Knocking through to a rear extension in Norfolk
Steel beams, padstones and props to open the back of the house safely. Across Norfolk we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Norwich, Great Yarmouth and King's Lynn.
Older houses in Norfolk often have solid brick back walls carrying a lot of weight, so the steel design comes early. Post-war semis and newer estates are typical of Norfolk, and many have room for a full-width extension. Shrinkable clay is common in the East of England, so foundations near trees and hedges are designed to NHBC-style depth guidance.
What does it cost in Norfolk?
As a guide, £3,500–£9,000 including VAT. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
What approvals does it need in Norfolk?
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 11 towns and districts in Norfolk, including Norwich, Great Yarmouth and King's Lynn.
