Tremagenna Farmhouse

Tremagenna Farmhouse, now a private house, dates to approximately the late 16th or early 17th century, with extensions added in the early 19th century. The construction is of stone rubble, with some parts rendered on the left side. The roof is covered in rag slate, featuring gable ends, with a similar roof to a parallel range at the rear. Stone rubble end stacks are present on the front range, while brick end stacks are on the rear range.

The original layout is uncertain, potentially originating as a two- or three-room plan with either a cross or through passage. The right-hand room, illuminated by a three-light mullion window, has a stack with a cloam oven. The left-hand room features a smaller fireplace in the end wall, with an unmoulded granite lintel. A blocked door at the rear suggests a possible central passage position, and the original front entrance may have been opposite. The left-hand room may have been originally larger or divided into two, and the central room could have been an unheated service room or a hall, whose stack was subsequently removed. In the early 19th century, a two-room range with a central entrance was added to the rear, leading to a reorientation and remodelling of the house. The two later front rooms, with end stacks, became reception rooms, while the earlier ground-floor rooms at the rear were utilized as service areas.

The circa 17th-century range presents an asymmetrical two-window facade, alongside a single-story, 20th-century stone rubble extension with a slate roof and asymmetrical gable end to the left. This extension has a 20th-century two-light casement, while the right side features a circa late 16th or early 17th-century three-light mullion window with hollow chamfered mullions and a hood mould. A 20th-century slate-hung porch is present. The first floor has two 20th-century two-light casements. The early 19th-century range has a three-window front with a central 20th-century door, two 2-light casements, and three four-pane sash windows above. Granite lintels are found over the ground-floor openings and the 20th-century extension on the left.

Inside the circa 17th-century range, a large granite fireplace is heated by the right-hand stack, featuring chamfered lintels and jambs, alongside a cloam oven. A circa 18th-century granite fireplace, heated by the left-hand stack with an unmoulded lintel, is also present. Ceiling beams in the right-hand room were replaced in the 20th century.
