Tregonjohn Farmhouse

Tregonjohn Farmhouse is a farmhouse dating from the early to mid-19th century, with later 19th-century additions and 20th-century alterations. It is constructed of slatestone rubble with granite dressings and quoins, and has a slurried scantle slate roof with ridge tiles and gable ends. A brick stack rises from the gable.

The original plan comprised a two-room layout with a central entrance, and principal rooms of equal size flanking it, each heated by a gable-end stack. A large, two-storey service wing was added to the rear right, likely in the mid to late 19th century. At the same time, a single-storey wash house was added to the left end, heated by a side stack. A single-storey, unheated outshut, probably a dairy, was also constructed to the rear centre and left of the main range during the 19th century.

The front elevation is symmetrical with four windows, two storeys high. The first floor has four 19th-century sixteen-pane sashes with cambered granite arches and keystones. The ground floor features an early 20th-century brick and wood glazed porch with a half-glazed door, and matching twenty-pane sashes to the right and left, also with cambered granite arches and keystones. A single-storey wash house is attached to the left side, with a 20th-century two-light six-pane casement in the gable end. The right side of the farmhouse has a blind gable.

The two-storey rear wing is slightly set back and has three windows on each floor, all 20th-century insertions into original openings with granite lintels. A 19th-century porch with plain columns supporting a flat hood is located on the ground floor, second from the left, with a 20th-century half-glazed door and overlight behind. On the rear gable end, an external stack is present, along with an attached single-storey 19th-century lean-to with a two-light three-pane casement and a 20th-century porch. An integral outshut is located on the left (inner) side of the wing, with a stack rising from the slope and a 19th-century eight-pane sash to the side. A 19th-century sixteen-pane sash is present on the first floor of the wing’s inner side. The rear of the main range features a single-storey outshut with a 20th-century nine-pane light and a three-light casement. A two-light casement and nine-pane sash are located on the first floor, along with a small single-storey addition with a nine-pane sash.
