Description
Trevenys is a small house, likely built in the 18th century and extended in the 20th century. It features painted rubble walls and timber lintels above the openings, topped by a steep thatched roof. There is a brick chimney over a 20th-century rebuilt external stack at the right-hand end. The original house has a two-room plan, probably with a lobby entrance between the rooms. The right-hand room is likely the original kitchen or living room, which has a probable stair or pantry projection at the rear. The exterior is two storeys high, with the original house displaying a nearly symmetrical two-window south front and a doorway that is central to the fenestration. The old door has two vertical panels, while the 20th-century windows are 12-pane, two-light casements in the original openings. The interior has not been inspected.
