Northamptonshire
Knocking through to a rear extension in Northamptonshire
Steel beams, padstones and props to open the back of the house safely. Across Northamptonshire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Northampton, Corby and Kettering.
Older houses in Northamptonshire often have solid brick back walls carrying a lot of weight, so the steel design comes early. Red-brick terraces and semis are typical of Northamptonshire. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.
What does it cost in Northamptonshire?
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 Northamptonshire?
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.
