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 Tyne and Wear?

In Tyne and Wear, a structural alteration typically costs £4,000–£8,500 for a typical knock-through with steel beam, including VAT at 20% (standard rate). We start from a UK-wide guide and adjust it for the North East, where labour and materials are typically about 10% below average. Design, structural calculations and council fees are extra.

  • What sits above the wall

A guide range is only a starting point: the guide price tool gives an instant figure for your size, and a free survey turns it into a fixed quote.

Do you need planning permission for a structural alteration in Tyne and Wear?

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.

Our first visit includes a check of your planning history, so you know the route before paying for drawings.

What we handle

Handled as part of most structural alterations:

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

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.
