Knocking through to a rear extension in Devon
Steel beams, padstones and props to open the back of the house safely. Rear extensions in Devon: we cover 21 towns including Plymouth, Exeter and Paignton, with design, approvals and the build under one contract.
Older houses in Devon often have solid brick back walls carrying a lot of weight, so the steel design comes early. Stone-built and rendered houses are common around Devon, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
What does it cost in Devon?
As a guide, £3,500–£9,000 including VAT. Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
What approvals does it need in Devon?
Planning and Building Regulations are separate in England: even a permitted development extension is inspected for foundations, drainage, structure, insulation, fire safety and ventilation, through the council or a registered building control approver, ending with a completion certificate.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.

FAQ
Questions people ask
Can the whole back wall come out?
Often, with a beam across the full width or a goalpost frame. Some walls need a short pier left at the ends.
Do I need building control for a beam?
Yes. The calculations and the installed steel are checked.
How long does it take?
The wall itself usually comes out in a day or two, timed for when the extension is weathertight.
Do you cover all of Devon?
We cover 21 towns and districts in Devon, including Plymouth, Exeter and Paignton.
