Description

Kemyel Mills, also known as the Lower Mill Building, is a watermill that possibly dates back to the 17th century. There is a jambstone set into the side of the doorway inscribed with "IH I 1674," although this may be a reused stone. The building features granite moorstone rubble walls with some dressed granite and has gable ends. It has a small rectangular plan and includes a 20th-century wheel at the right-hand end. There is no old internal machinery remaining.

The exterior is single storey with a simple design. It has a window on the front right-hand side, a doorway in the middle of the left-hand gable end, and openings for machinery at the other end. Above the doorway, there is an inscription that reads "SH 1974 OH," along with a ventilator window above it. The interior is simple and unplastered, with the machinery having been removed.
