Description
House. Dating from the 14th to 15th centuries, the central block was originally a hall, significantly altered and extended with a cross wing added in the 16th century. A 17th-century cottage was incorporated at right angles to the west, and a 20th-century linking block now joins the buildings. The house is constructed of coursed rubble stone, with a timber-framed gable end to the cottage. The main block has an old tile roof, while the cottage roof is covered in shingles and slate. A large stone stack is located on the north side of the hall, featuring two square brick shafts set diagonally. Similar paired shafts are present on the centre and side of the cross wing and on the south gable of the cottage, with a single shaft to the west gable of the hall.
The south front has four irregular bays with 18th-century barred sash windows beneath timber lintels. A paired casement window is on the ground floor of the left-hand bay, with a first-floor dormer above. The second bay features a projecting gabled porch with small windows to its side walls, set in dressed stone surrounds with cornices. A modern outer door leads to an inner door of old oak, boarded and studded, set within a moulded frame. The right-hand bay is gabled and projecting. A modern single-storey extension is connected to the left. The irregular east front displays three sash windows on the ground floor, wooden mullion and transom windows on the first floor and in the stairwell, and a central doorway within a stone arched surround, likely re-sited. The north front has a three-light leaded oak mullion window to the right of the stack, further paired leaded casements on the ground floor, and an overhanging 20th-century passage extension to the first floor. A modern door is situated in the angle to the right. The cottage, with two storeys and two bays, features 3-light oak mullion windows with some leaded panes in the lower left and upper right-hand bays.
The interior of the center part, initially open to the roof, contains a single cruck to the north, with a corbel moulding just below the first floor and an upper section supported on an arched brace with a simply carved circular boss at the apex of the first-floor room. This area was partitioned and divided into two storeys in the 16th century, incorporating Tudor arches to doorways and a stone fireplace, moulded beams, and stop-chamfered joists. The cross wing has collar and tie beam trusses with arched braces, possibly once open to the first-floor room. A ground-floor room in the south of the cross wing also has similar beams and joists.
