The rear of the granary has a doorway under a segmental head with voussoirs, offset to the L, and a boarded window to the loft with timber lintel and reveals partially in brick. Adjoining the W end is a small lean-to, possibly for a cart, open to the front with timber fascia, and masonry to the rear. Further lean-to to E end with open front and corrugated roof. The apex of the E gable of the barn contains a ventilation strip.

Listed as a well preserved threshing barn of the late C18 - early C19, a feature of Welsh agriculture before the mechanisation of farming. Now a scarce building type in this region.
