Range including cornbarn, granary, threshing room and lofted cowhouse at Llwydiarth Esgob Farm

Corn barn range; a central 2-door corn barn, with an advanced wing to L built at a lower level (a lofted cowhouse) and lofted wing to rear R (a mechanised threshing room with granary over). There is a raised walkway running along the front wall of the barn, with stone steps to the R side. Walls of random rubble masonry. Both the corn barn and forward wing are roofed with small irregular slates; the rear wing with regular slates. Tiled copings and ridge tiles throughout; 2 skylights to the barn/granary. The corn barn is built in 2 parts; the L part represents the earliest building (a 3-bay barn), with a 2-bay addition to the R (with a granary above). Each part has a narrow door, with corresponding doors in the opposite (rear) wall; split boarded doors with stone voussoir heads. Between the doors is a tall ventilation slit; to the R are two narrower slits. The rear elevation has similar detailing, although the ventilation slit to the L of the door of the main part has been enlarged to form a 2-pane window; the granary part is obscured by the added threshing room. The forward wing is a cowhouse with granary loft above. The ground floor, built at a lower level than the corn barn, has two narrow, split, boarded doors set close together in the centre of the elevation, with arched brick heads. To the L is a 2-pane window with a stone lintel. The granary above is accessed through a low boarded door to the far R, with 3 stone steps leading from the raised walkway running along the front wall of the barn. To the L of the door is a blocked opening, and to the far L an agricultural-pattern window set under the eaves; 3 small panes above a 'hit and miss' ventilator (slatted with an internal sliding partition to control air flow). The granary has 2 corresponding windows to the rear elevation. The rear threshing room and granary wing has a pitched roof, with a stone staircase built against the gable wall, leading to the granary door. Opposed doors at the E end (where the building abuts the corn barn), with opposed granary windows towards the centre of the elevation. The L return (N side) has a window to the R of the door. In the angle between the threshing room and corn barn was formerly a horse works powering the machinery. The site of the stackyard was in the area to the W.

The corn barn to the L is 3 bays, with 2 collared trusses. The addition to the R is 2 bays, lofted with a strutted kingpost roof truss. The lofted cowhouse to the front is divided internally by a stone wall, with 2 bays to either part, with collared trusses.
