Description

Jasper Farmhouse is a farmhouse that has been converted into a house. It dates from the late 17th century, with alterations and additions made in the 19th and 20th centuries. The building is constructed of painted stone rubble and features an asbestos slate roof with ridge tiles and gable ends. There are gable end stacks, with a painted rubble shaft on the right and a slate-hung shaft on the left, both topped with a cornice and shaped top. The left gable end is slate-hung. The farmhouse has a two-room plan with a central entrance leading to a passage, and each room is heated by a gable end stack. There is a later rear service wing of one-room plan, likely from the 19th century, located at the rear right.

The exterior is two storeys high with an irregular three-window range, all featuring 20th-century casement windows. The first floor has a three-light casement window on both the right and left, with a half-glazed door and a single light window to the right. There is also a 20th-century rooflight on the left. The left side of the building has a single-storey rubble lean-to, while the right side includes an external stack and a first-floor string course. The rear features a gabled wing that is two storeys tall, with a chamfered end wall and 20th-century windows.

Inside, the room on the left has a granite fireplace with a flat chamfered lintel and a cupboard recess in the rear wall. The room on the right has cross beams with chamfer and step stop, along with a fireplace that has a timber lintel. The roof trusses include chamfered principals.
