Hatcliffe Mill

Hatcliffe Mill is a watermill dating from 1774, with a datestone inscribed "J A". It features a late 19th to 20th century shed over the wheel and an adjoining 20th century engine house. The mill is constructed of colourwashed brick, with ashlar used for the wheel mounting and dressings to the mill race. The millhouse has a Yorkshire flagstone roof, while the wheel-shed has a slate roof and the engine house is covered with pantiles. The mill has an iron and timber wheel and sluice fittings.

The building is L-shaped and built into the side of a valley, with a main north-south range. It has a first-floor entrance at the south gable end, with the wheel located at the rear and an outshut to the right that includes a ground-floor entrance. The structure is two storeys high with an attic and features a three-bay entrance front with an outshut to the right.

On the south front, there is a board door beneath a segmental brick arch, with a datestone above, flanked by two single 2-light casements under segmental arches. To the right, there is a lower single-light window and a ground-floor 2-light wooden mullioned window. The attic has a shouldered round-headed window. All windows have 20th century glazing in their original openings. The graduated flagged roof is likely unique in Lincolnshire and South Humberside.

The east side features a board stable door with a 4-pane overlight beneath a segmental brick arch, along with a blocked opening to the right. The west side has a single ground-floor window and a 3-light first-floor casement, with stepped eaves. The north side of the main range, above the wheel, has a pair of 2-light first-floor casements and a shouldered round-headed window similar to the front.

Inside, the ground floor has stone flagging, while the upper floors are at a lower level in the outshut. There are iron pulley-drive wheels on the ground floor. The ceiling features chamfered beams and a queen-strut, with a staggered butt-purlin roof supported by a ridge-piece and small, shaped king-struts. The flagstone tiles are secured with bone pegs. Hatcliffe Mill is a notable early example of a building type that is rare in the Humberside and Lincolnshire region, distinguished by its quality of design and workmanship, as well as its flagstone roof. At the time of the last survey, the mill was disused and partly in decay.
