Outbuilding Immediately to North East of Upcott Barton

The outbuilding located immediately to the northeast of Upcott Barton is possibly a former chapel, dating from the early 15th century and remodelled in the 17th century. It features cob and rubble walls and a gable-ended slate roof. The building has a rectangular one-room plan with no evidence of a fireplace. The roof structure, ceiling beams, and first-floor window are from the 17th century, indicating that the building was remodelled during this time, possibly changing its function from a chapel to a two-storey structure.

The exterior is two storeys high with an asymmetrical front. To the right of centre, there is a four-centred hollow chamfered granite medieval doorway, above which is a large inserted loading hatch. To the right of the doorway is a 17th-century three-light ovolo-moulded wooden mullion window. The left gable end features an original two-light wooden mullion window with trefoiled heads, although the dividing mullion has been removed.

Inside, the building has 17th-century roof trusses with straight principals, onto which the collars have been halved with notched lap-joints. The ceiling beams are also from the 17th century, although the first floor has been removed. This building is an unusual survival of an early non-domestic structure, with a strong suggestion that it was originally a chapel.
