Knocking through to a rear extension in Surrey
Steel beams, padstones and props to open the back of the house safely. Rear extensions in Surrey: we cover 35 towns including Woking, Guildford and Esher, with design, approvals and the build under one contract.
Older houses in Surrey often have solid brick back walls carrying a lot of weight, so the steel design comes early. Commuter semis and detached houses make up much of Surrey, and longer gardens make England's prior approval route for deeper rear extensions worth considering.
What does it cost in Surrey?
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 Surrey?
Every rear extension in England needs Building Regulations approval, whether or not planning is needed. You can use the council's building control service or a registered building control approver, by full plans (checked before work, usually within five weeks) or a building notice, and you get a completion certificate at the end.
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.

We cover 35 towns and districts in Surrey, including Woking, Guildford and Esher.
