Description
Knowle Farmhouse is a farmhouse dating from around the mid-17th century, with alterations made in the 20th century. The building features rendered stone rubble and cob walls, topped with a gable-ended asbestos slate roof. An attached shippon has a hipped corrugated iron roof. There is one axial rubble stack with drip-stones and a brick shaft.
Originally, the farmhouse had a three-room plan, with the two right-hand rooms heated by an axial stack that has back-to-back fireplaces. A doorway in front of the stack leads into a lobby entrance, while an unheated service room is located to the left. The shippon at the left end of the building may be integral, separated from the house by a full-height solid wall, or it could date from the 18th century. In the 20th century, the interior rooms were partitioned longitudinally towards the rear, and an outshut was added at the right-hand end.
The farmhouse is two storeys high and has an asymmetrical four-window front, with the shippon at the left end continuous with the house. Most windows are later 20th-century small-paned casements, with a single light above the door and otherwise two-light windows. The two left-hand windows are from the late 19th or early 20th century. There is a 19th-century plank door at the left end and a 20th-century plank door to the right of centre. The shippon features a door at its right end and another to the left of centre, which has a ventilation slit to its left. A small window is located between the two doors, along with a central first-floor loading hatch.
Inside, the central room has a fireplace with a chamfered wooden lintel that has straight cut stops. There is an axial chamfered beam without visible stops, but its joists are chamfered with straight cut stops. The right-hand room has a roughly chamfered axial beam and joists, while the fireplace in this room is modern. The shippon contains very heavy rough wany cross beams. The roof timbers of the house were completely replaced in the later 20th century, as it was formerly thatched. Above the shippon are rough insubstantial straight principals with lapped collars, likely from the 19th century.
