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 North Yorkshire?
In North Yorkshire, a structural alteration typically costs £4,250–£8,750 for a typical knock-through with steel beam, including VAT at 20% (standard rate). Building costs in Yorkshire and the Humber run about 7% below the UK average, and the figures for North Yorkshire are adjusted to reflect that. Design, structural calculations and council fees are extra.

The biggest cost drivers are:
- Floor and ceiling repairs
- Flush or downstand beam
- What sits above the wall
- Party wall involvement
Your exact price depends on the survey and drawings. The guide price tool gives a quick range in the meantime.
Do you need planning permission for a structural alteration in North Yorkshire?
Here is how the rules work for a structural alteration 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.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
From survey to sign-off, the job normally involves:
- Making good, plastering and flooring repairs
- Building control application
- Party wall notices where needed
- Fire protection to the steel
- Building control sign-off
- Structural engineer’s calculations and drawings
How long does it take?
Expect 1 to 2 weeks on site for a typical knock-through. Design and approvals come first and typically take 6 to 12 weeks, depending on the approval route.
