Former House and Adjoining Piggery at Approximately 25 Metres East of Boscarn Old Farmhouse

This is a former house and adjoining piggery located approximately 25 meters east of Boscarn Old Farmhouse. The house dates from the 18th century, while the piggery was built in the mid to late 19th century. The structure features some granite ashlar, with the majority being granite rubble and granite dressings. The roofs are covered with grouted scantle slate, except for the right-hand end of the piggery, which has been replaced with corrugated asbestos. The building has gable ends, with the right-hand (south-west) gable end featuring coping stones integrated into the dressed gable masonry. There is an external ashlar stack at the opposite end, although the chimney has been removed, and a brick chimney stump is visible at the front of the outbuilding.

The overall layout is L-shaped, with a two-room-plan house that has been converted into a one-room space. In front of the left-hand side, there is a single-storey range that includes a stable, piggery, and swill kitchen. The front and rear walls of the house were partly rebuilt in the 19th century, and the current front may have originally been the rear.

The exterior of the house is two stories high, with a single-storey farm building extending at right angles from the left-hand side. The house has an irregular north-west front featuring a central doorway with a window above, another doorway towards the left, and a small window in the former waggon doorway on the right. There is a lean-to structure in front of the right-hand side and another lean-to at the right-hand end. The rear of the house has a central doorway, a window to the right of the doorway, and a small window above. The outbuilding has a regular south-west front with two low doorways for pigs in the middle, a doorway at the far left leading to the swill kitchen with a small window on its right, and a similar front for the stable on the right.

Inside, the house features a large fireplace on the left and a fireplace for the former chambers, with 19th-century roof structures.
