Carnsew Farmhouse Including Adjoining Front Garden Wall

Carnsew Farmhouse, which includes an adjoining front garden wall, is a farmhouse that dates from the 17th century or possibly earlier, with extensions made in the 19th century and some rebuilding in the 20th century. The building is constructed from granite ashlar and granite rubble, featuring granite dressings, while the left-hand wall of the rear kitchen wing is finished in stucco. It has a steep concrete tile roof and large granite rubble stacks over the original gable ends, as well as a lateral stack on the right-hand wall of the rear wing.

The farmhouse has an irregular plan, originally consisting of a two-room layout with a contemporary or 17th-century kitchen wing positioned at right angles behind the right-hand room. A single-storey service range was added in the 19th century, running parallel to the back of the house. In the 1960s, a 17th-century or earlier range on the right side was demolished, and a new house was built on a similar site. The rear wall and left-hand gable end of the farmhouse were partly rebuilt, likely in the 18th century.

The exterior features two storeys and a nearly symmetrical three-window front facing southeast, with a doorway slightly to the left of the center. The 17th-century (or possibly older) doorway has a four-centred arch and is chamfered, set within a 17th-century open porch that includes settles and chamfered granite piers. To the left of the doorway is a three-light chamfered mullioned window. The other openings are likely from the 18th century or are 17th-century windows that have been altered, except for the right side, which has been partly rebuilt in the 20th century. Large oak brackets under the eaves may date back to the original nine-bay roof structure.

The adjoining front garden wall, located at the left-hand corner, is made of old rubble with dressed granite copings. Inside, the farmhouse has a simple interior that remains largely unaltered since the 18th century, featuring granite flags on most of the ground floor. The right-hand room has probably original chamfered hardwood beams, although the stops are not visible. There is an 18th-century straight flight stair, three 18th-century two-panel doors, an 18th-century chimney-piece in the left-hand chamber, and an 18th-century roof structure with pegged tie beams and apices.
