The square wooden axle is broken, but it still crosses the wheel pit and connects to the gear train inside. Two bevelled gear wheels, the kind that transfer rotational force at right angles, once drove two pairs of millstones on the first floor. The slate roof and wooden floor have held, which is more than can be said for many rural mills of comparable age, and much of the gearing survives in a condition that makes the whole mechanical logic of the building legible even to a non-specialist.

By 1842, when the Ordnance Survey recorded the area on its six-inch map, the site was already working as both a corn mill and a tuck mill. A tuck mill, also called a fulling mill, was used to clean and thicken woollen cloth by beating it repeatedly in water, a process quite separate from grain milling. The fact that both functions were co-located here, with the two structures sitting only about five metres apart, suggests a practical arrangement that served a rural community with more than one kind of processing need. The corn mill itself is a gabled, three-bay, two-storey structure, roughly ten metres east to west and just under eight metres north to south. Its wheel pit, 1.6 metres wide, runs along the eastern elevation, fed by a mill race diverted from the river to the west; that race is now dry. The tuck mill to the east is smaller and roofless, measuring roughly 4.7 metres by 3.1 metres internally, with its own wheel pit along the western wall and a small bevelled gear wheel still present inside.
