What is a structural alteration?

Steel beam installed across a wide opening with props in place during a knock-through

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.

Do you need planning permission for a structural alteration in Stirling and Falkirk?

The approval route for Stirling and Falkirk is set by planning law 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

What we take care of:

  • Making good, plastering and flooring repairs
  • Building control application
  • Written agreement with neighbours on shared walls

  • Steel beam supply and installation on padstones
  • Building control sign-off

How long does it take?

Build time is typically 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.
