A 19th-century building of brick and stone, from Redford near Midhurst, designed to house a pugmill and the horse turning it. It is six-sided, and the diameter of the internal walking circle is seventeen feet.
A pugmill is an upright barrel, open at the top, which contains blades attached to a vertical shaft turned by a horse. The clay was churned and mixed, then emerged from the base of the barrel as a smooth and workable paste ready for moulding. This mill came from a brickyard at East Grinstead.
