The existing mill dates back to the early 19th century, but its history can be traced as far back as the Norman invasion, having been referenced in the Domesday Book in 1086. For centuries, it formed part of the Betchworth Castle estate, and today it stands as a remarkable blend of contemporary living and historic charm.
The accommodation is both spacious and highly versatile, arranged over four floors and presented to an exceptional standard. Throughout the home, the seamless integration of contemporary design with historic character is evident, with the majority of rooms offering breathtaking views across the garden and North Downs.
The grounds of Castle Mill complement the property beautifully, extending almost exclusively to the rear. A raised terrace sits beside the mill wheel, offering a tranquil space for al-fresco dining with stunning views over the gardens, the mill pond, and further afield towards the River Mole. The gardens have been meticulously maintained and are well planted, with mature trees providing privacy. A deck by the water offers a serene sunbathing spot, while the mill pond is graced by a picturesque bridge at its mouth. To the front, there is a dedicated parking area and a detached double garage.
The ground floor features two entrances, one through the traditional double doors that open into an entrance hall, where the mill’s original workings are on display, and another through a striking set of glass doors leading into a large reception room. This space offers flexibility for a home gym, yoga studio, office, or additional living area.
A stunning glass staircase ascends to the first floor, where expansive open-plan living unfolds. The dining area, living space, and a cosy snug create a sociable and elegant setting. The snug is particularly unique, perched above the mill wheel with uninterrupted countryside views. A large working fireplace provides a cosy retreat in winter, while vast windows flood the space with natural light. The contemporary kitchen is a sleek and stylish haven, featuring a central island, high-end cabinetry, and a glass balcony that overlooks the country lane.
The upper levels offer five flexible bedrooms. The second-floor principal suite enjoys a triple-aspect outlook and an adjoining en-suite bathroom, while three further bedrooms share a beautifully appointed shower room. The third floor is a private retreat, offering a double bedroom, an expansive en-suite bathroom, and a study area—ideal for guests or as a secluded work-from-home space.
