Merseyside
Knocking through to a rear extension in Merseyside
Steel beams, padstones and props to open the back of the house safely. Rear extensions in Merseyside: we cover 41 towns including Liverpool, St Helens and Southport, with design, approvals and the build under one contract.
Older houses in Merseyside often have solid brick back walls carrying a lot of weight, so the steel design comes early. Stone and brick terraces are common around Merseyside. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
What does it cost in Merseyside?
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 Merseyside?
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 Merseyside?
We cover 41 towns and districts in Merseyside, including Liverpool, St Helens and Southport.
