Planning load-bearing wall removal in Caerphilly

Load-bearing wall removal means taking out a wall that holds up floors, roof loads or walls above it, and replacing that support with a steel beam sized by a structural engineer. The beam sits on padstones at each end, the weight above is held on temporary props while the wall comes out, and building control inspects the finished work.

Across Caerphilly, load-bearing wall removal usually comes up when people want more light, a better layout or a way through to a new extension. We can survey in places such as Blackwood, Risca and Gelligaer and the villages around them. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.

Things to plan for

  • The finished opening should be signed off with a completion certificate from building control. Keep it with your house documents, as solicitors ask for it when the property is sold.
  • Most single-wall removals in a typical house take two to five working days on site for the structural part. Plastering, drying out and decorating follow on, and building control visits fit around those stages.
  • Each end of the beam needs a solid bearing. Padstones spread the point load into the masonry below, and if the wall underneath is weak the engineer may call for a steel column or a new pad foundation instead.
  • Building control is needed because removing a structural wall is controlled building work. Doing it without approval can cause problems when you come to sell, and putting it right afterwards costs far more than doing it properly first time.
  • A beam can sit below the ceiling with a small boxed downstand or be set up into the floor void so the ceiling runs flat. A flush beam usually needs more work to the joists and costs more.

What happens, step by step

  1. Free visit

    A short visit to Caerphilly to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit the application or notice to Caerphilly County Borough Council under the Building Regulations as they apply in Wales, before work starts.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in Caerphilly

Removing a load-bearing wall in Wales needs approval under the Welsh building regulations before work starts. For Caerphilly the application goes to Caerphilly County Borough Council or a registered building control approver, with the engineer's calculations, and a completion certificate follows the final inspection.

Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Load-bearing wall removal in Caerphilly: your questions

Do you cover Caerphilly for load-bearing wall removal?

Yes. We carry out load-bearing wall removal in Caerphilly. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Do I need a party wall agreement for load-bearing wall removal in Caerphilly?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.

How do I know if my wall is load-bearing?

Clues include floor joists that run across the top of the wall, a wall directly above it upstairs, and a wall that is solid brick or block rather than a hollow stud partition. None of these is proof on its own. A structural engineer checks on site and confirms it before any work is planned.

Do I need planning permission to remove an internal wall?

Usually not, because internal alterations to a house are not normally development needing planning permission. Listed buildings are different and need listed building consent, and flats normally need the freeholder's or landlord's written consent.

Is a steel beam better than a concrete lintel?

For short openings in some walls a lintel can be enough, but wide openings carrying floors or walls above normally need steel. The engineer chooses whatever does the job properly. Steel is common because it carries a lot of load for its depth.

How long does it take to remove a load-bearing wall?

For a typical house the structural part usually takes two to five working days: propping, taking the wall out, fitting the steel and packing it tight. Plastering and decorating follow once building control has inspected the steel.

What happens at the survey visit in Caerphilly?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
