Covering Helston
Our coverage around Helston (TR13) also includes Redruth, Falmouth and Truro.
Because Cornwall covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.
Homes in the South West
Homes in the South West range from coastal and rural properties in stone and slate to city terraces and modern estates, so extensions are designed to match the local materials.
What is included in a wraparound extension in Helston?
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.
- Steel frame or goalpost for the corner opening
- Pitched, flat or glazed roof with rooflights
- Glazing, insulation, plastering and electrics
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 |
What approvals does a wraparound extension need in England?
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 Helston homeowners check first?
- 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.
How does the project run?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- 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.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Wraparound extensions: common questions
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.
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.
