Craignaught Farm, Dunlop

Craignaught Farm is an early 19th-century farmhouse incorporating fabric from the mid-18th century, with some 20th-century alterations and additions. It occupies a slightly sloping site and is arranged as a 2-storey, 3-bay gabled farmhouse, with byres forming a U-plan courtyard to the northeast (front). The farmhouse is constructed of painted whinstone rubble with sandstone ashlar dressings, and some cement rendering. A base course, eaves course, and quoin strips are present, along with raised window margins and long and short droved quoins to the byres.

The house has an off-centre, half-glazed, non-traditional timber-panelled front door within a possibly later Doric-pilastered doorpiece, approached by three stone steps. The window arrangement is regular on the front elevation. Byre wings adjoin the northwest and southeast gables. The southwest (rear) elevation has irregular fenestration, including a window illuminating the central staircase.

Original 12-pane timber sash and case windows are found in the northeast (front) elevation; the rear windows have Victorian 4-pane and plate glass glazing. Ashlar-coped skew details are present only on the front elevation, and there are square skewputts with rosette detail. Corniced ashlar stacks are a feature, along with assorted clay cans and a graded grey slate roof.

The interior includes a curved stone staircase with cast-iron balusters and a mahogany rail. The hall contains a ceiling rose and a filled-in archway with key-blocked ashlar margins. A decorative cornice is found in the upstairs drawing room, and the interior doors are timber-panelled.

The northwest byre, likely a former longhouse, dates to the mid-18th century with later alterations. It is cement-rendered with painted ashlar dressings. It has an asymmetrical gable facing northeast and a piended roof to the southwest. A half-glazed timber-boarded door and bipartite window face the courtyard. The northwest elevation features an eaves course, a half-glazed timber-boarded back door, and irregular fenestration. Two datestone lintels are present: "IG 1808 MG" to the left of the door, and an incomplete inscription, partially obscured by a lean-to addition, which reads "[Jam]es Gill[mour] Agnes Gillmour May 28 174[7]".

The southeast byre, dating to the early 19th century, is L-plan with a gable facing northeast and a piended roof to the southwest. It includes timber-boarded doors and a blocked cart entrance to the courtyard, along with square and slit windows to the rear.

A former threshing barn, situated to the northwest of the house, is constructed of cement-rendered, random rubble with sandstone ashlar quoins and a graded grey slate roof. It has timber-boarded doors.
