Description
Trevarthian Farmhouse is a farmhouse dating from the 17th century, with extensions from the early and late 18th century. It is constructed from killas with granite dressings, while a lean-to is made of stone and cob, topped with slate roofs.
The original building consists of two rooms, with a lean-to added at the back that includes service rooms. A front block was added in the late 18th century, also featuring two rooms and a central through hall that connects to the earlier structure, which has been partly altered or rebuilt. The farmhouse is two storeys high, with the added elevation comprising three bays. The central entrance features a part-glazed 19th-century door, flanked by 16-paned sash windows, with four 4-pane windows on the first floor. All openings have segmental brick arches and keystones, and the roof is hipped with a stack located at the right gable.
The interior does not have any significant features. Trevarthian was an early barton in the parish of St Newlyn East and was granted a licence for a chapel in 1400.
