Trevellas Farmhouse Including Front Garden Walls

The property is a farmhouse, incorporating front garden walls, dating back to the 17th century with alterations around the late 18th century. The front elevation is constructed of granite ashlar, while the rest of the building is of granite and killas rubble. The front range has a dry Delabole slate hipped roof, while the front part of the rear wing and a lean-to to the left have grouted scantle slate roofs. There is a rendered rubble stack with a brick shaft over the left-hand wall, a probable 17th-century rubble stack with a brick shaft behind it, and a brick chimney over a 17th-century stack located between the right-hand room and the rear wing.

The original design was likely a double-depth plan, remodelled in the late 18th century from what may have been a larger, possibly U-shaped plan. It features two rooms at the front, flanking a former through passage; a back kitchen lies behind the left-hand room, incorporating an 18th-century staircase to its right (accessed from the passage), and a single-room-plan wing is set at right angles behind the right-hand room. The rear wing contains a 17th-century fireplace with two later cloam ovens. A 20th-century extension has been added over the back kitchen.

The south front has three symmetrical window bays with a central doorway. An early 20th-century porch with cusped bargeboards to its front gable features a small window above. The window openings are wide and contain tripartite sash windows, with the ground floor openings spanned by flat arches made with granite voussoirs. The windows themselves appear to be late 19th or 20th-century, horned sash windows.

Internally, the farmhouse remains largely unchanged since the 18th century. Notable features include a late 18th-century dog-leg staircase, an Adam-style chimney-piece in the right-hand room (the parlour), a moulded dado rail in the left-hand room, and six-panel doors. The 17th-century fireplace in the rear wing has an ovolo-moulded hardwood lintel. The first-floor rooms and the old, probably 18th-century roof structure were not inspected.

The large, irregularly shaped garden in front of the house is enclosed on three sides by high rubble walls. A higher wall, with scantle slate copings, runs along the right side of the house, screening the farmyard. A lower wall at the front is marked by a 17th-century terminal pier at each end, each with moulded and tapered caps topped with ball finials shaped like chess pawns.
