Covering Chippenham
Our coverage around Chippenham (SN15) also includes Corsham, Calne and Devizes.
Homes in the South West
The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.
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.
- Party wall process with both neighbours if needed
- Steel frame or goalpost for the corner opening
- Optional kitchen supply and installation
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 Chippenham?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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 can affect a wraparound extension?
- The corner steel connection is the critical detail and is designed by a structural engineer.
- Both neighbours may need party wall notices.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- 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.
