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.

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

Approvals for a structural alteration in Hyde 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.

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

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

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

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.

Questions about structural alterations in Hyde

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.

What fire protection does a steel need?

Usually fire-rated plasterboard or intumescent paint, as building control requires.

How long does a structural alteration take in Hyde?

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.
