Description

Mill House is a house with an attached mill complex located to the north. The building is constructed from rubble, with the front of the house being colourwashed, and it features slate roofs. The house has timber eaves and bargeboards, along with rubble gable chimney stacks and a brick gable stack on the rear wing. The front of the house has three bays, which are offset to the left. It includes four-pane sash windows, with the two on the first floor rising to the eaves and positioned closer to the center. The larger lower windows have timber lintels and slate sills, with the left window set higher. The arrangement of the windows suggests that they were altered in the late 19th century. There is a central boarded door with a cambered stone voussoired head and a modern tablet above that indicates it is the birthplace of D. Wyre Lewis. The later rear wing features four-pane sash windows with brick surrounds, two facing the rear and two to the north, all with slate sills. A small porch is situated in the angle between the wing and the house. The rear of the main house has 20th-century glazing, except for a small sash window on the first floor. The southern end includes 20th-century additions and a conservatory.

Attached to the north of the house is a recessed lower building of two storeys and bays, which forms the grain-drying kiln. This structure was rebuilt in the later 19th century and has a colourwashed rubble front with a boarded door to the right and an upper window to the left, both featuring timber lintels. The rear has a small window with a stone lintel and sill.
