What load-bearing wall removal involves in Cornwall
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.
We carry out load-bearing wall removal throughout Cornwall, for homeowners, landlords and builders who need the structural part done properly. Coverage takes in St Austell, Redruth and Falmouth and everywhere in between. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.
Things to plan for
- 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.
- Temporary works matter as much as the beam. Props, spreaders and needles carry the house while the wall is out, and they are positioned so the floor below can take them too.
- 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.
- 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.
- Cables, pipes, radiators and sometimes gas runs pass through internal walls. These are traced at the survey so they can be rerouted by the right trade before or during the work, not discovered halfway through.
What happens, step by step
Survey in Cornwall
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.
How much should I budget in Cornwall?
As a guide, budget £2,050–£5,150 including VAT for load-bearing wall removal with steel beam in Cornwall, based on published UK cost guides adjusted for prices in the South West (+3%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Load-bearing wall removal with steel beam | £2,050–£5,150 | Typical internal wall up to about 4 m: calculations, building control, propping, steel, padstones, fitting, fire protection and making good |
| Structural calculations for a beam | £260–£770 | Site measure or photos, beam and padstone design and calculations for building control |
| Building control fees | £260–£670 | Building notice or full plans fee and inspections; varies by council or approver |
| Kitchen-diner knock-through | £2,600–£6,200 | Internal structural wall between kitchen and dining room, steel beam, approvals and making good (kitchen fitting extra) |
Figures include our approximate regional adjustment for prices in the South West (+3%) and are rounded. How these figures are worked out.
Approvals in Cornwall
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.
Questions about load-bearing wall removal in Cornwall
What happens at the survey visit in Cornwall?
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.
Which towns in Cornwall do you cover?
We cover towns including Redruth, Falmouth, St Austell and Truro, plus the villages and smaller towns around them.
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.
Will the beam show once the job is finished?
It depends on the design. Most beams sit just below the ceiling and are boxed in with plasterboard, leaving a small step. A beam can be set up into the floor void for a flat ceiling, which takes more work, or left exposed and painted where you want an industrial look.
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 does the price include?
Our written quote is itemised, so you can see the calculations, building control fees, propping, steel, padstones, labour, fire protection and making good set out line by line. The price is fixed in writing once the layout and scope are agreed.
