extended to a lower eaves at south and west. The house and mill has a continuous
front (south-east) elevation of 2 storeys, 2 storeys and attic, 4.2 windows, the
mill showing coupled gables of wider span and greater height. casements. Plain
house doorway (early C19) with moulded canopy on small coupled carved brackets and
6-panelled (2 top glazed) door. The mill front has upper and lower doors, and a
wide cambered arch in the northern half, leading to the wheel housing: the lower
walls are of ironstone, where they meet the embankment. The barn (a timber-frame
of 3 bays with 2 aisles) is set back and touches the house at its south-west corner.
The rear elevation of the house indicates by the brickwork that the roof was
formerly a catslide, but was raised to form the gables. A feature of the mill is
the retention of its interior, with machinery, now unusable by the diversion of the
water supply.
