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.

WHOTS analysis

Our WHOTS verdict

An internal assessment of the opportunity to acquire, improve and create value.

83out of 100
Grade AStrong opportunity

Confidence: MEDIUM

At £1,000,000, this is a strong-value way into a distinctive Rushmore Hill project: the asking price works out at £313/sq ft, around 40% below the local average. The established gardens, extensive hardstanding, stables and existing annexe give the site character and flexibility, while the dated but apparently usable kitchen and bathroom offer scope to refresh the existing accommodation.

The standout opportunity is the listing’s stated full planning permission for an approximately 3,200 sq ft contemporary Kentish barn, alongside retention and conversion of the existing accommodation and proposed landscaping. The new house, pool and landscaped scheme are shown in CGI, not as completed works, so this is a substantial build-and-delivery project rather than simply a cosmetic update. Verify the permission, conditions and implementation status, as well as the condition and lawful use of the annexe and outbuildings.

Key opportunities

  • Create the proposed approximately 3,200 sq ft contemporary Kentish barn under the stated planning permission, subject to verifying its conditions and implementation status.
  • Make use of the existing two-bedroom annexe for independent accommodation while the main house is built, or for family, guests or another suitable use subject to consents.
  • Work with the established gardens, patio, cobbled courtyard, hardstanding and stable-like outbuildings as the setting and facilities for a distinctive rural property.

Key risks

  • Delivering the proposed new residence, retention and conversion works, and associated landscaping is a substantial construction programme and budget commitment, not a cosmetic refresh.
  • The condition and lawful use of the annexe, outbuildings and services are not established; verify these before relying on their current or proposed uses.
