Description

Balnakeil Mill is an early 19th-century, two-storey, rectangular-plan, gabled former water-powered grain mill located on a sloping site. It features a man-made embankment leading to a first-floor entrance at the rear. The building is constructed of roughly coursed rubble with sandstone dressings, showcasing long and short quoins and window margins. The principal elevation faces northeast and includes a central door with a window to the right. The entrance doorway has a piended roof that breaks the eaves on the southwest elevation. The gables display irregular fenestration, with an opening for the water wheel shaft at the lower ground floor of the southwest gable, a small opening above to the right, and another central opening at the first floor. The roof is finished with ashlar-coped skews and graded grey Scottish slate, and there is a flue aperture in the ridge to the north for the kiln.

Inside, there are significant remains of grinding machinery and a gear cupboard located at the ground floor in the southern end of the mill. The mill wheels, set in a timber frame, are situated directly above on the floor. There is a circular, stone-lined kiln with sloping sides at the northern end. The gear cupboard contains a wooden bridge piece, grain shoot, and surrounding wooden partitions that remain in place. Some spur gear machinery is still present, including a wooden mill-stone drive wheel, belt-drive wheels, and iron cogs. The floor is made of stone flags, and the roof timbers and beams have been reinforced with additional timbers along the eastern side.

The mill lade, which is now partially in ruins, is lined with concrete and stone and runs from Loch Croispol to the south, with a narrower section extending along the eastern side of the mill towards Balnakeil House.

Local climate

Balnakeil Mill sits in one of the wettest parts of the UK, with an average of 1,530 mm of rain a year. This makes it wetter than 99% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 99% of listed buildings.

It experiences an average of 13 freeze-thaw cycles a year, fewer than 87% of listed buildings. Of these, 11 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.2°C per decade since 1991.
