Built into a slope above the Owennashingann river in the late nineteenth century, the structure is substantial enough to read clearly from the outside: two storeys, five bays across the main elevation, with matching five-bay gable ends and windows finished in brick dressing. The scale suggests serious commercial ambition rather than a modest local grinding operation, and the building was not constructed from scratch. Whoever raised it incorporated part of an older structure, folding an earlier phase of the site into the new build rather than clearing it away.

The most arresting feature sits along the southern elevation: a cast iron overshot waterwheel, measuring roughly 1.9 metres in width with a radius of 3.65 metres. An overshot wheel is driven by water delivered to the top of the wheel rather than underneath it, allowing gravity to do much of the work and making it a relatively efficient design for a site with a reliable head of water. This example has a segment wheel attached to the outside shrouding, with a pinion engaged externally, meaning the gearing that transferred the wheel's rotation into mechanical power was mounted on the outer face rather than carried inside the building. Inside, a large central staircase still rises to the first floor, but no machinery remains. Whatever equipment once filled the interior, whether millstones, shafting, or auxiliary gear, was removed at some point after the mill ceased working, leaving the staircase ascending through empty space.
