Description

This barn, located approximately 11 metres south of Wallon House, dates from the late 16th century to early 17th century and was refurbished in the late 17th century to early 18th century. It is constructed of cob on stone rubble footings and has a corrugated iron roof, which was originally thatch. The barn is a tall threshing barn facing northwest. The original front doorway is positioned to the right of centre and is flanked by short projecting midstrey walls. Both this doorway and the opposing rear doorway are now blocked. A new doorway has been created on the front left of centre between a pair of secondary cob store rooms. The roof is hipped at both ends. Inside, the barn is open to a six-bay roof. The two left trusses are original side-pegged jointed crucks with threaded purlins and an unusual double ridge. The remaining three trusses are replacements from the late 17th to early 18th century, featuring A-frames with pegged lap-jointed collars. This barn is notably large for its early date and is part of a charming group of listed farm buildings in front of Wallon House.
