Tregonna House

Tregonna House is a farmhouse, now a private house, dating to around the 18th century, substantially remodelled in the early 19th century. It is constructed of stone rubble, with some slate hanging, and has a scantle slate roof with hipped ends to the front range and an asbestos slate roof to the rear. Brick chimney shafts are located at the ends of the building.

The original layout is uncertain, as evidence suggests the house was significantly different in shape before the early 19th-century remodelling. The early 19th-century plan largely survives, consisting of a front range with a two-room layout and central passage, heated by end stacks, and a single-room service wing to the rear right.

The front elevation is symmetrical, with three windows on each floor. It features complete early 19th-century 12-pane hornless sash windows. A central panelled door, set within a matching doorcase, is flanked by two sash windows with dressed stone flat arches, and there are three similar sashes above. The service range to the rear right has windows with four-centred arched openings.

Inside, the left-hand room has an early 19th-century plaster cornice displaying intertwined floral motifs, as well as a 19th-century Delabole slate chimney-piece. The partition between the right-hand room and the passage has been removed. There is 19th-century joinery in the kitchen at the rear right.
