Smynacott Farmhouse Including Cob Garden Walls Adjoining South-East Front

Smynacott Farmhouse is a farmhouse that dates from the 16th century, with an early 17th-century extension and improvements, and underwent modernization and extension in the mid-19th century. It is constructed of plastered cob on rubble footings, with rubble stacks topped by 19th-century brick chimney shafts, and a 20th-century slate roof featuring red ridge tiles over thatch. The house has been much altered and follows a three-room-and-through-passage plan, facing southeast, with a former inner room located at the right (northeastern) end. There is an early 17th-century kitchen block at right angles to the rear of the former hall, and a 19th-century extension to the former service room at the left end. The building features projecting gable end stacks for the kitchen and inner room, as well as a front lateral stack that projects from the former hall.

The farmhouse is two storeys high and has a five-window front, with mid-19th-century and 20th-century replacement horned sashes. Most of the windows are 16-pane sashes, although two ground floor windows on the right (to the former inner room) are 12-pane sashes, and the left extension has a 12-pane fixed pane window under a segmental head. The main entrance is a 20th-century door located to the right of the hall stack, accompanied by a contemporary porch with a slate roof and glass sides. The original passage door was to the left of the stack but is now blocked by a sash window. There is a plank door at the left end leading to the extension. The gable-ended roof steps down to the extension.

The interior has largely been altered due to mid-19th-century and 20th-century modernizations, but some early features are still visible, suggesting that more may be concealed. Cob crosswalls are present at either end of the hall, which is floored with a late 16th-century to early 17th-century chamfered crossbeam with pyramid stops. A similarly finished half beam towards the lower end indicates that there may have been an earlier internal jetty at that end. The former hall-passage screen has been removed, and no early details are exposed in the inner or service rooms. The kitchen contains an early 17th-century crossbeam that is chamfered with late step stops, but all fireplaces are blocked. No early features are visible on the first floor. The mid-19th-century roof structure includes king post trusses.

On either side of the front garden, high plastered cob walls on rubble footings extend southeastwards, topped with pitched slate coping.
