MCIAT chartered architectural technologists covering Tunbridge Wells and the wider Kent commuter belt from our London base. Planning permission, building regulations, loft conversions, extensions and mansard roofs, 30% below typical London architect rates.
Tunbridge Wells is in Kent, not London, so the London Plan does not apply — but the permitted development order and the application fees are national and identical. Much of the town centre sits inside a conservation area and part of the borough is in the High Weald National Landscape, where Class A is switched off.

Local planning contextRegency spa town granted its "Royal" prefix in 1909; widely regarded as one of the best-preserved historic towns in the South East.
All householder planning applications in Tunbridge Wells are determined by Tunbridge Wells Borough Council. The council follows the National Planning Policy Framework and its own adopted Local Plan, supported by area-specific design guides and Supplementary Planning Documents.
Conservation areas: Tunbridge Wells has 14 conservation areas, including Royal Tunbridge Wells Central, Mount Sion and the Pantiles. Many homes are within the High Weald AONB.
Policy quirks to watch: Tunbridge Wells has extensive Article 4 Directions removing PD rights across its conservation areas. The High Weald AONB management plan applies tight controls on roof alterations, extensions and materials.
Typical housing in Tunbridge Wells includes regency and early Victorian townhouses around the Pantiles and Mount Ephraim, Decimus Burton villas, Edwardian terraces, and Arts and Crafts homes in Rusthall and Langton Green. This mix drives the types of projects we most often prepare drawings for here.
Five core services, all delivered by MCIAT chartered architectural technologists, all within our 50-mile service radius.
Full planning submission: existing/proposed plans, elevations, site plan, and Design & Access Statement.
Construction-detail drawings for your builder and Building Control submission.
Rear dormer, hip-to-gable, L-shape or mansard loft conversion drawings.
Single-storey, double-storey, wrap-around and side-return extension drawings.
Full mansard conversion drawings with structural and thermal detailing.
Every drawing is signed off by a Chartered Member of the Institute of Architectural Technologists. The same quality bar that applies to our central London projects applies to our Tunbridge Wells work.
We regularly submit to all M25 commuter-belt councils including Tunbridge Wells Borough Council. We research each council's Local Plan, design guides and recent decision history before we start drawing.
No mileage charges, no hourly rates, no surprises on the invoice.
Our submissions across the 33 London boroughs and the M25 commuter belt are prepared for council review before submission. This helps reduce avoidable resubmission risk and delay.
Rear and side-return extensions on Tunbridge Wells's Victorian and Edwardian terraces are among the most common projects we handle. A single-storey rear extension of up to 6 metres is often achievable without full planning permission, though conservation-area status (see Tunbridge Wells Borough Council guidance) typically removes Permitted Development rights.
Tunbridge Wells Borough Council application fees are charged separately at the statutory rate.

We cover all Tunbridge Wells postcodes (TN1, TN2, TN3, TN4) for planning permission drawings, building regulations drawings, loft conversions, house extensions and mansard roofs. Tunbridge Wells is 33 miles from central London (48 min from London Charing Cross), so our team can comfortably visit for measured surveys and pre-application meetings with Tunbridge Wells Borough Council.
These prices are roughly 30% below typical London architect rates for the same scope of work. Tunbridge Wells Borough Council application fees are charged separately at the statutory rate (£548 for a householder planning application, £274 for a Lawful Development Certificate in 2026).
Yes, every project includes an in-person measured survey at your property in Tunbridge Wells. We typically combine the measured survey with an initial brief discussion on site, then return for pre-submission checks if needed. For projects that require pre-application meetings at Tunbridge Wells Borough Council, we attend on your behalf and include the call or meeting in the fee.
Yes. While our office is in London, our MCIAT chartered architectural technologists regularly submit to councils across the M25 commuter belt, including Tunbridge Wells Borough Council. We use the Planning Portal for submissions, so the process is identical regardless of which local planning authority handles your application. We research each council's Local Plan, design guides, and recent decision history before preparing your drawings so that the scheme aligns with their current approach.
The statutory target for a householder planning application is 8 weeks from validation. Tunbridge Wells Borough Council generally meets this target for straightforward applications, although conservation area or listed building consents can take longer. Pre-application advice typically takes 4–6 weeks. From initial instruction to final decision, expect 10–16 weeks for a typical residential project in Tunbridge Wells.
