Swafield Mill was a three-storey building, with a brick base, weatherboarding on the middle storey, and the upper storey built into the pantiled roof. Water was taken from the River Ant, and was used to drive two sets of stones and two flour mills in 1831. By 1967, only the brick base remained, as the mill pond had been filled in. However, the mill house, which was constructed in the mid-eighteenth century, remains and is grade II listed. It is built of brick with three storeys and three bays, with a roof of black glazed pantiles.
