Hannover Mill, Outbuildings And Mill

Hannover Mill, along with its outbuildings, is a mill and mill house that has an 18th century or earlier core but was remodeled and significantly extended in 1879. The milling machinery was made by Holmans of Canterbury. The structure is primarily red brick, with some sections featuring tile hung framing, and it has a plain tiled roof. The layout is in a half-courtyard plan.

The main range consists of two storeys and an attic. The house section on the left has bracketed eaves that return to a hipped roof with a stack at the left end. On the first floor, there is a margin light sash window and a blank name plaque, while the ground floor features a margin light sash window alongside a six-panel door with a rectangular fanlight above, both adorned with cornices on brackets.

To the right is the mill building, which includes two hipped dormers and two segmentally headed casements on each floor, with boarded doors situated between them on both levels. Adjacent to this is a three-storey block with a half-hipped roof and a central stack, featuring one wooden casement on each floor and an open passageway doorway on the ground floor.

Further to the right is a projecting two-storey framed range, with tiles over brick. This section has a wooden casement on the first floor, a boarded loft door, and three boarded and half-glazed doors along with a mullion and transomed shop window on the ground floor. The three-storey end block has a returned half-hipped roof and includes two wooden casements on the second floor and one each on the first and ground floors, with a boarded door on the first floor to the left and a half-glazed door on the ground floor.

The rear elevation features tile hung upper storeys on the main mill building. There is also a small single-storey brick out-house with a wooden casement. The brickwork is set on ragstone sluice and race walls, which extend about 20 meters upstream, and the entire mill complex is built on ragstone reinforced walls alongside the stream. Iron sluice gates are present, along with a passage over them. The mill features a 12-foot diameter breast-shot wheel with 56 buckets, originally driving three sets of stones, though it now only drives two. The entire wheel and machinery are enclosed within the mill building.
