Description
House. Probably built in the early 18th century, although possibly with origins in the 17th century, and remodelled in the early 18th century (a building is shown on a 1660 map). It was converted into two cottages around the 19th century and is now again a single cottage. The house is constructed of painted rubble and cob with slate sills, wooden lintels, and a wheat reed thatched roof topped with brick chimneys at the gable ends. The plan consists of a hall to the left with a large gable-end fireplace, and a parlour to the right with a smaller gable-end fireplace; an integral outshut at the rear is located in the middle and to the left, containing a central stair and a shallow service room behind the left-hand room. It is two stories high. The south front has a slightly irregular appearance, with two windows. A roughly middle doorway has a circa early 18th-century two-panel door; a 20th-century porch extends over the left-hand window and a 20th-century door fills a former window opening slightly to the right of the doorway. A small window opening above has a 20th-century window, and a larger window opening contains a circa early 19th-century 12-pane horizontal-sliding sash with crown glass on the first floor left (the opening may have been enlarged at that date). The right-hand gable end features two pointed arched openings to the ground floor left and right, and a smaller window to the first floor right, probably inserted in the 1830s, now fitted with 20th-century windows with intersecting tracery to the ground floor. The rear has a ground and first floor window left of the outshut, which was possibly cut or enlarged around the early 19th century with a 12-pane horizontal-sliding sash to the ground floor. A circa early 18th-century 12-pane 2-light casement window to the stair has wide internally ovolo-moulded glazing bars and original crown glass. A 20th-century shingle-clad thatched dormer is slightly to the right, and a 20th-century window occupies an original opening to the ground floor right. The interior has largely remained unaltered since the early 18th century, featuring a large fireplace with a chamfered, and stopped, possibly 17th-century oak lintel; a bread oven is located behind the left-hand (south) jamb, likely inserted in the early 18th century; a fitted settle, ovolo-moulded beams, a pine muntin and plank partition, and a dog-leg stair with twist splat balusters are also present. Three two-panel doors on the first floor are possibly 17th century, or archaic early 18th century, with wide stiles, strap hinges, original latches and wooden handles. The roof structure is of 18th-century pine, with lapped pegged collars and pegged apices, lime-washed over the chamber above the hall. Some superficial 20th-century alterations have occurred, but much of the fabric from the 18th century (and possibly earlier) has been retained. Particularly notable are the stair window, the stair, and the two-panel doors.
