Covering Tonbridge
Our coverage around Tonbridge (TN9) also includes Tunbridge Wells (4 miles to the south) and Sevenoaks.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What do you get with a wraparound extension?
A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.
- Design, planning drawings and structural calculations
- Glazing, insulation, plastering and electrics
- Optional kitchen supply and installation

How is a wraparound extension approved in Tonbridge?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
In England a wraparound extension is treated as one extension, and because it covers both the side and the rear it does not normally fit within permitted development.
What should I think about before starting?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- Roof water from an L-shape needs careful falls and outlets.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Free site visit. We measure up, look at access, drains and the structure, and talk through options and budget.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Questions about a wraparound extension in Tonbridge
How long does a wraparound take?
Around 12 to 18 weeks on site after approvals.
Can we keep part of the kitchen working?
Often, by sequencing the work so the old back wall comes out last. We agree a plan with you before starting.
Can you visit a house in Tonbridge to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
