The cast-iron breastshot suspension waterwheel, nearly five metres in diameter, still sits in its wheel-pit. A breastshot wheel is one where water strikes the wheel at roughly mid-height, driving it by the combined force of the water's weight and its momentum, a common configuration in Irish mills where rivers ran with moderate but reliable flow. Inscribed on the shrouding are the words "J. Steel and Sons, Vulcan Foundry, Cork", a manufacturer's mark that anchors the machinery to a specific Cork ironworks and gives the site an almost documentary quality amid the general collapse around it.

The mill is a rectangular gable-ended structure, roughly twelve metres east to west and five and a half metres north to south, with a three-bay entrance front facing south. At one point a stone platform and cement bridge connected the third-floor door in the western gable to a residential house to the east, an arrangement that suggests the mill and the adjoining dwelling functioned as a single managed property. Inside, the floors are gone entirely, and the stone spindles that once drove the French burr millstones, a type of composite grinding stone made from freshwater quartz and favoured for flour milling, have collapsed to the ground floor. Two pairs of these millstones on the first floor were driven by line shafts, each shaft powered by a pinion wheel off the main waterwheel. A secondary gable-ended structure attached to the north wall still has its roof and floors, though in poor condition, and foundation blocks for machinery survive in the ground floor and in small additions to the north and north-east, even though the gearing itself has been removed. Lying on the ground to the north is a recently removed Crossley engine, a type of internal combustion engine often installed in mills during the late nineteenth or early twentieth century to supplement or replace water power when river levels were unreliable.
