Cotna House

Cotna House is a house dating from the early 19th century, with later 19th-century additions and some subsequent alterations. It is constructed of painted stone rubble with dressings of Pentewan stone, and has a hipped slate roof with lead rolls to the ridge and hips, as well as deep eaves. The building features axial stacks and a rear-right stack with brick shafts.

The house has a double-depth plan, with a central entrance and principal rooms to the front left and right. A garden front is located on the right side, with a further principal room to the rear right. A stair hall is positioned to the rear centre, and a kitchen to the rear left. In the later 19th century, a two-room plan wing was added to the left end, and a single-storey addition was built to the rear left as a service room.

The symmetrical three-window front has two storeys on a plinth. All windows are 19th-century 12-pane sashes with flat brick arches. A central granite Doric portico features a cornice and contains inner double, half-glazed 19th-century doors with a fanlight incorporating radial glazing bars. To the right end are two 19th-century 12-pane sashes at ground and first floors. A 19th-century 12-pane sash is at ground floor to the right of the left end, set back behind a later 19th-century two-storey addition, which has a late 19th-century 4-pane sash at ground and first floors. The left end of this wing features a 20th-century half-glazed door and a late 19th-century 4-pane sash at ground and first floors. The rear of the main house showcases a central 15-pane sash with margin glazing, set within a round arch with radial glazing bars, illuminating the stairwell. First-floor windows to the rear include a late 19th-century 4-pane sash to the right and a late 19th-century 8-pane sash to the left at ground floor. A 20th-century half-glazed door and a 19th-century 12-pane sash are to the rear right, with a matching 12-pane sash at first floor. A single-storey porch addition is present to the rear, incorporating a 19th-century 16-pane sash on its inner side and a 20th-century half-glazed door and sash at ground and first floor.

The entrance hall contains panelled double doors to the right and left. The principal rooms to the front have marble chimney-pieces and panelled window shutters. An open-well stair features stick balusters and a wreathed handrail. A large 19th-century fireplace with mantel is a feature of the kitchen.
