Outbuilding at Nantyreglwys

The outbuilding at Nantyreglwys is a 19th-century structure made of whitewashed rubble stone, topped with an asbestos-sheet roof. It is designed in an L-shape and is partly lofted. On the left side, there is a depressed-arched cart entry featuring sandstone voussoirs. The rest of the building has a single row of brick dove-holes under the eaves, which includes a slate shelf. This row is interrupted on the left by two small square loft lights, positioned above two doors. To the right of these doors, there is a third door, a small window, and an inserted door with a red brick head, while the other doors have single stone lintels. An additional short range has been added to the right at a right angle, featuring another depressed-arched cart entry on the left. This range is obscured by a whitewashed brick lean-to, which has a row of dove holes above it. The end of the building has a hipped roof and another depressed-arched cart entry with a brick arch.
