Trevear Farmhouse, Including Garden Walls

Trevear Farmhouse, including the adjoining garden walls, is a farmhouse dating from around 1850. The garden front and entrance gable end are made of granite ashlar, while the rest of the building is constructed from granite rubble with granite dressings. The roof is covered in scantle slate and features granite coped gable ends with moulded kneelers. Brick chimneys with pairs of diagonally-set shafts are located over the gable ends of the front range, and there is a granite ashlar chimney over the rear service wing gable.

The farmhouse has an L-shaped double depth plan with a service wing. It includes two reception rooms at the front, an axial entrance hall behind the left-hand room leading to a central stair hall, pantries behind the stair hall and the right-hand room, and a two-room service wing at the back, with the kitchen on the right. The exterior is two storeys high with unaltered elevations. The symmetrical three-window southeast garden front has no doorway, while the left-hand return gable end features a symmetrical two-window entrance front with a central doorway on the ground floor, likely a 20th-century ledged door with an original traceried overlight. All windows in the house are late 19th or 20th-century six-pane horned sashes set in their original openings. There is also a shuttered fuel hatch in the right-hand wall of the service wing.

Inside, the farmhouse is virtually unaltered, retaining original carpentry, joinery details, and plasterwork, including an open-well open-string stair, panelled doors, and plaster ceiling cornices in the reception area. The granite ashlar garden walls adjoin the rear gable end of the house and enclose a garden on the left, a courtyard garden on the right, and the area in front of the house. The walls are higher at the rear and on the right, featuring granite copings. A wide gateway with monolithic piers is located near the rear right-hand corner of the house. Trevear Farmhouse is said to be modeled after Burnewhall Farmhouse, which has a datestone from 1849.
