Galestra Farmhouse including attached Byre

Galestra Farmhouse, which includes an attached byre, is a two-storey L-shaped farmhouse built in the third quarter of the 17th century, with a slightly later single-storey wing. The building is constructed of whitened rubble and features a slate roof with rubble gable parapets. It has end chimneys that are capped and have weather coursing, with the left chimney being larger and projecting, and battered at the rear. The main east-facing front is set behind a dwarf rubble-walled front garden adorned with decorative iron railings.

The central entrance features a 20th-century porch with a pitched slate roof and plain bargeboards, leading to a wide six-panel mid-Victorian door with glazed upper panels. To the left of the entrance is a large six-pane recessed sash window, and to the right is a smaller twelve-pane sash window, both from the 19th century and with projecting slate cills. On the upper floor, there are three nine-pane sashes located under the eaves. At the rear, there is a rubble outshut with a rubble parapet on the left, and a catslide porch entrance where it intersects with the rear arm of the subsidiary wing. Inside the porch, there is a 17th-century stopped-chamfered, pegged doorcase with a 19th-century boarded door and an additional door leading to the outshut. The right end chimney of the later wing is also made of whitened rubble and has a modern window. The rear features 19th-century four and twelve-pane sash windows.

To the left of the farmhouse is a flush, continuously roofed byre that is contemporary with the main building, featuring an old slate roof and a rubble gable parapet on the right. The byre has two plain entrances with stable doors and an entrance under the eaves on the right side. There are two dormers on the rear; the first, on the right, is higher and made of corrugated iron, while the left dormer has a catslide roof and barely breaks the eaves, with boarded doors.

Inside the main block, the left room has a main chamfered beam and a 20th-century fireplace set within a large inglenook opening, along with a boarded partition screen that is papered over. The rear pantry features 19th-century boarded partitions. The rear wing has a large stopped-chamfered end beam supported by a rough stone corbel, and the ceiling beams are decorated with grooves. The adjoining byre has a slate-flagged floor and a contemporary four-bay roof with pegged collar and tie-beam trusses.
