Dwelling, Farmsteading, Sibster Farm

The South Range at Sibster Farm is a large farmstead complex arranged around a square courtyard, with parts dating from the late 18th century to the mid to late 19th century. The buildings are constructed of rubble with rubble dressings. The oldest section is the west range, which includes a kilnbarn that has a long elevation facing east and west. The kiln features a bow-ended gable at the north end, rising above the ridge as a tapering rubble inverted cone that ends with a circular apex vent. There is a square opening in the north end and a later doorway on the west side.

Inside, a later inserted boiler occupies half of the space, but enough of the original massive masonry remains to show the internal layout. This includes a flue vent in the south wall, a scarcement or kiln platform, and a blocked upper door in the south wall that once provided access to the kiln floor from the barn.

To the east, there is a second, later barn that runs parallel to the first and connects to it at the south, forming a U-shaped plan. The north face of this U-plan is filled with an early to mid-19th century hexagonal horse engine house, which features a later 19th century square chimney serving a more recent boiler. The later barn has a ramp leading to a wide entrance in the north gable.

The west side of the square is closed off by a byre range, while the east side is bordered by modern cattle courts. The south side is filled by an open-fronted fold that abuts the entrance to the square from the road, featuring six segmental-headed arched openings.

Most of the buildings are roofed with Caithness slate, while the older barn has a roof made of Welsh slates. Additionally, there is a small two-storey, two-bay house from the mid-19th century located on the east side of the steading range. This house is harled, has end stacks, and a slate roof, but it is no longer used as a dwelling.
