What is a structural alteration?

Steel beam installed across a wide opening with props in place during a knock-through

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 Radcliffe?

In Radcliffe, a structural alteration typically costs £4,250–£9,000 for a typical knock-through with steel beam, including VAT at 20% (standard rate). That range is adjusted for the North West, where domestic building work typically costs around 6% below the national average. Design, structural calculations and council fees are extra.

Do you need planning permission for a structural alteration in Radcliffe?

Before anything is built in Radcliffe, we confirm which approvals apply 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.

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.

We check this for your address before design work starts, so there are no surprises later.

What we handle

From survey to sign-off, the job normally involves:

  • Building control application
  • Fire protection to the steel
  • Structural engineer’s calculations and drawings
  • Building control sign-off
  • Party wall notices where needed
  • Steel beam supply and installation on padstones

How long does it take?

Allow 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.

Questions about structural alterations in Radcliffe

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.

Do I need building regulations approval?

Yes. Removing a load-bearing wall is building work that needs approval, with calculations for the beam.

How long does a structural alteration take in Radcliffe?

Typically 1 to 2 weeks on site for a typical knock-through. Design and approvals beforehand usually take 6 to 12 weeks.

Can the beam be hidden?

Often, by setting it within the ceiling depth. It depends on the joists and span.
