Glasgow and the Clyde
Knocking through to a rear extension in Glasgow and the Clyde
Steel beams, padstones and props to open the back of the house safely. Across Glasgow and the Clyde we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Glasgow, Paisley and Greenock.

Older houses in Glasgow and the Clyde often have solid brick back walls carrying a lot of weight, so the steel design comes early. Glasgow and the Clyde has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.
What does it cost in Glasgow and the Clyde?
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 Glasgow and the Clyde?
Scottish extensions are approved by building warrant, granted by the council's building standards team before work begins, with a completion certificate submitted when the work is finished.
Classes 1A and 1B do not apply in conservation areas, and listed buildings 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.

The wall itself usually comes out in a day or two, timed for when the extension is weathertight.
