Sarn Farmhouse

Sarn Farmhouse is a two-storey building with an attic, featuring a three-window front. The house includes an integral lean-to on the east side and a gabled wing at the rear. It is constructed of random rubble and has a renewed slate roof. There are two end stacks, with the left stack made of stone and the right stack of blue brick. The front elevation has three renewed dormers, each with 2-light casements. The house is double-fronted, faced with unusually large blocks of stone. On the first floor, there are three equally spaced 9-pane windows with segmental heads. The ground floor mirrors this arrangement, with windows on either side of a centrally placed door that has a timber lintel. The door is planked and features a glazed panel.

The lean-to on the left has a renewed window under a timber lintel on the return elevation in the lower storey, along with a recently inserted window under the wall plate. The rear gabled wing has an outshut with a catslide roof and an end stack made of stone. The lateral wall on the west side is roughcast and has three iron frame windows that were inserted in the mid-20th century. A shallow two-storey outshut was added to the rear of the main range during the same period. There is also a single-storey gabled projection on the west side, made of rubble stone, featuring a planked door on the south side and a blocked doorway on the north side.

The main range has a two-unit plan with a central stair hall. The stair has two flights, with some treads replaced. The partition between the hall and the room to the right has a light timber frame. The room to the left contains a large fireplace, which has a replaced bressumer and a 19th-century brick range, along with two chamfered spine beams and exposed joists. A door beside the fireplace leads to a former pantry that has a cobbled floor. The rear gabled wing features a fireplace with random rubble jambs, a chamfered bressumer, and a bread oven with a cast iron door made by the Coalbrookdale Company. All original internal doorways have ledged and battened doors.
