About this property

A stunning mill house and guest cottage, steeped in history and set in verdant waterside gardens.

The House.

This property represents a rare opportunity to purchase one of the few surviving mill houses in the country. Access to the house is gained through wrought iron gates adjacent to a castellated gate house and brick walls which form the remains of the Old Mill with its two mill wheels. A large paved courtyard leads to the house.

The agent hasn't said which band this home is in; you can look it up on GOV.UK. In Three Rivers, 2026/27 bills run from £1,615 a year in band A to £4,845 in band H.

Figures from MHCLG (Open Government Licence v3): the average bill for each band across Three Rivers, including the typical parish precept, so a parish's own bill can differ a little. Discounts lower the bill, such as 25% off for an adult living alone.
