Description
The barn at Coetmor Farm is a Grade II listed structure, built from rubble stone and featuring a slate half-hipped roof. The large barn entry is located to the left of the center and is topped with a slate slab lintel. On the left side, there are three vent loops at the upper level and two below. Attached at the left angle are pig-sties, which are listed with other outbuildings.
To the right of the door, there is a two-storey range that includes one square window with a slab lintel positioned under the eaves, two ground floor loops, and one loop at the upper level. Additionally, there is a stable door with a slab lintel and a square loft window above it on the right side. The rear of the barn features outside steps leading to a loft door, which is sheltered by a hipped porch.
An added two-bay cart-shed is located to the right, also featuring a slate roof that is hipped at the west end. This cart-shed is supported by massive stone lintels and square piers.
