Pitched and lean-to roof rear extensions in Wiltshire
Lean-to, gable and hipped roofs that give a vaulted ceiling. Across Wiltshire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Swindon, Salisbury and Trowbridge.
Pitched roofs suit the cottages and slate-roofed houses in parts of Wiltshire. Stone-built and rendered houses are common around Wiltshire, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
How much does a pitched-roof rear extension cost in Wiltshire?
Guide prices for a pitched-roof rear extension in Wiltshire start from our South West England rate of £2,080–£3,380 per square metre, including VAT. South West prices run slightly above our West Midlands baseline; natural stone to match the house is the main variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £25,000–£40,500 |
| 4 m wide × 5 m deep (20 m²) | £41,500–£67,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission in Wiltshire?
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
Will a lean-to fit under my windows?
We check the sill heights at the survey; low windows usually mean a flat roof instead.
Are roof windows allowed?
Yes; they are the usual way to bring light into a pitched-roof extension.
Is a pitched roof more expensive?
Slightly, typically a few per cent more than a flat roof of the same area.
Do you cover all of Wiltshire?
We cover 14 towns and districts in Wiltshire, including Swindon, Salisbury and Trowbridge.
