County Durham
Knocking through to a rear extension in County Durham
Steel beams, padstones and props to open the back of the house safely. Across County Durham we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Darlington, Hartlepool and Stockton-on-Tees.
Older houses in County Durham often have solid brick back walls carrying a lot of weight, so the steel design comes early. Brick terraces, colliery houses and post-war semis make up much of County Durham. Former mining areas often need a coal mining risk check before foundations are designed.
What does it cost in County Durham?
As a guide, £3,500–£9,000 including VAT. These are guide ranges; the written quote after the survey is the figure that counts.
What approvals does it need in County Durham?
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.
