Description
Islip Mill House – An Exceptional Riverside Residence
A truly exceptional Grade II listed former mill house, occupying an elevated position within approximately 1.1 acres of beautiful private grounds on the banks of the River Nene.
Offering approximately 4,150 sq ft of characterful accommodation, including six bedrooms and four reception rooms, this remarkable historic home combines period charm, privacy and versatile living with an extraordinary riverside lifestyle.
With approximately 200 feet of river frontage, private fishing and mooring rights, a boathouse and slipway, Mill House provides a rare opportunity to enjoy life beside the water.
A haven for wildlife, the grounds attract kingfishers, swans, otters and deer, creating an idyllic setting where nature can be enjoyed throughout the seasons.
Steeped in history and renowned for its secluded setting, Mill House has welcomed A-list celebrities and distinguished guests, drawn by its character, tranquillity and exclusivity.
The flexible accommodation also offers potential for guest accommodation or holiday-let income, while the extensive grounds may offer scope for a garage, enlarged boathouse or elegant orangery, subject to the necessary planning and listed-building consents.

Flood Risk
Environment Agency open data, checked around the advertised map pin for the listed acreage. Long-term risk counts flood defences; the planning map's flood zones do not. The map pin for this listing marks the postcode area rather than the exact location, so these readings describe the surrounding area. Provided by LandSale, not the listing agent, and not part of the agent's particulars. Risk varies across a holding, so verify before committing.
