The Old Mill with Attached Wall to North West

The Old Mill with an attached wall to the northwest is an 18th-century mill that was heightened and had wings added in the early 19th century. It is constructed of tooled stone and features a Welsh slate roof. The main block is rectangular and three stories high, with an external wheel located at the south end and tower wings on both the east and west sides.

The west elevation has three stories and two bays. The ground floor includes a boarded door on the left and a projecting gabled wing on the right. The first floor features 9-pane and 4-pane casements, while the second floor has part-slatted windows. There are remains of blocked 18th-century windows in the lower part of the wall. The gables are coped, and there is a stepped-and-banded stack at the left end. The wing has a doorway and a window on the left return, a cast-iron slatted ridge vent, and a stepped-and-corniced end stack. The attached wall, which is 15 meters long, is located on the far left and has a chamfered setback at mid-height with gabled coping.

The left return has two steps leading up to a central boarded door. The rear elevation features a central projecting wing flanked by blocked windows, with two part-slatted windows on the second floor. The wing has an arched opening beneath a part-slatted window in the end wall, chamfered eaves cornices, and a hipped roof. There is an external stone stair leading to a boarded door on the right return. The right return of the main block shows fragmentary remains of the wheel and a central first-floor window.

The interior has been altered, but the west wing contains remains of a drying kiln.
