Mill Dam House with Barns Attached to North and South Ends

A late 17th or early 18th century farmhouse with attached barns to the north and south. The farmhouse is built of white-painted random rubble with quoins, and has a stone slate roof. It has a single-depth, two-unit plan aligned along a north-south axis, facing east, with a broad rear wing and a lean-to addition in the angle between them. A large barn extends south, and a smaller barn extends north.

The exterior has two storeys plus an unexpressed attic, and five windows. The ground floor centre features a square-headed doorway. To the left are two small, two-light casements, the first containing the rubble voussoirs of a former segmental-headed opening above it. To the right is an oblong, three-light casement, and beyond that a rectangular top-hung casement. The upper floor has five similar top-hung casements grouped two and three. Wrought-iron gutter brackets run along the barn to the left. A small extruded gable chimney is to the right, and a ridge chimney is at the junction to the left. The north gable has a small, blocked attic window. The barn to the left has a wagon doorway with a timber lintel and board doors, and a square-headed stable door to the left. The lower barn to the right features a prominent lean-to in the centre and a wagon doorway immediately to the right with harr-hung doors.

At the rear, the wing’s gable has irregular fenestration, including rubble voussoirs of two former windows at ground floor, and a blocked one-light window to the left at first floor. There's a corbelled chimney with a short cylindrical shaft, the extruded stack rising in two sideways steps from corbels offset to the right, similar to that on the rear wing of Gawthrop Hall. The lean-to has a chimney, and the barn to the left has a segmental-headed wagon doorway with rubble voussoirs.

Inside, a light partition wall is on the right-hand side of the entrance hall, with a muntin-and-rail panelled door. There is an open-well staircase with a closed string, square newels, and turned balusters.
