Extensions in Tunbridge Wells
A home extension adds new floor space to an existing property — commonly a rear or side-return kitchen extension, a wraparound, or a first-floor addition — and typically involves planning or permitted development approval, Building Regulations, and coordination of groundworks, structure, roofing and internal finishing.
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.

FAQs
Extensions in Tunbridge Wells: FAQs
Do you provide extensions across all of Tunbridge Wells?
Yes, we cover the TN1 and TN2 and 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 a rear extension?
Many single-storey rear extensions fall under permitted development if they meet size, height and boundary criteria. Larger extensions, those on designated land, or properties where permitted development rights have been removed, need a full planning application. We assess this during the feasibility stage.
What is a party wall notice and do I need one?
If your extension involves work at or near a shared boundary, the Party Wall etc. Act 1996 usually requires you to notify your neighbour before work starts. We flag this during design so notices can be served in good time.
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.
