Scottish Borders
Knocking through to a rear extension in the Scottish Borders
Steel beams, padstones and props to open the back of the house safely. Rear extensions in the Scottish Borders: we cover 5 towns including Hawick, Galashiels and Peebles, with design, approvals and the build under one contract.

Older houses in the Scottish Borders often have solid brick back walls carrying a lot of weight, so the steel design comes early. Post-war semis and terraces are common around the Scottish Borders, and many have room for a single-storey rear extension within Class 1A limits.
What does it cost in the Scottish Borders?
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 the Scottish Borders?
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.
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.
