Covering Chippenham
Chippenham sits 16 miles south-west of Swindon, with Corsham 3 miles to the south-west and Calne 5 miles to the east.
Homes in the South West
In the South West, matching local stone, render or slate is often the main design question, and conservation areas and listed buildings are common in historic towns.
What is a loft conversion?
We start with the head height. You need roughly 2.2 m or more from the top of the ceiling joists to the underside of the ridge for a conversion to work without raising the roof. From there we design the staircase position, the type of conversion and the en-suite, and manage the whole build including fire safety and building control.
- New floor joists, steels and staircase
- Dormer or rooflights, insulation and plasterboard
- En-suite, electrics, heating and fire safety upgrades
How much does a loft conversion cost in Chippenham?
What loft conversions typically cost. These are guide ranges; the written quote for your house replaces them.
| Loft conversions | Guide price incl. VAT |
|---|---|
| Rooflight conversion | £30,000 to £45,000 |
| Dormer conversion | £50,000 to £90,000 |
| Hip-to-gable with dormer | £60,000 to £95,000 |
| Mansard conversion | £65,000 to £110,000 |
Do you need permission for a loft conversion in Chippenham?
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 many loft conversions are permitted development: the extra roof volume must stay within 40 m³ on a terraced house or 50 m³ on a semi or detached house, nothing can sit higher than the existing ridge, no dormer can face a road on the main elevation, and side windows must be obscure-glazed and non-opening below 1.7 m. Houses in conservation areas, National Parks and National Landscapes cannot use these roof-extension rights, so dormers there need planning permission (a rooflight-only conversion can still be permitted development), and flats always need permission.
What can affect a loft conversion?
- Head height under the ridge decides whether a conversion is practical.
- Fire safety rules can mean new fire doors on the floors below.

- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- 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.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Your questions answered
Does a loft conversion need planning permission?
In England many are permitted development, within 40 m³ of extra volume on a terrace or 50 m³ on a semi or detached house. Conservation areas and flats need permission.
Do I need fire doors?
Often yes. Building regulations require a protected escape route from the new floor, which usually means fire doors on to the stairs and linked smoke alarms.
