Trethiggey Farmhouse

Farmhouse, circa 1830-40, said to have been built for Sir Thomas Dyke Acland. It is constructed of brown elvan ashlar to the front, with stone rubble to the rear. The building has a hipped slate roof with ashlar stacks to the sides, featuring cornices and deep bracketed eaves. The plan is double depth, with a central entrance and principal rooms to the front left and right, a kitchen to the rear left, service rooms to the rear right, and a stair to the rear centre. At the rear, the service rooms form two shallow wings.

The exterior is symmetrical, with a three-window front, and features original 16-pane sashes with voussoirs and keystones. A panelled double door with a four-centred arched margin glazed fanlight sits within an elliptical recessed archway. The building includes a plinth, a band course, and rusticated quoins. A blind painted sash is located at ground and first floor to the left and at first floor to the right on the right side, with a sash at ground floor right. A 16-pane sash sits to the centre at ground and first floor. The left side is blind, with a plate-glass sash at first floor to the right. The rear features two shallow wings, a central round-arched stair light with radiating glazing bars. The wing to the left has a door at ground floor and a 16-pane sash at first floor. The wing to the right has a door, a 16-pane sash, and another 16-pane sash at first floor. A small single-storey outhouse is attached to the right.

Inside, the front entrance hall has a plaster cornice with a central rosette and hexagonal paving in brown elvan. A dog-leg stair features a wreathed handrail, stick balusters, and a scrolled string. The front right room has a wooden chimneypiece and a plaster cornice. Painted imitation wood graining of circa 1950, but of high quality, is present on the ground floor doors and joinery. The kitchen to the rear left contains a 20th-century range in the fireplace, a 19th-century mantel and gun rack, and a settle by the rear window. Servants' bells and a service stair are boxed in to the rear left. The dairy and larder to the rear right have slate paving, and a wooden bacon rack is preserved in the house. This is a high-quality early 19th-century farmhouse retaining its original plan and internal features.
