Norton Mill is a two-storey, grey rubblestone-built combined corn mill and mill house under a continuous pitched slate roof, and dating from early or mid-nineteenth century. Both parts have been incorporated into a dwelling conversion, with a modern slated lean-to and some weatherboarding on the north side. The mill had an overshot waterwheel 11ft (3.35m) in diameter with six wooden spokes on an oak axle, and fed from a cast iron sluice box above. There were two pairs of stones. The mill was working in 1940, but had ceased by 1951 (information from Miss E M Gardener).
