Description

The coach house and stable block, dating from the 18th century, forms a symmetrical U-shaped arrangement facing south, situated at Gyrn Castle. Constructed of rubble stone with slate roofs, the building comprises a long east-west central range flanked by parallel ranges to the left and right. The central range has a hipped roof topped with ball finials. The front elevation retains arches for coach entrances, although a wide opening supported by a timber lintel has been inserted beneath one arch. A former loft space above now features three half dormers and a chimney stack on the right side. Each wing displays a stone cupola with swept caps on their outer ends.

The left wing, facing a small courtyard, features two boarded doors and a horizontal-sliding sash window, both set within segmental stone heads. The upper storey includes an octagonal window with a casement on the left and a shuttered opening with a polygonal head on the right. The lower storey of this wing has a rounded angle on the left side. A stable lean-to has been added behind this wing, with a stable door, a horizontal-sliding sash window, and an inserted top-hung casement window on the south-facing wall. The rear of this wing has a stable door. Extending to the north side of the central range is a brick addition.

The right wing mirrors the left, with two boarded doors, a horizontal sash window, a shuttered opening with a polygonal head in the upper right corner, and a smaller inserted opening in the upper left. Two narrow vents are located below the eaves on the south wall. A rear lean-to on this side features a stable door and a single segmental-headed sash window. Further to the right (north) is a taller, two-storey, single-bay wing integrated into the end wall of the central range, with a boarded door to the left and a small, fixed, iron-framed window in the upper centre. A chimney rises from the northeast angle. The rear of the central range incorporates two half dormers, a sash window to the right of centre, and a doorway in a half-glazed porch in place of a sash window to the left of centre. A modern hay store projects from the right (west) end of the building.
