Trethannas Farmhouse

Trethannas Farmhouse, probably dating to the early 18th century, may incorporate elements of a 17th-century building. It is a two-room farmhouse, now used as a store. The farmhouse is constructed of granite rubble with dressed granite quoins, jambstones, sills, and lintels, roofed with scantle slate. Large dressed granite chimneys are located over each gable end. The original plan comprised a larger hall or kitchen to the left with a large fireplace, and a smaller room to the right, likely a parlour, with a smaller fireplace, connected by a passage that has since been partitioned away. The eaves were heightened in the 19th century, and a dairy was added behind the right-hand room around the same time. A rear doorway was enlarged in the 20th century. A chamfered granite fragment, possibly from the original house or an earlier structure on the site, has been reused over the doorway of a nearby outbuilding. The south front is nearly symmetrical with two window bays, a four-panel door, later glazed to the upper panels, slightly right of centre. The window openings on the left are somewhat irregularly placed, and the windows are presently boarded or missing. Internally, the floors and roof structure are from the 19th century, and the original fireplaces are partly blocked. The farmhouse appears largely unaltered since the 19th century and retains two fine original chimneys.
