Description
Walton Mill House is a mill house dated 1800, featuring the initials TW and RF on its front elevation, but it also incorporates a fragment of an early 16th-century building. The main structure is L-shaped, with the main building located to the south and an early 19th-century one-storey addition to the north. The main building is constructed of red brick in English bond, topped with a peg-tiled roof and a brick chimneystack on the north side. It has three storeys and three windows, with 20th-century wooden casements fitted into the original openings, which are cambered on the lower floors and blank in the center of the second floor. The building features brick corbelled eaves and a central doorcase that includes a rectangular fanlight, a six-fielded panelled door, and wooden brackets supporting a 20th-century tiled pent roof.
The early 19th-century wing to the north is made of painted brick and has a half-hipped tiled roof with a brick chimneystack at the rear. This wing contains two 20th-century casements and a boarded door at the time of the survey, along with brick buttresses on the side elevation and a 20th-century lean-to extension at the rear. Inside, the ground floor south room features an open fireplace with a curved wooden bressumer dated 1523 and the initials JM, along with two salt recesses and two curved wooden seats. The spine beam has a two-inch chamfer with lambs tongue stops. The staircase, dating from around 1800, includes a column newel and retains old floorboards and doors, one of which has tapering planks.
