The 2½-storey mill is built of rubble stone with tooled dressings, and slate roof. Arched openings have prominent keystones. The central entrance is a replacement door under a stone lintel. A replacement segmental-headed window is to its L, and a wide arch to a through passage is on the R side. In the upper storey are central boarded doors, incorporating glazed panels, and 3-light windows to the R and L. In the R gable end, above the Mill Cottage roof, is a blocked loft opening. In the L gable end is the wheel chamber, with added roof and doorway to the front, dating from its conversion to the generation of electricity.

In the rear elevation, the wide passage archway is to the L, to the R of which are 2 blocked doorways. A 3-light segmental-headed window is to the L in the upper storey. On the R side is a lean-to, which has an opening with a segmental tooled lintel and corrugated iron roof, against a stone wall that supported the head race. Next to it, also built against the head race wall, is a corner brick fireplace of an additional range now taken down. The head race wall has a round arch with freestone voussoirs and keystone inscribed 1848.
