Threshing Barn and Granary, Leighton Farm

Consisting of a Threshing Barn with Granary on N side above the W and E ranges of Stockyards I and II respectively. The Granary extends N over the farm road to the Mill, where it also has an E wing with axis at right angles to the main range of the Granary, and which has an outshut attached to the Tank House. Of brick with slate roofs and with coped gables on moulded kneelers.

The Threshing Barn has stepped diagonal buttresses. In its E and W gable ends it has a tall round-headed doorway with stone imposts, above which is a bullseye opening. The side walls have blind round-headed windows, some with breathers. On the N side is a cross-gabled bay to which the Granary was later attached. On the NE side is a small structure with swept roof open to the E, said to have contained a pit (now infilled) with access to a system of drains carrying muck from Stockyard IV to a sump in Stockyard II. (Attached on its N side is another small shed with double doors under a concrete lintel to E. Attached to SW side is modern lean-to.) The Threshing Barn has a fragment of plateway in the E entrance.

The Granary has a wide vent ridge consisting of glazed and louvred panels, and round-headed openings to Stockyards I and II. Above the farm road the E wing of the Granary has horizontal sliding boarded doors with steel lintel and threshold. An outshut at the E end has a wide round-headed doorway and boarded doors with prominent strap hinges.

The Threshing Barn is divided into 3 bays internally. The outer bays have scissor braced trusses with collar beams; the central bay, incorporating the cross-gable to N, has king posts with raking struts. At the upper floor level, reached by modern wooden steps, is a large round-headed opening to cross-gable which leads into the Granary (access to which was not possible).
