Gavinburn Farm, Great Western Road, Old Kilpatrick

Gavinburn Farm, built in the mid-19th century by William Burn, is a farmhouse with associated farm buildings located on Great Western Road, Old Kilpatrick. The farmhouse is a two-story, three-bay L-shaped structure, originally designed as a square farmhouse with a two-story, gabled wing extending to the northeast. Later, two single-story extensions with flat roofs were added to the north side. A group of farm buildings is situated to the northwest, including a single-story, multi-gabled range of barns and cartsheds with a principal gabled elevation facing south, and a separate stand-alone barn.

The farmhouse is constructed of snecked and coursed, stugged and squared rubble stone, with long and short stugged ashlar quoins featuring polished strips. Openings have lugged and tabbed, stugged ashlar surrounds with ashlar mullions, splayed margins, and a plain projecting eaves cornice supported by rounded stone corbels. The eaves overhang with timber brackets and plain bargeboards. The barns and cartsheds also use snecked and coursed, stugged and squared rubble for much of their walls, with random rubble at the sides and rear, and sandstone ashlar dressings.

The south, or principal, elevation of the farmhouse features three bays arranged symmetrically. A recessed central entrance bay contains a timber-boarded and glazed lean-to porch with plain side lights and a fanlight, with a gabled dormer above. Flanking the central bay are wide gabled bays with tripartite ground floor windows and bipartite first floor windows.

The west elevation is two bays wide, with bipartite windows on the ground floor in both bays. There are gabled dormers with bipartite windows on the first floor. A late 20th-century flat-roofed conservatory and garage are recessed to the left, and the northeast wing is further recessed.

The north elevation presents a three-bay advanced gabled section with a narrow central bay flanked by gables. The northeast wing has a two-story gable end with a shallower roof pitch than the main portion. Late 20th-century garage and roughcast conservatory extensions are located to the north and west of the wing.

The east elevation is four bays wide, arranged as two bays paired together. It has a narrow window at ground floor left, a tripartite window to the right, and two widened windows to the far right (altered in the late 20th century). Bipartite breaking eaves dormers are located centrally, with two further dormers to the right. A single-story brick lean-to garage extends to the far right.

The farm buildings consist of a four-bay cartshed and barn range featuring two segmentally arched cartshed openings with ashlar voussoirs in the central bays. A large square opening with a steel lintel is located at the far left, and two narrow windows are at the far right. Concrete skews are present on the gables, and a later metal lean-to shelter is attached to the west elevation. A single rectangular-plan barn stands to the east, featuring two ground floor openings and a single, central opening to the loft.

The roofs are pitched and covered with grey slate, with grey slate also used on the dormers. The farmhouse has tall, corniced and shouldered ashlar stacks on the east and west ridges, with indented corners and circular clay cans. Smaller, rectangular gablehead stacks are located on the northeast corner and on the north wing. Most of the windows are currently PVCu, designed to resemble traditional materials.
