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 Sunderland?
In Sunderland, a structural alteration typically costs £4,000–£8,500 for a typical knock-through with steel beam, including VAT at 20% (standard rate). Prices across the North East are typically 10% below the UK average for this kind of work, which is reflected in the range for Sunderland. Design, structural calculations and council fees are extra.

Do you need planning permission for a structural alteration in Sunderland?
Approvals for a structural alteration in Sunderland follow the rules for England. In England removing a load-bearing wall does not need planning permission but does need building regulations approval with an engineer’s calculations. If the beam bears on a party wall, a party wall notice must be served.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
If the answer is not clear-cut, we can apply for formal confirmation before you commit to the build.
