Description
Nant Mill is a large stone-built mill that has been extended to include malting and brewing facilities. The building faces north, with its rear side adjacent to the millpond dam. It is constructed from axe-dressed local stone and features a roof made of small slates. A semicircular archway is located to the right of the center, marking the end of the original structure where the water wheel was situated. Above this archway, there is a gap in the wall about 1 meter wide, which is filled with boarding above a first-floor door. The mill has small window openings across three storeys on the left side and two storeys on the right, retaining only the window frames. There are two attic windows in the right gable that are boarded up. The openings on the ground and first floors have cambered voussoir heads and stable-type doors.
To the left of the mill is a narrower, two-storey, three-bay house that is whitewashed and has a slate roof at the same eaves height as the mill. This house features modern windows and two red brick chimneys, with a door and porch on the left and another door on the right.
Set back on the right side is the original miller's house, built from roughly coursed local axe-dressed masonry. This house has three windows above and two below, all fitted with four-paned horned sash windows, and a door on the left. There is an additional bay on the right, and it also has a slate roof.
The interior was not inspected during the recent survey, but it is reported to retain a significant amount of in-situ mill machinery. This machinery is unusual because it has 'over-driven' gearing, which is typical of windmills but very rare in watermills. The off-centre wheel-pit once contained a large overshot water wheel. The corn mill is said to have three pairs of stones, while the brewery has one pair. The drive system includes a crown spur wheel on a timber shaft with secondary drives.
There are stairs dated 1823 leading to the bin-floor, which has a hopper that descends to the stone floor. The corn mill to the west features a king-post roof, which is noted to include a reused sailing-ship yard, with trusses resting on stepped wallheads and lightly stop-chamfered beams. The former gable end has a splayed recess, and a passage has been created at the first-floor level along the front of the wheelpit.
