Treguff Farmhouse

Treguff Farmhouse is a gentry farmhouse of architectural importance, constructed primarily of local limestone with sandstone dressings including quoins, though these are now overpainted. The building is mostly two-storeyed with an attic, but the western wing rises to three storeys. It features a whitewashed exterior, a slate roof (replacing earlier stone tiles), and large stone chimney stacks, some of which have been rebuilt. The western wing is distinguished by battered walls.

The main front faces south and comprises five bays with modern render. At the time of inspection in May 1995, the fenestration was undergoing replacement with sunk-chamfered stone surrounds, stone mullion and transomed windows, and surviving hoodmoulds above. The building is particularly distinctive for its off-centre, two-storey porch with half-glazed doors and a painted-over sundial set into the gable above a broad Tudor label. The inner doorway features broach stops. The rear elevation to the north shows re-capped lateral chimneybreasts of the hall and parlour with deep lean-tos. The western downhill gable end has a further chimney breast, and a nineteenth-century mono-pitch roof extension to the south side of this end creates a small courtyard by the back door.

The interior follows a three-unit plan form comprising a hall flanked by both a kitchen and a parlour, with wings extending to the north and south of the kitchen. The hall retains its fireplace lintel with hour glass stops, and a four-centred arch dressed stone doorway with diagonal stops leads to the staircase. The south wall preserves an early window seat. A deeply chamfered ceiling beam with broach stops and reeded plaster border decoration survives. The hall floor is constructed of lime and aggregate, known as an "ox-blood" floor on account of its red colour. The adjoining parlour to the east is stepped up and was substantially altered in the nineteenth century, with a repositioned ceiling beam and an alcove in the north wall probably representing a former fireplace. A blocked doorway may indicate a former mural stair.

One of the finest features is the corbelled or cross slab roofed staircase rising beside the hall fireplace, with stone steps now boarded. At the top is a two-light sunk-chamfered window. Access from here leads to the chamber over the hall, which now contains a nineteenth-century passage along the north side and a plaster ceiling with stop-chamfered beams. The window reveals display unusual plaster decoration featuring a Tudor rose beneath a fleur-de-lis and the "ER" monogram. The chamber over the parlour has been altered similarly to the parlour itself, with the chimney removed to create an alcove. The chamber over the kitchen was narrowed by a nineteenth-century timber staircase insertion but retains broach stop chamfered beams. At the southwest corner is an opening into a long narrow space known as the "wig-cupboard", though it more likely originated as a latrine. The chamber in the north wing displays similar plaster decoration to that in the room over the hall, but here placed on the wall rather than in the window reveals. The three-storey western wing contains an upper chamber with a coved ceiling and, above the fireplace, another example of the "ER" monogrammed plaster decoration. The original roof structure is retained, with collared trusses and two rows of purlins.
