Gretton Mill

Gretton Mill is a watermill and mill-house that has been converted into a farmhouse, dating from the early to mid-19th century. It is constructed from roughly coursed yellow sandstone rubble with red brick window dressings and features a plain tile roof. The building stands two storeys high, with the site sloping from east to west. It has an off-centre brick ridge stack to the east and an integral brick end stack to the west.

On the south front, there are a pair of first-floor two-light small-paned wooden-framed metal casements to the left, and on the ground floor, a segmental-headed two-light wooden casement to the right, along with a three-light wooden casement to the left flanking a segmental-headed boarded door. The former mill section to the right has a boarded door and a casement under a large segmental head, with a lean-to to the right featuring a boarded door on its left-hand return.

At the rear, there is a one-storey lean-to to the right with an integral brick stack and a segmental-headed boarded door leading to the first floor of the mill on the left. The wheel pit is located adjoining the gable end to the north, with rubblestone retaining walls; although the waterwheel was missing at the time of the survey in September 1985, the axle and access hatches from the mill remain, and the former supply pipe is still embedded in the roadway to the north.

Inside, the mill retains complete fittings and machinery, including storage bins in the loft, a bag hoist and hatches, grain chutes with canvas end covers, and two pairs of stones behind a boarded screen, along with shafts and gearing. The interior of the house was not inspected. It appears that the house and mill were built at slightly different times, as indicated by a straight joint in the south front. Despite the absence of its waterwheel, Gretton Mill is notable for preserving all its internal fittings and machinery and is part of a complete mill group that includes a former stable to the east.
