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 Highlands and Islands?
In the Highlands and Islands, a structural alteration typically costs £4,250–£9,250 for a typical knock-through with steel beam, including VAT at 20% (standard rate). Prices in Scotland sit near the national average for this kind of work, and the range for the Highlands and Islands reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a structural alteration in the Highlands and Islands?
Before anything is built in the Highlands and Islands, we confirm which approvals apply 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.
