Description
The Brewhouse and Piggeries at Plas Harri is a small rectangular vernacular brewhouse, likely built around the same time as Plas Harri, which dates to 1764. It features adjoining 19th-century piggeries. The structure is made of local rubble and has a small slate roof with a tiled ridge. The farm-facing gable has superimposed slate-slab copings, a boarded entrance with an exposed oak lintel, and to the right, a very small contemporary window with a pegged frame and boarded shutter. There is a squat chimney on the road-facing gable (east) with plain capping. On the south side, there is an entrance with a boarded stable door to the right, featuring a large projecting stone lintel, and to the left, there is another small square boarded window.
Attached to the former brewhouse on the south is a later two-bay pig-sty block made of rubble with a slated roof, where the north pitch is longer than the south. This block has two plain entrances leading to paired sties, with rubble-walled open pens in front, separated by another rubble wall. The north roof pitch includes two sections of corrugated plastic.
Inside the brewhouse, there is a single bay with a large staged end stack of inglenook type.
