Agricultural range at Ty Hen Newydd

This is an agricultural range, built symmetrically to a semi-circular ground plan, with straight sections. It likely dates to the 18th century. The central portion features a former three-bay corn barn with a loft, flanked by single-storey wings, and a one-bay cartshed at each end. The range is constructed from random stone walling, with shallow stone arches over the openings, featuring dressed stone voussoirs. Slate roofs cover the structure, with a tiled ridge; the end cart bays have hipped roofs, while the central lofted barn is gabled. Modern metal-framed casement windows are present, alongside some boarded doors. The wing to the left has openings arranged as DWDWWD where the windows are all blocked doors. The wing is punctuated by tall ventilation slits, some of which have been partly infilled. Single-pane skylights are visible on the front pitch. The rear elevation includes a blocked door to the right and a boarded door to the left.

The central corn barn has a three-quarter width door to the left, flanked by tall ventilation slits, most of which are now infilled. To the right is an external stone staircase leading to a boarded granary door under the eaves, with a granary window to the left. A narrow door is situated at the right end of the higher, central barn range. The corn barn was converted into a stable for working horses in the late 19th or early 20th century, following the installation of threshing machinery to the right side of the range. A brick lean-to was added to the inner side of the range in the late 19th or early 20th century to house an engine, probably oil-powered. A narrow, brick-lined slit in the wall allowed a drive belt to pass into the range, connecting to driveshafts for threshing, chaffing, and chopping machinery.

The cart bays at either end are separated from the main wings by stone walls, while the remainder of the wings are interconnected, although the corn barn is only accessible from the yard. The roof structure comprises sawn and bolted collared trusses, with a single kingpost and struts in each wing. The wing to the right contains a driveshaft with belt wheels attached to one wall, formerly driven by the engine in the brick lean-to. Surviving timber posts indicate the previous use of the central corn barn as stables for working horses in the late 19th or early 20th century.
