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 Stirling?
In Stirling, 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 Stirling are close to our national guide. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A typical knock-through with steel beam | £4,250–£9,250 |

The biggest cost drivers are:
- What sits above the wall
- Floor and ceiling repairs
- Moving radiators, sockets and pipes
- Span of the opening

Do you need planning permission for a structural alteration in Stirling?
Before anything is built in Stirling, we confirm which approvals apply in Scotland. In Scotland removing a load-bearing wall needs a building warrant before work starts.
In Scotland a building warrant is needed before work starts on most extensions, loft conversions and conversions. It is issued by the council’s building standards service. When the work is finished, a completion certificate is submitted and accepted by the council after inspection.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
What we handle
What we take care of:
- Building control sign-off

- Temporary propping
- Making good, plastering and flooring repairs
- Structural engineer’s calculations and drawings
- Written agreement with neighbours on shared walls
How long does it take?
Expect 1 to 2 weeks on site for a typical knock-through. Allow time beforehand for drawings and approvals, usually 6 to 12 weeks.

Questions about structural alterations in Stirling
Do I need planning permission for a structural alteration in Stirling?
In Scotland removing a load-bearing wall needs a building warrant before work starts.
How do I know if a wall is load-bearing?
Only a survey can confirm it. Walls that carry floor joists, roof loads or walls above are load-bearing. We check on site and the engineer confirms.
What fire protection does a steel need?
Usually fire-rated plasterboard or intumescent paint, as building control requires.
Can the beam be hidden?
Often, by setting it within the ceiling depth. It depends on the joists and span.
