Treemills Including Barn and Shippon at Left Hand End

Treemills, including a barn and shippon at the left-hand end, is a farmhouse that may have originally been a longhouse, dating from the 17th century or earlier, with the barn and shippon added in the 18th century or early 19th century. The building is constructed of granite rubble, while the house part is rendered. It features old chimneystacks with granite thatch-weatherings on the right-hand gable and on the ridge to the left of the house part.

The house part has a central doorway, likely a 19th-century addition, which leads to a passage with a stair at the rear. To the right is the parlour and to the left is the hall. There is an outbuilding to the left of the hall, now completely walled off, which has a front door on the right-hand side. This was probably the original front door to the house, although there is no opposing door in the rear wall. The barn adjoins the outbuilding on the left, and a shippon is positioned at right angles against the front wall of the barn.

The house part has three windows, featuring 19th-century casements with glazing bars, except for a 20th-century metal window to the left of the second storey. The shippon has two ventilation slits in the front wall and three in the rear wall. Inside, the hall contains a fireplace with granite jambs and a chamfered lintel, along with an oven that has a stone-framed opening to the left. The back wall of the outbuilding is made of granite ashlar with a chamfered cornice at the top. The outbuilding has an old cobbled floor, but there is no drain or other evidence indicating it was used as a shippon. The current shippon also has an old cobbled floor, this time featuring a central drain. The outbuilding, barn, and shippon have 20th-century roof timbers. According to the owner, old deeds refer to the house as Middle Dunstone.
