Piggery and Sheep Shed, Leighton Farm

Consisting of 2 circular sheds both of which are open in the centre; the W shed was a sheep house, the E shed was a piggery. These are joined by a long link range which housed sheep on the N side, facing the fields, and probably cattle on the S side facing the 2 stockyards. The link range has a short S wing attached to the mill, which also housed cattle while its attic was probably used for fodder storage. Single storey and of brick with vent ridges and slate roofs. The link range has an aisled cross-gable on its N side forming an impressive facade. The cross-gable has a coped gable on moulded kneelers. In the gable are 2x round-headed windows (partly louvred) and below are 4 similar windows. The basement of the cross-gable has 4 tunnel-vaulted bays to L of which is a stairway leading to an open walkway on the N side of the link. The walkway has a high brick parapet wall and is built on a rubble plinth with a single large round-headed opening flanked each side by 2 lunettes, leading to 5 vaulted cells. To R of the cross-gable is a shorter plinth and parapet wall.

The W sheep house has some louvres in the vent ridge but is otherwise boarded or glazed. C20 windows and doors under concrete lintels are inserted in its outer wall. Its inner wall has drains at the internal floor level above a deep sump in which there are 8 radiating tunnels with round-headed openings. Around the W and N sides of the sheep house is a coped brick wall. The E piggery is built on a random rubble plinth. It has some louvres in its vent ridge, which is otherwise boarded, and has inserted doorways in its outer wall. The piggery also has a single-storey E wing, probably built as a cowhouse, with 6 infilled arched openings in the S wall and large sliding wooden doors in the E gable.

The S wing of the link range has louvres in its vent ridge and C20 openings.

The circular ranges have concrete floors.
