Stockyard III, Leighton Farm

Stockyard III at Leighton Farm is a Grade II* listed structure consisting of a yard surrounded by a curved cow shed on the north and west sides, which leads to a hay shed at the south end, featuring an east wing. The yard is enclosed by the west range of Stockyard II on the east side. The buildings are constructed of brick with slate roofs, set on a random rubble plinth. Access to the yard is from the north side through full-height corrugated-iron doors.

The cow house is open-sided, supported by timber posts on concrete bases, although it is now partly boarded up. The hay shed at the south end features coped gables on moulded kneelers. It has two round-headed doorways with boarded doors facing the yard, while the east wing contains two similar doorways, one of which is infilled, along with an inserted full-height opening on the east side. On the west side, facing the farm road, the hay shed has a central coped gablet with a round-headed doorway above the plinth and a boarded door with weatherboarding above. There are also two blind windows with segmental heads flanking the doorway. Both the hay shed and its west wing include skylights.

Inside the yard, there is a central dividing wall of brick that continues with the north wall of the hay shed. The southern side of this wall is laid with blue bricks. The cow house and hay shed feature king-post roofs with raking struts, and the cow house is divided into bays by brick partition walls. The boarded doors in the hay shed slide on horizontal runners.
