Barn at Thornage Hall Farm C60m South West of Thornage Hall

The barn at Thornage Hall Farm, located approximately 60 meters southwest of Thornage Hall, is a range of barns dating from the 17th century, with additions from the 18th century dated 1718 and 1727. The structure is built of brick and flint and features a continuous pantile roof, extending about 80 meters in length and aligned north-south.

The barn consists of four distinct parts. The northernmost section has a brick gable in Flemish garden wall bond over a flint base, with a stone plaque inscribed "JA/I715," referring to Jacob Astley (1660-1729). The east wall is also in Flemish bond and has a dentil cornice, with openings featuring cambered arches. Inside, there is a 19th-century king post roof, with storage space on the right that has a tiled floor and a cow shed on the left with a pebble flint floor and a central drain. Some posts and rings remain from its original use.

The north central barn, now used for grain storage, is made of red brick in Flemish garden wall bond and has a castellated dentil cornice. It features a large central door flanked by four honeycombed vents under cambered arches, with a new door cut into one of the right-side vents.

The south central barn, constructed from 17th-century pebble flint, has an oversailing cornice and a large central door, with two bays on each side that include semicircular-headed honeycombed vents on both the ground and loft floors in the back bay. This section contains loose boxes with wooden troughs. The external south gable, now internal, is made of coursed flint and features decorative brickwork lozenges on a brick-capped flint plinth.

The southern barn is built of coursed flint and consists of one bay with a large opening. Its south gable is raised with brick above the eaves level in Flemish garden wall bond and includes a honeycombed opening, along with some tumbled brickwork. A stone plaque inscribed "JA 1727" is also present. This barn forms a group with Thornage Hall, the dovecote, and the lofted cartshed.
