Knocking through to a rear extension in Lancashire
Steel beams, padstones and props to open the back of the house safely. We design and build rear extensions across Lancashire, from Preston and Burnley to Blackburn, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Older houses in Lancashire often have solid brick back walls carrying a lot of weight, so the steel design comes early. Lancashire has long runs of terraced houses with back yards and alleys, plus 1930s semis further out. Yard extensions on terraces are often single-storey and close to both boundaries.
What does it cost in Lancashire?
As a guide, £3,500–£9,000 including VAT. Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
What approvals does it need in Lancashire?
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.
Do you cover all of Lancashire?
We cover 28 towns and districts in Lancashire, including Preston, Burnley and Blackburn.
