Description

Lower Nash Corn Mill is a Grade II listed building consisting of a two-storey storage range that runs east to west, with a three-storey mill wing attached to the north. The structure is built from local rubble masonry and features slate roofs. The main building measures approximately 25 meters long and 7 meters wide, with a roof divided into 13 bays. Access is provided from the south side, and there is a cart entrance on the west side that includes a gap in the floor for loading from the upper level under cover. Additionally, there are two high-level loading doors in the south wall. To the east, there is another cart entrance that has been enlarged to accommodate farm machinery.

The mill wing on the north side measures about 7 meters by 5 meters and is covered by a roof with 4 bays. The water wheel is located beneath this wing, at the junction with the main building. Although no maker's name has been identified on any of the machinery, the mill equipment is largely intact but in disrepair. It includes a sluice, launder, an overshot wheel with a diameter of about 4 meters featuring rim-drive, cast-iron gearing with wrought-iron axles, and a single pair of millstones situated above a bridge-beam.
