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

This is a range of farm buildings including a corn barn, granary, threshing room, and cowhouse, likely dating from the 18th century with later additions. The complex is located at Llwydiarth Esgob Farm and possesses group value from its contribution to the farmstead's historical significance.

The range is composed of a central corn barn with an advanced wing to the left, built at a lower level as a lofted cowhouse, and a rear, right-hand wing serving as a mechanised threshing room with a granary above. A raised walkway runs along the front wall of the barn, with stone steps on the right side providing access. The walls are constructed of random rubble masonry, with the corn barn and forward wing roofed with small, irregular slates, while the rear wing has regular slates. Tiled copings and ridge tiles are present throughout, and two skylights are visible on the barn/granary roof.

The corn barn itself is in two sections. The left section represents the original three-bay barn, with a two-bay addition to the right which incorporates a granary above. Each section features a narrow, split boarded door with stone voussoir heads, and corresponding doors in the rear wall. Between the doors is a tall ventilation slit, followed by two narrower slits to the right. The rear elevation mirrors this detailing; however, the ventilation slit to the left of the main section's door has been enlarged to create a two-pane window. The granary portion is partially obscured by the later threshing room.

The forward cowhouse wing is built at a lower level and contains two narrow, split, boarded doors set closely together, with arched brick heads. A two-pane window with a stone lintel is positioned to the left. The granary above is accessed by a low, boarded door on the far right, approached by three stone steps from the raised walkway. A blocked opening sits to the left of the door, and a small agricultural-pattern window, complete with a ‘hit and miss’ ventilator (with an internal sliding partition to control airflow), is located to the far left under the eaves. The granary has two matching windows on the rear elevation.

The rear threshing room and granary wing has a pitched roof, and a stone staircase is built against the gable wall, leading to the granary door. There are opposed doors at the eastern end, connecting to the corn barn, and opposed granary windows towards the centre. The return (north) side has a window to the right of the door. At the angle between the threshing room and the corn barn, there was formerly a horse works powering the machinery. The site of the yard was located to the west.

Inside the corn barn, the left-hand three-bay section has two collared trusses. The two-bay addition to the right has a strutted kingpost roof truss. The lofted cowhouse is divided internally by a stone wall, creating two bays on either side, each with collared trusses.
