Turbine House

Turbine House is a complex of buildings dating from the 19th century, originally constructed as a turbine powered facility. It comprises two parallel ranges running north-south, with a further range across the southern end projecting slightly to the west. The structure is primarily built of roughly coursed stone with rock-faced quoins, and is roofed with tiles. Timber framing is visible in the north and south gables, featuring hollow moulded tie beams and wide barge boards. The north gables incorporate diagonal struts, while the single gable to the south has vertical struts, and includes an external stack offset to the left, rising to an octagonal stone shaft. A hearth recess sits at the base of the stack, contained within a cast iron frame.

The main entrance is on the north side, located under the right-hand gable, and features double-planked doors set within a segmental stone head, which appears to have been widened. A small two-light window is situated under the left-hand gable, also with a segmental stone head. The remaining window openings have flat stone lintels and stone sills, now featuring late 20th-century windows with horizontal glazing bars. There are two windows on the west side, one in the projecting gable end, and a single window in the south wall to the left of the stack. The east wall is built into the bank, with a gabled half dormer to the left containing a window similar to the others. Below the dormer is a recess with a cast iron lintel, followed by a window, and then a former doorway - now infilled with a window - under a segmental head of voussoirs. A further window is located to the right. A red brick boundary wall runs north, beginning at the northeast angle.

The internal layout consists of three bays in each range, with king post roof trusses. The valley between the two parallel ranges is supported by two steel columns and a girder. A dividing wall runs down the centre-line of the east range, immediately east of the stack, creating smaller rooms beyond. A doorway is located to the left, under a segmental brick head with a late 20th-century door, and a further projection has another doorway. The windows include relieving arches.

The original turbine is housed within the projection at the west end of the south range, now encased in a late 20th-century brick structure. The turbine wheel itself has a riveted metal casing, bearing the makers stamp "Gilbert Gilkes & Co, Kendal." A large, circular pipe connects to the wheel casing from the north, while outlet pipes extend from the east and west faces, curving downwards into a tail race. A valve mechanism for controlling water flow is situated along the top of the west face, consisting of a turning wheel, metal rods, and a small gear wheel. An axle projects from the east side, supported on a bearing but not extending further.
