Agricultural Range at Rhyd-y-Creuau

The agricultural range at Rhyd-y-Creuau is a long structure consisting of four main sections, built in the 18th century. The central barn is constructed of rubble on boulder foundations and features a medium-pitched slate roof, which was being reslated on the south pitch at the time of inspection in February 1997. The barn has a large open entrance in the third bay, with an opposing entrance on the south side that has been walled up, and it showcases exposed timber lintels. To the left of the entrance, there is a ventilation slit with a crude projecting dripstone. To the right of the entrance, the remaining three bays of the barn have been converted for stable use, maintaining a symmetrical appearance with a central segmentally-headed entrance that includes a four-pane rectangular overlight. Flanking windows have segmental heads and 20th-century wooden cross-windows.

Adjacent to the stable section on the right is a later single-storey, four-bay byre range made of rubble, topped with a corrugated asbestos roof. A later mounting block partially obscures a window opening on the left, which has fragmentary six-pane glazing. On the right, there is a boarded stable door with a similar window beyond, along with another boarded door at the far end.

East of the barn range, there is a two-storey, three-bay carthouse block that once served as a granary above. This block is also made of rubble and features a rubble gable parapet on the east side, with an old slated roof that has a pronounced undulation. It includes three segmental cart entrances with roughly-dressed voussoirs and three square windows above, which have pegged wooden frames and shutters, some of which are missing. Access to the upper entrance at the east gable end is provided by external stone steps and a rubble parapet; this entrance has a boarded door with an exposed timber lintel.

Inside the primary barn, there are pegged tie-beam and raking strut trusses, along with contemporary purlins, some of which have been strengthened or replaced. The eastern truss of the third bay is marked with the carved date 1751, which is accepted as the construction date. A later 18th-century three-quarter height rubble wall separates the three eastern bays from the converted western bays.
