The mill section has a single square window opening to the centre with 2 similar windows flanking above, beneath the eaves; pegged wooden frames and internal boarded shutters. To the L a large, later C19 rubble buttress. Large overshot waterwheel to L gable end, of iron and timber construction. Central upper entrance with catslide dormer roof to rear; boarded door. Plain entrance to L on road-facing face of carthouse; large, plain cart entrance to R gable end.
