Description
Old Mill House is a 18th-century building that has been altered and stands three storeys high. It features a brick parapet with stone coping and an old tile hipped roof. The front has two bays with slight projections that extend to the full height of the building. The left projection includes a square sash window set in an arched recess on the second floor, along with a three-light sash window on both the first and ground floors. The right projection mirrors this with a similar recessed window on the second floor, a French casement window to the right of centre on the first floor, which is accompanied by a 19th-century cast iron balcony, and a single sash window on the ground floor. To the left, there is a later one-storey porch featuring a recessed six-panelled door. On the right, a later two-storey extension has French casement windows on the first floor, a similar cast iron balcony, and one window on the ground floor.
