Barnston Manor Including Attached Farm Building On South-East

Barnston Manor, which includes an attached farm building on the southeast, is a manor house with origins dating back to the 13th century, and it was altered in the 16th century. The structure features rubble stone walls, with the front wall partially refaced in ashlar during the 16th century. It has stone slate roofs with coped gables and stone stacks that have moulded caps. The current layout consists of a hall with a cross-wing at the west end, which has an additional extension to the west at right angles.

There are remains of a screens passage at the east end of the hall, but no surviving evidence of a pantry or buttery. The cross-wing and its west wing are from the 13th century, with alterations made in the 16th century. The hall is dated to the 13th century according to a Royal Commission on Historical Monuments survey, but it lacks surviving features from that period. According to R. Machin, it is likely a 16th-century addition to a 13th-century first-floor hull-house, with the west wing serving as the original solar.

The building has two storeys. The west wing contains three blocked 13th-century lancet windows and two inserted 16th-century four-light stone mullioned windows. The cross-wing features a two-storey canted bay window that is six lights wide, with stone mullions and transoms, a hipped stone slate roof, and moulded string courses. The hall has a large projecting chimney stack, with a four-light stone mullioned window with a hoodmould on the ground floor and a two-light stone mullioned window on the first floor, both located west of the stack. The original door to the screens passage is located east of the stack, partially built up, with an inserted mullioned window. All windows are fitted with lead lights, including a two-light 13th-century window, originally shuttered, in the rear gable wall of the cross-wing.

Internally, the hall features 16th-century moulded intersecting ceiling beams, one of which has mortices for the original screen. There is a 16th-century stone fireplace with a moulded surround, and a corbel in the west wall likely supports a former stair to the upper floor of the cross-wing. A stone spiral stair is located at the rear of the cross-wing, and there are 16th-century stone arched fireplaces on both floors of the cross-wing.
