Covering East Sussex
Our wraparound extensions service in East Sussex covers Brighton, Eastbourne, Hastings and Hove and more.
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 goes into a wraparound extension?
Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.
- Design, planning drawings and structural calculations
- Party wall process with both neighbours if needed
- Steel frame or goalpost for the corner opening
How much should I budget for a wraparound extension?
Typical ranges for wraparound extensions. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Wraparound extensions | Guide price incl. VAT |
|---|---|
| Standard specification | £3,400 to £3,800 per m² |
| Good specification | £3,800 to £4,250 per m² |
| High specification | £4,250 to £4,700 per m² |
Do you need permission for a wraparound extension in East Sussex?
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. Most need householder planning permission, which usually takes around eight weeks once validated.
What can change the price or programme?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- An open-plan space this size needs a heating plan, often underfloor heating.
From first call to completion
- 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.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
