Covering Swanage
Swanage sits 22 miles east of Dorchester, with Poole 7 miles to the north and Bournemouth 8 miles to the north-east.
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 Swanage?
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
- Steel frame or goalpost for the corner opening
- Pitched, flat or glazed roof with rooflights
What will a wraparound extension cost?
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 |
How is a wraparound extension approved in Swanage?
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
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 Swanage 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.
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.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
