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 Stanley?
In Stanley, a structural alteration typically costs £4,000–£8,500 for a typical knock-through with steel beam, including VAT at 20% (standard rate). The guide for Stanley reflects typical costs in the North East, roughly 10% below the UK-wide figure. Design, structural calculations and council fees are extra.
| Size or type | Guide range |
|---|---|
| A typical knock-through with steel beam | £4,000–£8,500 |
| Higher specification | £8,500–£10,500 |
What moves the price most:
- Moving radiators, sockets and pipes
- Party wall involvement
- What sits above the wall
- Flush or downstand beam
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 Stanley?
Approvals for a structural alteration in Stanley 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.
Where work involves a shared wall, building on the boundary, or digging foundations within 3 metres of a neighbour’s building and deeper than its foundations (or within 6 metres for deeper work), the Party Wall etc. Act 1996 applies and notices must be served before work starts.
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:
- Temporary propping
- Party wall notices where needed
- Fire protection to the steel
- Structural engineer’s calculations and drawings
- Making good, plastering and flooring repairs
- Building control sign-off
How long does it take?
Expect 1 to 2 weeks on site for a typical knock-through. Allow time beforehand for drawings and approvals, usually 6 to 12 weeks.

Questions about structural alterations in Stanley
What fire protection does a steel need?
Usually fire-rated plasterboard or intumescent paint, as building control requires.
How do I know if a wall is load-bearing?
Only a survey can confirm it. Walls that carry floor joists, roof loads or walls above are load-bearing. We check on site and the engineer confirms.
