Barn and Engine House Immediately West of Upper Cheddon Farm

The building is a barn and attached horse-engine house located immediately west of Upper Cheddon Farm, dating from the 18th century. It is constructed of stone rubble and features an asbestos tile roof with gabled ends, hipped over the engine house. The barn has a five-bay layout with a threshing floor in the central bay and a porch on the east front. The exterior of the barn has a symmetrical east front with a large gabled porch at the center, which includes double doors and a boarded gable. There are additional doorways inserted high up in the front wall on either side. At the rear, there is a large doorway in the center that is now boarded over, along with a smaller doorway to the left.

The horse-engine house is attached to the north end of the barn and is open-sided, supported by large stone rubble piers, with the east front pier exhibiting a pronounced batter. Of the five open bays, the two at the back have been blocked. Inside, the barn features a raised floor and an original five-bay roof with tie-beam trusses, butt-purlins, a tenoned diagonally-set ridge-piece, and a complete set of common rafters. The porch roof is also intact. The engine house contains a large tie-beam and butt-purlins supporting the principals, along with intact common rafters.
