Knocking through to a rear extension in Essex
Steel beams, padstones and props to open the back of the house safely. We design and build rear extensions across Essex, from Southend-on-Sea and Basildon to Colchester, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Older houses in Essex often have solid brick back walls carrying a lot of weight, so the steel design comes early. Essex mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
What does it cost in Essex?
As a guide, £3,500–£9,000 including VAT. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
What approvals does it need in Essex?
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.
