Description

The barn at Great Bottom Farm is a Grade II listed structure built from rubble stone and topped with a slate roof featuring a tile ridge. The south front faces the farmyard and includes an off-centre threshing floor with corrugated metal barn doors and a raised door-canopy that has a monopitch roof. The left side wall has two vent slits, followed by corrugated double-doors and a boarded door leading to a cowshed at the far left. The right side wall also has two vent slits, a blocked doorway, and a boarded window with a timber lintel that serves a lofted stable. The east gable features a square doorway leading to an upper pitching loft in the gable-head, along with a boarded entrance door to the stable on the ground floor.

Inside, the barn has a stone-flagged threshing floor and a 7-bay interior supported by collar and tie beam trusses with raking queen struts.
