Description
Trevarthian Farmhouse is a granite and elvan rubble farmhouse, initially built in the 17th century and subsequently remodelled in the 18th, 19th, and 20th centuries. It has a main L-shaped range with a smaller stair outshut, creating an overall irregular U-shaped plan. Originally, the front likely featured two large reception rooms with a central cross passage leading to a stair hall. Behind the left-hand room was a late 17th-century kitchen wing, and a later 18th-century dairy wing returned from the rear right of the kitchen, running parallel to the main range. In the 19th century, the kitchen wing was divided into two rooms, a doorway and extra windows were inserted into the left-hand wall, the roof of the dairy wing was raised, and a lean-to was added to the right-hand gable end. The south-south-east front, with three windows, was partly rebuilt in the 19th century and likely presented a symmetrical five-window facade with a central doorway in the 18th century. The current doorway, located towards the left, has a circa early 19th-century six-panel door with later glazed top panels and overlight. The ground floor windows are mostly circa early 19th-century 12-pane hornless sashes - except copy replacements. Straight joints on the left-hand side wall and irregular joints around the original doorway position and flanking the right-hand windows suggest the history of earlier alterations. A circa 19th-century four-panel door with a four-pane overlight and horned sashes are also present on the left-hand side. The interior was not inspected, but the right-hand room contains fielded panelling and an elaborate 18th-century style fireplace with paired columns and a carved frieze depicting a hunting scene.
