Bonsons Mill House with Attached Mill

Bonsons Mill House with an attached mill is a house dating from 1734, although it was all rebuilt in the early 19th century. The house is constructed of coursed rubble that is colourwashed, featuring a rubble parapet with a coping and a pantile roof with coped verges and end brick stacks. It has a symmetrical frontage with two storeys and a basement, consisting of three bays. The windows are 16-pane sash windows with glazing bars, except for the central first-floor window, which has a semi-circular head in a Gothick style. The basement has an open arcade of three semi-circular archways leading to brick-lined vaults. The central entrance features a six-panelled door with a semi-circular head opening, a fanlight with glazing bars in a Gothick style, and a metal hood supported by paired scrolled wrought-iron brackets, with stone steps leading down to the basement area.

The attached mill to the left is also built of coursed rubble and has a hipped triple-Roman tile roof. The ground slopes away from the house towards the mill, making the basement of the house an additional storey for the mill, which has three storeys. The mill features irregular window and door openings, many with cambered heads and brick voussoirs, as well as two and three-light mullioned windows and iron stanchions, some with leaded lights. There are four door openings on the ground floor with plank doors, and three additional door openings on the first floor. A semi-circular archway on the left side of the ground floor, with brick voussoirs, marks where the former mill-leat exited the building after passing over the internal overshot mill wheel. Most of the milling mechanism has been removed, but two mill stones remain in place on the first floor. Together, the house and mill create a picturesque unit.
