Description
A historic 18th Century former mill spanning over 4,000 sqft, occupying a secluded plot in excess of 1 acre with 200ft of direct river frontage and fishing rights. Situated at the end of a quiet village lane with gated access, this expansive property offers outstanding countryside living whilst still being closely connected to the village and historic market towns of Thrapston and Oundle.
INDOOR SPACE
The accommodation extends across three floors and offers considerable flexibility. The ground floor is introduced by an impressive limestone-floored entrance hall which leads to the scullery, boot room and an impressive dining hall. This space sits at the heart of the ground floor and has a wealth of period-correct features. Adjacent lies the drawing room – also known as the ‘river room’ – which enjoys access to the terrace and far-reaching views across the river. Additional reception rooms include a family room and a breakfast room, each with glorious features and unique garden aspects. The kitchen adjoins the breakfast room and features quarry-tiled flooring, fitted cabinetry, hardwood surfaces, a Belfast sink, and an oil-fired Aga.
The first floor is accessible via two staircases, providing a clear opportunity for adaptable living. The principal suite spans two levels and includes a sitting area, study, and particularly sizeable bedroom with an adjoining highly-specified bathroom. This space can be easily separated from the rest of the sleeping accommodation, offering plenty of versatility. Four additional double bedrooms – one with ensuite facilities – and a family bathroom occupy the main first-floor, with all rooms enjoying views across the river or gardens. Many retain original fireplaces and period joinery.
OUTDOOR SPACE
The house is approached via remote-controlled electric gates set within a high garden wall, leading to a sweeping gravel driveway with turning circle and ample parking. The mature gardens are a highlight of the property, arranged in lawns and terraces with hedging and established trees to the boundaries. A cobbled and flagstone terrace offers a picturesque riverside seating area with open views along the River Nene – a haven for local wildlife including kingfishers, swans, otters and deer to name a few. Beyond the main lawn lies a timber boathouse with slipway and a workshop.
HOLIDAY LET POTENTIAL
A section of the accommodation is used to generate a successful short-term letting income, providing an appealing opportunity for buyers seeking either an ancillary suite or income-producing space without compromising privacy within the main house. Recently part of the property is a successful holiday let.
THE RIVER NENE
The River Nene is one of England’s most beautiful navigable waterways, rising near Northampton and flowing eastward through Northamptonshire and Cambridgeshire to the Wash. The river supports an abundance of wildlife and provides an important navigation link between the Grand Union Canal and the Middle Level system, giving access to Ely, Cambridge, and the wider Fenland waterways. Local marina and boatyard facilities can be found in Thrapston, Oundle, Northampton, and Stanground, with navigation managed by the Environment Agency.
LOCATION
Islip Mill House is situated at the end of Mill Lane, in a tranquil position at the edge of the village and less than a mile from the market town of Thrapston. The area offers an excellent range of local shops, cafés, and leisure facilities, while more extensive amenities can be found in Kettering, Wellingborough, Northampton, and Peterborough, each providing mainline rail services to London in roughly an hour. The region is also well known for its choice of schooling, including Oundle, Kimbolton, and Wellingborough.
