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.

In Stornoway, a structural alteration typically costs £4,250–£9,250 for a typical knock-through with steel beam, including VAT at 20% (standard rate).

A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.

Do you need planning permission for a structural alteration in Stornoway?

The approval route for Stornoway 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.

We check this for your address before design work starts, so there are no surprises later.

What we handle

On a typical structural alteration we handle:

  • Temporary propping
  • Building control application

  • Structural engineer’s calculations and drawings
  • Building control sign-off
  • Steel beam supply and installation on padstones

How long does it take?

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