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 Stourbridge?
In Stourbridge, 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 the West Midlands sit near the national average for this kind of work, and the range for Stourbridge reflects that. Design, structural calculations and council fees are extra.

Do you need planning permission for a structural alteration in Stourbridge?
Whether you need planning permission depends on your house and its location in 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.
Our first visit includes a check of your planning history, so you know the route before paying for drawings.
