Tunbridge Wells orangery extensions, designed and built
A orangery extension in Tunbridge Wells starts with the right design and the right approval route. We take care of both, then build it with our own project management.

Do I need planning permission in Tunbridge Wells?
In England a glazed or orangery-style extension follows the same size limits as any single-storey rear extension: 3 m or 4 m without an application, or up to 6 m and 8 m through prior approval. Building regulations limit glazing to about a quarter of the new floor area plus the openings it replaces, unless whole-house calculations show the design still performs.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Extensions in and around Tunbridge Wells
Site visits are available across Tunbridge Wells (TN1, TN2, TN3, TN4). We also work in nearby Tonbridge (4 miles), Sevenoaks (10 miles), Maidstone (14 miles), Swanley (19 miles).
For homes towards East Sussex, Crowborough is around 7 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
Included in a typical project
- Heating sized for the glass area
- Foundations, walls and insulated perimeter roof
- Opening into the main house
- Design of piers, roof perimeter and lantern proportions
The lantern-to-roof ratio sets the character. A wider solid perimeter gives a calmer, more room-like space and hides downlights and speakers; a bigger lantern feels brighter but needs more care against summer heat.

Common questions in Tunbridge Wells
Who do I contract with for an orangery extension in Tunbridge Wells?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Will my neighbours in Tunbridge Wells be involved?

Do you cover all of Tunbridge Wells?
Yes. We cover Tunbridge Wells and the surrounding parts of Kent. Site visits are free and there is no obligation.
Will an orangery be too hot in summer?
Not if it is designed with solar-control glass, a solid perimeter and ventilation. We size the lantern and opening vents with that in mind.

Our guide range is about £2,690 to £5,040 per m² including VAT, so a 16 m² standard-spec orangery is typically £50,000 to £63,000 in Tunbridge Wells.
