The neighbouring Grade II*-listed windmill, Stevens' Mill, forms part of the museum and opens with it. It was probably built about 1820. It stayed in the Carter family until 1884, when it was sold to George Mason, who had been the tenant miller. By the 1920s, the mill, at one time powered also by steam, was owned by the Stevens family. When Warren Stevens retired in 1955, the mill became redundant and fell into disrepair. The Burwell Museum obtained funding of £400,000 from Heritage Lottery Fund to restore it.
