Ampherlaw Farmhouse

The property comprises a farmhouse dated 1850, along with later additions, and a complex of associated farm buildings arranged around a quadrangular courtyard. The farmhouse is a symmetrical, two-storey, three-bay rectangular structure, with buildings linked to the northwest and southeast to form the courtyard. It is built of squared and snecked yellow and grey sandstone with ashlar dressings, featuring a base course and raised ashlar margins. The farm buildings have crow-stepped gables.

The principal, southwest-facing elevation of the farmhouse has a central timber-panelled door, sheltered by a bracketed sloping stone canopy and a four-pane fanlight. A central gabletted dormer breaks the eaves, displaying a date plaque inscribed 'S 1850'. Square-headed dormers, also breaking the eaves and featuring projecting timber cornices, are situated in the outer bays. The rear elevation exhibits irregular fenestration and a central dormer. A 20th-century lean-to extension provides an entrance, and a small toilet block is located to the southeast. Modern, two-pane timber sash and case windows are present, along with newer timber windows in the extension. The roof is covered in grey slate, with two ridge stacks featuring clay cans and cast iron rainwater goods. The interior has largely been modernised, with a stone staircase.

The southwest steading range is a short range adjoining the northwest gable of the house, featuring two large windows and a grey slate roof, a flagstone floor, and a single ridge stack.

The northwest steading range is a long byre constructed of coursed rubble. It has a single sliding metal door to the north gable, with a stone lintel and small vent above, and a blocked slit vent to the south gable. Horizontal vents are located on the side elevations, and a double metal door and window are found on the south end of the west elevation. Numerous rooflights are present, and the roof is a slated A-frame structure with crow-stepped gables, including a single beaked skewputt on the north side. Ball finials are present, but missing from the south side. The interior contains a concrete floor, stalls with ceramic troughs, and metal wall-mounted bowls.

The northeast steading range is built of rubble with droved quoins. It formerly served as a milking parlour with a hayloft above, and includes a cartshed to the southeast. It has crow-stepped gables with beaked skewputts on the northwest side. There are two boarded doors on the ground floor and a double boarded door leading to the hayloft. The southwest elevation features two large modern windows to the left and two segmental headed open arches (one blocked) to the right.

The southeast steading range comprises two distinct buildings. The building to the northeast has a piended roof with alternating bands of square and fishscale slates on the southeast pitch; it also has an A-frame roof and a stone skew table, as well as a single door. The southwest section features a crow-stepped gable and two blocked single doors. A former smithy projects into the courtyard, with a crow-stepped gable and a gablehead stack.

Boundary walls are constructed of rubble with semicircular copes, with square-plan gatepiers.
