Hand Forge, North Mill Building and South Mill Building at Churchill Forge

Three forge buildings most likely dating from the early 19th century, with water-powered machinery for the production of tools and hand implements.

The buildings are constructed of brick with corrugated sheet roofing on two buildings and a tiled roof on one. Windows are mostly metal casements, with timber and some metal doors. The three buildings are arranged roughly parallel to each other and orientated east to west. Between the southern buildings is an open courtyard where the two water wheels are housed, and there is an open, freestanding metal structure with a corrugated sheet roof. To the east of the buildings is a large dam which retains the mill pond beyond, which has two sluices: one controlling the flow of water to the wheels and the other controlling the overflow leat. The overflow leat runs west and south-west where it joins the tailrace leat flowing south-west.

The northern building, known as the Hand Forge, sits at a slightly higher level than the two southern buildings, and is a single-storey brick building with a pitched roof with corrugated sheet covering. The brick is laid in English Garden Wall bond. In the southern elevation are a door and window opening, with a timber boarded door and timber boarded shutters. There is a brick chimney on the ridge which appears to have been rebuilt. The western elevation has a timber shuttered opening with an arched head, and a square chimney on the north-west corner. The northern elevation has one shuttered opening. Internally, the building is understood to contain two hearths and a kick hammer.

There is a lean-to structure at the eastern end which joins this building with the North Mill Building. This building is of brick, also in English Garden Wall bond, with a tile roof which contains some modern glazed rooflights. The roof is pitched and in a T-plan, with a lean-to section to the east with a modern covering, and a chimney on the northern elevation. The building's southern elevation has a dentilled cornice with a door and window opening at its western end. Adjacent to the east of these is an overshot cast iron water wheel which is approximately 5 metres in diameter, with 48 steel buckets and eight wooden spokes, with a cast iron header tank and pipe above. Internally, the building retains much historic machinery, including a drive belt system, a drop hammer, two pneumatic hammers and a press. The hearth is along the northern wall. To the east, the former grinding shed is now used as an exhibition space.

The South Mill Building is also of brick, laid mostly in stretcher bond, with a corrugated sheet roof, with a chimney at the western end. There are two window openings in the southern elevation. The northern elevation has a door and window opening, and east of these is an overshot cast iron water wheel, approximately 5 metres in diameter. The wheel has seven cast iron spokes and 49 buckets. Internally the building retains some historic machinery, and a hearth in its south-eastern corner with a chimney now truncated.
