North-east Barn at Mostyn Hall Farm with adjoining stable range and flanking wall

Large barn of random rubble under slate roof with coped gables. A long range with near-central chamfered-arched high double doorways aligned in each elevation. Elevation to yard has 3 high-set segmental-headed windows to L of this central doorway, and 2 tiers of blocked vents. One similar window to R of doorways, and vents as before. Altered openings near angle with SE range. On the garden elevation, the central doorway is flanked by high-set vents with brickwork blocking.

Adjoining the NE corner of the barn to the rear, a length of wall links it with Porth Mawr: rubble stone with roll-moulded ashlar chevron copings. Adjoining the NW gable of the barn, is a late C19 low single storeyed range: this comprises 5 stables in blue brick with ashlar dressings, each expressed as a small advanced bay, with boarded doorway and small window beneath coped gable.

Adapted for use as a grain store with drying equipment, but otherwise an uninterrupted space of 7 bays with queen-post trusses.
