Wall removal is taking out an internal wall to open up rooms; where the wall is load-bearing, a steel beam sized by a structural engineer is installed on padstones to carry the weight above, with the work approved by building control.
If you live in Caerphilly and are weighing up removing a wall, the starting point is a visit to measure up and talk through what you want, which costs nothing. We cover homes across CF83, and a typical project of this kind in Wales lands somewhere in the £2,800–£7,400 bracket, including VAT. The exact figure depends on size, access and the finish you choose.

Building in Caerphilly
The Rhondda, Cynon and Merthyr valleys are lined with stone terraces built for mining families, stepped along steep hillsides. Pontypridd, Caerphilly and Merthyr Tydfil have Victorian centres, and Bridgend has grown with large modern estates alongside interwar and post-war housing.
The valleys get heavy rainfall and steep, sloping sites are common, so drainage, retaining walls and render specification matter.
If your house in Caerphilly fits one of these patterns, it helps us anticipate what removing a wall will involve, though we always confirm the details on site.
Planning and building rules in Caerphilly
Caerphilly is in Wales, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
Removing an internal wall does not need planning permission in Wales unless the building is listed.
Load-bearing walls need Building Regulations approval and structural calculations; the Party Wall etc. Act 1996 applies to shared walls.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How does the job run?
A visit to your home
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for removing a wall so the price reflects your home.
Your fixed price
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Booking the work
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Caerphilly property.
On site to finish
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
How we work
Common questions
What is a steel beam and why is it needed?
A steel beam, often called an RSJ, is a strong steel section installed where a load-bearing wall used to be, so the weight above is carried across the opening to the walls at each end. It sits on padstones that spread the load. The size depends on the span and the load, which a structural engineer calculates. The beam is then boxed in or plastered.
Can I have a beam that does not show?
A flush or hidden beam sits within the depth of the ceiling so there is no visible downstand, giving a clean, open look. It is possible where the floor joists can be connected into the side of the beam, which takes more steel and labour. It costs more than a standard beam below the ceiling. The engineer confirms whether it suits your house.
Do I need planning permission in Caerphilly?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Caerphilly is in Wales, so Wales's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
How disruptive is removing a wall?
Removing a wall is dusty and noisy, but the most disruptive part is short, usually one to three days for propping, demolition and installing the steel. We seal doorways with dust screens, protect floors and keep a safe route through the house. Making good, plastering and floor repairs follow over the next week or two. Most people stay at home throughout.
Can I stay at home during the work?
In most cases, yes. Most people can live at home throughout, and we plan the work to keep disruption down by protecting floors, agreeing working hours and keeping access routes clear. Bigger jobs affecting kitchens, bathrooms or heating may mean a short spell with reduced facilities, and we talk this through with you at the survey.
