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 Galashiels?

Whether you need planning permission depends on your house and its location 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.

Our first visit includes a check of your planning history, so you know the route before paying for drawings.

What we handle

Handled as part of most structural alterations:

  • Steel beam supply and installation on padstones
  • Structural engineer’s calculations and drawings
  • Written agreement with neighbours on shared walls
  • Temporary propping
  • Building control application
  • Building control sign-off

How long does it take?

Build time is typically 1 to 2 weeks on site for a typical knock-through. Allow time beforehand for drawings and approvals, usually 6 to 12 weeks.
