Covering Ewell
We work in Ewell (KT17) and the places around it, including Epsom, Sutton and Banstead.
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?
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.
- Pitched, flat or glazed roof with rooflights
- Glazing, insulation, plastering and electrics
- Optional kitchen supply and installation
What will a wraparound extension cost?
Use these ranges to budget for wraparound extensions; the survey turns them into a fixed price for the agreed specification.
| 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 Ewell?
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 can change the price or programme?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- Both neighbours may need party wall notices.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Wraparound extensions: common questions
How much does a wraparound extension cost?
Typically £3,400 to £4,700 per square metre including VAT. Many come in between £85,000 and £120,000 before the kitchen.
Does a wraparound need planning permission?
Usually yes. In England it combines a side and rear extension, which takes it outside permitted development in most cases.
Who deals with the council for a project in Ewell?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
