Nearby, a wooden hopper still sits over its bedstone, and a secondary shaft with a row of pulley wheels hangs from the ceiling above a Harrison McGregor metal grinder on the ground floor. The machinery was never stripped out. It was simply left, and it has been slowly surrendering to time ever since.

The Walton family are credited locally with building the mill around 1750, and the same family later constructed a separate oat mill nearby. The corn mill that survives today is a rectangular structure running roughly 24 metres north to south and 6 metres east to west, though the building grew more complex over time. A two-storey grain-drying kiln, a structure used to reduce moisture in harvested grain before milling, was added to the north end, and a residential block was attached to the east, giving the whole thing a T-shaped ground plan. The original waterwheel was at some point replaced by a small inward-flowing turbine fitted into the old wheel-pit, fed by a narrow pipe from a mill pond to the west, now dry. The turbine drove two pairs of millstones on the first floor through a belt and pulley system, while a secondary line shaft distributed power further to additional grinding equipment below. The grain-drying kiln is particularly well preserved in detail: a brick-lined furnace on the ground floor, stone slab flooring above resting on wooden beams, and ceramic drying tiles still in place. By 1842 the mill was significant enough to be named on the Ordnance Survey six-inch map of the area, which gives some indication of its standing in the local agricultural economy.

Two millstones remain on site, one propped against the first-floor wall and another lying in the yard to the south-west. The eastern spindle assembly, running from the ground floor up to the first-floor bedstone, is still in position, complete with its wooden hopper and long shoe, the angled trough that fed grain steadily down into the eye of the stone. The western assembly is gone. Weighing scales, enclosed wooden grain elevators, and a separator are also present, making this one of the more complete survivals of its kind in mid Cork.
