Sluice And Mill Lade, Longniddry Farm, Longniddry

The Stable Range at Longniddry Farm is a large agricultural complex built in the late 18th century, with mid-19th century additions. It features an E-plan layout that includes a mill and sluice at the center, with a farmhouse, stables, cartshed, and granary to the west, and cattle courts to the east. The building is constructed of random rubble with droved or stugged ashlar dressings.

The stables are a single-storey range aligned north-south, featuring doorways with windows to the left, some of which have been enlarged and fitted with wooden sliding doors.

The cartshed and granary is a two-storey, six-bay structure that stands free. It has five segmental arches at the ground level and a door to the outer right. The first floor has six openings, including two doorways at the center flanked by two windows, one of which is half-glazed and louvred. A stone forestair leads to the first floor at the south gable, breaking the eaves of the piend roof.

The mill, threshing barn, and granary date from the late 18th century, with additions from the 1850s. The mill features an overshot waterwheel, circa 1850, housed below ground level in a two-storey building, with a doorway on the south side that has an inscribed lintel dated 1850. The threshing barn is located to the south, with a two-storey range to the east that includes a granary on the first floor. Both the mill and threshing barn are covered with grey slates.

The sluice and mill lade enter the rubble-walled garden to the south, flowing over a sluice and under a segmentally arched bridge that carries the roadway.

To the east of the mill are the cattle courts, which are accessed through a depressed arch-gabled pend. There are four piend-roofed cattle courts to the west, culminating in a gabled range with low interconnecting arches, cast-iron columns, stone feeding troughs, and timber hay-hecks. The roofs are finished with red pantiles, with some areas covered in corrugated iron, and the skews are coped with ashlar.
