Horsemill, Garson Farm

Garson Farm is a 19th-century farmhouse and associated agricultural buildings located to the east of Garson House (listed separately). The farm complex comprises a two-storey farmhouse, a barn and byre range, and a circular horse mill. The farmhouse is constructed of harl-pointed rubble with concrete lintels and ashlar cills. It has a flat-roofed, single-storey sun room/entrance porch on the south side. Modern barn ranges are situated to the south. Replacement four-pane timber sash and case windows are present throughout, along with a Caithness slate roof, a stone ridge, corniced rubble gablehead stacks to the east, and uPVC rainwater goods.

The north (principal) elevation of the farmhouse features an enlarged window at ground level in the left-hand bay, and a window at first floor above. To the right, there is a window at each floor. The south (rear) elevation has a flat-roofed sun room with a door spanning the central and left-hand bays, and first-floor windows above each bay to the right. The east side is a blank gabled elevation with a pitched greenhouse abutting the ground floor, and a gablehead stack above. The west side is gabled with a first-floor window offset to the left.

The barn and byre range is three-bay construction, grouped 1-2, with a boarded door offset to the left of the centre of the byre range, and a window at ground level on the left of the barn elevation. A boarded door is situated to the right with a boarded hayloft door above. The west elevation is six-bay, grouped 1-5, featuring a barn elevation to the left with a first-floor window. A boarded door leads to the left of the byre range, with windows in each bay to the right. The circular horse mill abuts the junction between the byre and barn centrally. The north elevation shows a gabled side elevation of the barn with a window offset to the right at ground level. Predominantly four-pane fixed timber-framed windows are set within a Caithness slate roof with a stone ridge.

The circular horse mill is constructed of harl-pointed rubble with a conical roof. It has two four-pane windows evenly spaced on the north side, a blocked doorway with a small-pane strip light along the top edge to the northwest, a two-leaf timber doorway to the southwest, and a smaller doorway to the south. The roof is banded with modern felt at the apex, asbestos tiles in the central section, and Welsh purple slate below. Internally, the mill features fanned horizontal tiers of exposed timber rafters and joists with a central vertical support beam, a horizontal wallhead support beam, and close-set tile batons beneath the Welsh slate.
