Trethinna Farmhouse

Farmhouse. It likely dates from the 17th century and was extended in the 18th century. The farmhouse is constructed of rendered stone rubble and cob, with rag slate roofs featuring gable ends. The cross wing on the left has a higher roof with a gable end facing forward. Several early crested ridge tiles are still present. An ashlar granite end stack with a moulded cap is on the right, and a stone rubble axial stack is located near the centre. There are also truncated stone rubble side lateral stacks to the cross wing on the left and to the kitchen wing on the rear.

The original layout was a main range with three rooms and a through passage, with the entrance positioned to the right of the centre. The lower end is on the right and heated by an end stack. Above the passage, on the left, is a hall heated by an axial stack backing onto the passage and cross wing. A cross wing, possibly a parlour wing, extends further to the left and was originally heated by a side lateral stack. A single-room unheated wing continues to the front of the cross wing, its purpose remaining uncertain. A kitchen wing from around the 18th century is located at the rear of the hall and was originally heated by a side lateral stack. Circa 18th century outshut extensions have been added to the rear of the cross wing, and to the rear of the passage and lower end. This outshut contains a stair serving the rear of the lower end.

The front facade is asymmetrical, with three windows. The entrance, positioned to the right of the centre, features a 20th-century part-glazed door. There is a 19th-century three-light casement window to the right, illuminating the lower end, and an early 18th-century four-light casement window to the left, with heavy glazing bars and early glass, illuminating the hall. Three 19th-century four-over-eight pane sash windows are on the first floor. The unheated wing to the front left contains a plank door and a two-light casement window on the right-hand side, and two small slit openings on both the ground and first floors to the left, which may have originally lit a stair.

During a recent inspection, only the kitchen wing and passage were examined. Earlier features have been covered over, the fireplace blocked, and the ceiling boarded. The owner reports that earlier features within the house remain intact, despite being covered.
