Description

This unique development opportunity on prestigious Rushmore Hill presents a rare chance to create an exceptional architect-designed country home in the sought-after Sevenoaks area. With full planning permission already granted for an impressive contemporary Kentish barn of approximately 3,200 sq ft, designed by award-winning RX Architects, this property offers more than just a traditional development. The plans include the retention and conversion of the existing accommodation, extensive landscaping, and a lap pool, providing a flexible living arrangement rarely found in such properties. The proposed main residence will feature a striking four-bedroom contemporary Kentish barn that harmonizes with its rural surroundings while offering beautifully considered accommodation. Large areas of glazing and generous living spaces will enhance the connection between the house and its landscaped environment, creating a substantial and highly individual home. Additionally, the existing two-bedroom annexe extends to approximately 640 sq ft and includes a kitchen, bathroom, living room, and two bedrooms. This flexible space can serve various purposes, from guest accommodation to a home office or studio, making it ideal for multi-generational living. This arrangement allows for independent accommodation during the construction of the new main residence. The grounds are equally impressive, featuring a formal garden with established planting, a paved patio, and a charming Victorian-style greenhouse. Equestrian facilities include luxury Monarch stables and additional storage options, providing versatility for hobbies or workshops. The enclosed courtyard setting offers privacy and character, perfect for entertaining or leisure activities. Set in a desirable location with open meadows and fields beyond, this property combines the tranquility of rural living with excellent connectivity to Sevenoaks and beyond. The hard work of securing planning permission has already been completed, allowing the new owner to move forward with their vision for this exceptional home.

42out of 100
Grade ELow opportunity

Confidence: LOW

This unique development opportunity on Rushmore Hill presents a compelling project for those looking to create a bespoke country home. With full planning permission in place for a contemporary Kentish barn of approximately 3,200 sq ft, the potential for a striking new residence is significant. The existing two-bedroom annexe adds to the appeal, offering flexible living arrangements or the chance for rental income while the main house is constructed.

However, the asking price of £1,000,000 appears dear when compared to the local average sale price of £697,716. While the headline price may seem attractive, the lack of specified floor area limits how we can assess true value here. Nonetheless, the property’s strong development potential and the flexibility of the annexe present a worthwhile canvas for improvement and personalization.

Key opportunities

  • Full planning permission for a contemporary Kentish barn, allowing for a bespoke design.
  • Existing two-bedroom annexe provides flexible living options or rental potential.
  • Capitalize on the property's location and surrounding countryside for a stunning new build.

Key risks

  • Asking price is relatively high compared to local average sale prices.
  • Potential planning conditions may affect the development process.
