Watermill, Old Bridge Of Urr

The site comprises a watermill with associated buildings, dating from the 18th century. The mill building stands to the south, with a kiln range to the north, and a cottage adjoins to the northeast.

The mill range features an enclosed water wheel flanked by a single-storey threshing barn to the west and a grain mill and stores/ancillary buildings to the east. The water wheel is located within a small, rubble-walled wheelhouse with a graded slate lean-to roof. It is a high breast-shot wheel, incorporating wooden paddles, arms and sole plates, cast iron sideplates, a hub and axle. The grain mill retains much of its original machinery. Adjoining the grain mill to the east is a single-storey rubble barn/storage area, all with slated roofs.

To the north, the kiln range consists of a two-storey painted rubble structure with cast-iron columns supporting a perforated sheet metal kiln floor, and slate roofs with a ventilator. To the west of the kiln is a single-storey and loft range, featuring a rubble-built north wall built up to accommodate the rising ground, and an open cart shed at ground level. A granary is located in the loft, with front walls of vertical timber board, beneath a corrugated-iron roof. To the west stands a tall, single-storey garage/storage building with a brick party wall and vertical timber boarding, topped with a corrugated-iron roof.

The mill cottage is a single-storey and attic structure of painted rubble, featuring sash windows with plate glass glazing. Gablet dormers are visible to the north, and the slate roof has raised skews and ceramic ridge end coped stacks. A lean-to single-storey extension projects to the south.

The buildings are significant due to the survival of the mill machinery, notably the timber-framed water wheel, which is considered unique in Scotland. The positioning of the kiln in a detached range of buildings is also rare.
