Polkinghorne Farmhouse and Adjoining Cartshed and Former Stable

Polkinghorne Farmhouse, along with its adjoining cartshed and former stable, is a Grade II listed building that likely has a core dating back to the 17th century. It was remodeled in the 18th century, early 19th century, and late 19th century. The structure is built from granite rubble with granite dressings, and the porch features slate hanging. The roofs are made of scantle slate, with brick chimneys at the gable ends, and cast-iron ogee gutters. The adjoining cartshed and stable have a hipped corrugated asbestos roof.

The farmhouse has an irregular L-shaped plan, with a parlour wing at right angles to the rear right and a single-storey cartshed and stable adjoining at right angles to the left, projecting at the front. The main range includes a shallower depth one-room plan cottage set slightly back on the left and an L-shaped three-room house on the right, which has a late 19th-century lean-to in the rear angle. The stair hall is located on the left-hand side of the rear parlour.

The exterior is two storeys high with an overall five-window front facing northwest. The cottage on the left has a slightly irregular two-window front, while the house on the right features a nearly symmetrical three-bay front. The cottage has an early 19th-century six-panel door on the left, with 16-pane hornless sashes likely from the same period on the first floor and a later six-pane hornless sash on the ground floor to the right. The house has a central doorway with a late 19th-century panelled door and late 19th-century horned sashes. A late 19th-century hipped-roofed two-storey porch is open at the ground floor and is supported by two reused 17th-century granite columns in a style resembling the Doric order. A map from 1792 indicates a porch-like projection in the left-hand window position. The stable wing on the far left has openings facing left, with the only window featuring an early 19th-century 12-pane horizontal-sliding sash.

Inside, the house retains features from around 1890 and has seen little alteration since then, although earlier features may be concealed.
