Annexes in Tunbridge Wells
An annexe is self-contained living accommodation on the same plot as a main house, complete with its own kitchen and bathroom facilities, built either as a new detached structure, a conversion of an existing outbuilding, or an extension with its own entrance.
In Tunbridge Wells, that covers Southborough, Rusthall, Pantiles, Broadwater Down, St John's, High Brooms, Culverden. Royal Tunbridge Wells developed as a Georgian and Victorian spa town, with the historic Pantiles and surrounding conservation areas at its centre, and a wide range of substantial Victorian villas and later housing across the wider town.

The town has a strong stock of Victorian and Georgian villas, many on generous plots suited to rear and wraparound extensions, alongside interwar and later housing in the surrounding suburbs and villages.
Planning considerations
Tunbridge Wells Borough Council is the local planning authority. The town centre and several residential areas are conservation areas, and the borough includes parts of the Kent Downs National Landscape (formerly AONB), both of which influence design and materials for extension work.

FAQs
Annexes in Tunbridge Wells: FAQs
Do you provide annexes across all of Tunbridge Wells?
Yes, we cover the TN1, TN2, TN3 and TN4 postcode areas in full, including Southborough, Rusthall, Pantiles, Broadwater Down, St John's, High Brooms, Culverden.
Do I need planning permission for an annexe?
Usually yes, because independent cooking, sleeping and washing facilities mean the structure is not treated as a simple outbuilding. Some annexes intended purely as ancillary accommodation for the main house can fall under permitted development, but this depends on size, position and local policy, which we check during feasibility.
Can an existing garage or outbuilding be converted into an annexe?
Yes, provided the structure is suitable and can be brought up to full Building Regulations standard for insulation, damp-proofing and services. We assess this as part of the feasibility stage alongside a new-build option.
Are there conservation areas in Tunbridge Wells beyond the town centre?
Yes, several residential areas of the town also carry conservation area status. We check the specific designation for your address as part of the feasibility assessment.
