Former Barn at Pentre Evan Farm

The former barn at Pentre Evan Farm is a two-storey building constructed of rubble stone with a slate roof, facing north. The building features dressed grey stone surrounds for the door and older window openings, rough quoins, and boulder foundations. The roof was covered with grouted slate in the 19th century but was likely originally thatched, as indicated by the projecting rugged stones at three-quarters height.

To the right of the center, there is a tall and broad segmental arched doorway with voussoirs at the head and a continuous chamfer. A pedestrian doorway is located immediately to the left, featuring a monolithic segmental pointed head. Another similar doorway on the right has a more acutely pointed arch and relieving arch stones above. Other openings display similar stonework, including a rectangular window above the left pedestrian door and a slit opening to the left of the same door. There is one additional window on the first floor to the right, occupying the site of a blocked opening with a modern timber lintel and original stones to the left jamb. A modern window is also present on the ground floor to the left.

The east end has outside stairs leading to a door with a monolithic lintel; while the stairs are modern, they are located where stairs were shown in 1867. The west end wall has two grey stone jambs that are blocked in.

At the rear, there is a large cambered arch with voussoirs, possibly from the 19th century, while the rest of the structure has been largely rebuilt in 1990. The rear features two 20th-century windows to the left and two to the right, each with heavy stone lintels, as well as two first-floor windows from the 20th century with timber lintels, one of which has grey stone jambs that appear to be original.

The barn has been converted into a hostel with an inserted floor. Previous inspections revealed that the wall thickness was reduced at about five feet, with crude corbels suggesting a sunk ground floor. The first floor has a 10-bay roof supported by arched collar trusses with arched spurs at the base, which are smoke blackened towards the west end, where a chimney was present in 1867. The roof also features butt purlins and slightly chambered collars.
