The rear side has loops on the left and center, a low double door with a timber lintel on the right, and a blocked low door to the left of center. The south gable end has similar loops and remnants of dove holes with stone shelves, along with a mark indicating the roofline of a demolished addition.

Inside, the barn has a six-bay roof supported by pegged oak tie-beam and collar trusses, all of which are numbered.
