What is a structural alteration?
A structural alteration changes how a house carries its loads, most often by removing a load-bearing wall and replacing it with a steel beam. It is how kitchens and dining rooms become open-plan, and how extensions are joined to the original house.
How much does a structural alteration cost in the Scottish Borders?
In the Scottish Borders, a structural alteration typically costs £4,250–£9,250 for a typical knock-through with steel beam, including VAT at 20% (standard rate). Building costs in Scotland are close to the UK average, so the figures for the Scottish Borders are close to our national guide. Design, structural calculations and council fees are extra.

Do you need planning permission for a structural alteration in the Scottish Borders?
Here is how the rules work for a structural alteration in Scotland. In Scotland removing a load-bearing wall needs a building warrant before work starts.
Scotland has no Party Wall Act. Work on shared walls is governed by your title deeds, the Tenements (Scotland) Act 2004 for flats, and common law, so we agree arrangements with neighbours in writing before work starts.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
Handled as part of most structural alterations:
- Written agreement with neighbours on shared walls
- Steel beam supply and installation on padstones
- Building control sign-off
- Structural engineer’s calculations and drawings
- Building control application
- Temporary propping
How long does it take?
The build itself usually takes 1 to 2 weeks on site for a typical knock-through. Design and approvals come first and typically take 6 to 12 weeks, depending on the approval route.
Building in the Scottish Borders
In Scotland, bungalows and one-and-a-half-storey homes are common, so dormer conversions are a popular way to add bedrooms.
Towns we cover in the Scottish Borders include Hawick, Galashiels, Peebles, Kelso and Selkirk.
