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.

We come out to measure up at no cost, explain the choices in plain terms and send a written quote.

Building in Penarth
Cardiff has large areas of bay-fronted Victorian and Edwardian terraces in districts such as Roath, Canton and Cathays, plus interwar suburbs, post-war estates and modern flats around Cardiff Bay. Penarth has Victorian villas, Barry mixes terraces with newer estates, and Vale of Glamorgan villages are often built of local limestone.
Mild but wet, with coastal exposure along the Severn estuary and Bristol Channel affecting render, roofline and windows.
With that background in mind, here is how we typically handle removing a wall for homes in Penarth, from the first visit to the finished result.
Do you need permission in Penarth?
Planning law differs across the UK. For a home in Penarth, it is the Wales rules below that count, and we check them with the council ahead of any 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.
From survey to handover
Survey and measure
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Quote in writing
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for removing a wall.
Plan and prepare
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for removing a wall are in place before the first day on site.
The work itself
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.

Questions about removing a wall in Penarth
How do I know if a wall is load-bearing?
A wall is load-bearing if it carries weight from above, such as floor joists, another wall, the roof or a chimney. Clues include joists running across the wall rather than alongside it, and walls lined up with walls on the floor above. Brick or block walls are often structural but not always. We check from above and below during the survey, and an engineer confirms the design.
Do I need building regulations approval to remove a wall?
Removing a load-bearing wall needs building regulations approval anywhere in the UK, and in Scotland a building warrant. A structural engineer calculates the beam and supports, and building control inspects the work. Removing a non-structural wall may still need approval if it affects fire escape routes, such as opening a hallway into a living room. We handle the applications and inspections.
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.
How long will removing a wall take?
On a typical home, allow 1–3 weeks including making good. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
