eaves course, an architraved door-surround, and part-boarded timber gabled dormers. Painted shields are attached to the south bow, and there is chamfered coping at the sandstone entrance forecourt.

On the southwest (entrance) elevation, an iron-studded boarded timber door is set into the conical-roofed entrance tower, which is recessed to the outer right. The door features an architraved and roll-moulded surround dated "AD 1898," with a painted shield centered beneath an angled pediment topped with a thistle-shaped finial. A single window is aligned at the first floor. The forecourt at the front is enclosed by balustraded walls. To the left, there are three regularly spaced bipartite windows in the advanced bowed projection, with painted shields beneath the coping, and a small bipartite window centered in the gabled dormer above.

On the northwest (side) elevation, there is a bipartite window at ground level, offset to the left of center, and a small bipartite window centered in the gabled dormer above. The cottage features small-pane leaded timber casement glazing and a graded slate roof with Gourock sandstone ridge dressings and original decorative rainwater goods. A coped, whitewashed harl six-flue central ridge stack with circular terracotta cans completes the exterior.

Inside, the cottage includes timber skirting boards, timber panelled doors, replacement fireplaces, and a spiral stair. The living room boasts an impressive bowed end.
