Manderston Mill House

Manderston Mill House is a mid 19th century, two-storey, three-bay house that has undergone later alterations and additions. The building features harl-pointed roughly stugged sandstone with droved dressings on the south elevation, while the north, east, and west elevations are made of harl-pointed rubble with droved ashlar dressings. The structure includes long and short flush margins and quoins.

On the south elevation, the house is symmetrically arranged with three bays grouped towards the center. There is a panelled door in the middle, topped by a three-pane rectangular fanlight, all set within a polished ashlar consoled and corniced doorpiece. Above the door, there is a window on the first floor, with a window in each storey of the flanking bays.

The north elevation features a stair window at the first floor center. To the left, there is a later single-storey half-piended addition, which includes a boarded door in the center flanked by a window. A modern harled addition is located in the center with a window.

The house has border-glazed timber sash and case windows, except for those in the additions. The stair window includes colored glass in its border. The roof is piended and platformed with slate, featuring brick wallhead stacks on the east and west sides.

Inside, the house retains shutters. The principal ground room and first-floor principal rooms have a timber chimneypiece with a cast-iron omega-shaped grate. The staircase features a timber handrail and banisters.
