The oldest surviving structure of the building date from 1630, at which time it was timber-framed and had a single breastshot wheel.

[2] The mill machinery was restored by Cyril & John Boucher during 1975–7, with partial funding from the Science Museum.

The upper storey, which contains four millstones, is entered by a steep internal stairway, and the grain loft is accessed by a ladder.

It is open to the general public on advertised days during April–September between 1pm and 5pm, and whilst access to the site is free, there is a small charge for a guided tour of the mill's interior if required.

In addition to the working mill, there is a shop and exhibition area in the former stables, outdoor picnic tables, and accessible toilet facilities.

Guided tours for groups (both during and outside normal opening hours) can be arranged in advance, and there is an education programme available for schools.
