An overshot wheel is one of the older and more efficient configurations of watermill technology, where water is directed over the top of the wheel to drive it by weight rather than impulse alone. The fact that its successor, an inward-flow turbine housed in the original wheel pit along the north elevation, still powers the mill through a system of belts and pulleys makes this a genuinely unusual survival. Most rural Irish mills of this type were either abandoned or gutted during the twentieth century; this one kept working.

The complex is L-shaped and multiperiod, meaning it accumulated function and fabric across several generations of use. The western section, according to the miller who provided much of this detail, served as a carding mill during the nineteenth century. Carding is the process of combing raw wool fibres into alignment before spinning, and its presence here points to a time when this stretch of water was doing several kinds of industrial work at once. A tuck mill, used to full or finish woven cloth by beating it in water, stood to the east along the same mill race. That structure, a small single-storey rectangular building from the mid-nineteenth century, survives in a rather altered state. The miller recalled it once having a fourteen-foot wooden water-wheel, two feet in width, along its north elevation. It is now used as a piggery. Back in the main mill building, the first floor retains a pair of enclosed French burr stones, the type of millstone made from freshwater quartz quarried near Paris and long favoured for producing fine flour, alongside a Robinson Roller Mill and a Bramford rapid hammer mill, each representing a different era and method of grain processing layered into the same building.
