Trethingey Farmhouse, Front Garden Walls, Gate Piers and Gate

Trethingey Farmhouse, along with its front garden walls, gate piers, and gate, dates from the early to mid-19th century. The building is constructed from granite rubble with granite dressings and features a hipped roof made of grouted scantle slate, which has projecting eaves. Brick chimneys are located on the side walls, with the rear right-hand chimney positioned over an external rubble stack. The farmhouse has cast-iron ogee gutters.

The layout consists of a double depth plan, with a wider kitchen and living room on the right and a parlour on the left, flanking an entrance hall that leads to a stair hall situated between rear service rooms, likely a kitchen on the right and a dairy or pantry on the left. There is a later 19th-century single-storey service wing at right angles to the rear, positioned at both the far left and right. An old lean-to conservatory is located on the right-hand side of the house.

The exterior is two storeys high and features a nearly symmetrical three-window south front, with a doorway and a window above it, slightly to the left of the center. The original four-panel door has later glazed top panels and an overlight. The original 12-pane hornless sash windows are present at both the front and rear.

The interior has not been inspected but is likely to retain its original carpentry and joinery. The front garden is roughly rectangular, bordered by a granite rubble wall on its right-hand side, with an entrance at the rounded front right-hand corner. This entrance features granite monolithic round-headed piers and an original 19th-century wrought iron gate with cross-braced and scrolled decoration.
