Pentrusco Farmhouse and attached agricultural range.

Pentrusco Farmhouse is a 18th-century farmhouse with an attached cow house, forming an L-shaped plan. The farmhouse is constructed of whitewashed rubble stone with a hipped tile roof. The three-storey front has a central boarded door, now sheltered by an added canopy. It has three windows across the front, with a two-light window under a segmental head to the left of the door and a two-light window under a lintel to the right. The middle storey features two-light windows on each side, plus a smaller fixed landing window in the centre, all except for the right-hand window having segmental heads. The upper storey has a small casement to the right under the eaves, and a smaller casement to the left added in the 1990s. A lean-to addition to the left end of the farmhouse has a two-light casement in the lower storey and a small fixed attic window, with a boarded door and a two-light casement below the eaves on its side wall. The rear of the farmhouse includes a shallow outshut, rebuilt of rendered brick on an earlier stone plinth, with two pointed windows featuring Y-tracery and small-pane iron-frame casements. A late 20th-century projection on the left side of the house, against the right side wall and behind the farm range, conceals a narrow stair window.

The cow house is part timber-framed with weatherboarded front, a stone gable end with a lean-to (currently under reconstruction) and a corrugated iron roof. Facing the yard, it has three boarded doors and a loft opening. The rear wall is a combination of rubble stone and corrugated iron.

Inside the farmhouse, despite its symmetrical front, elements of a traditional hall plan remain. The entrance hall features a lateral fireplace with a timber lintel and a single stopped spine beam. A timber-framed partition separates the hall from a small inner room, behind which is the stair. The dog-leg staircase has plain balusters and a newel to the middle landing, but lacks balusters on the upper landing. A boarded door and stone steps provide access to a cellar beneath the stair, and the lower landing retains old floorboards. The roof structure incorporates tie beams with diagonal struts.

The cow house retains visible timber framing, king-post roof trusses with raking struts, pole joists to lofted areas, and stalls. The floors are a combination of cobbled and stone flagged surfaces.
