About this property

Exquisitely restored country house in a tranquil position.

Positioned in the peaceful hamlet of Slapton, just four miles from Towcester, Slapton Mill stands as one of the area’s most character-rich and historic homes — a beautifully converted former watermill with origins reaching back to the 14th century. From its earliest mention in medieval court rolls to its modern life as a private home, this is a property with genuine narrative depth. Few homes in Northamptonshire can boast such continuity of place — a landmark woven into the landscape for over 600 years.
