Covering Barry
Our coverage around Barry (CF62) also includes Penarth (5 miles to the north-east) and Cardiff.
Homes in South Glamorgan
Welsh homes include long terraces built into hillsides, stone cottages and modern estates, and sloping sites often shape how and where an extension can go.
What goes into a structural alteration?
Structural alterations change the load-bearing parts of a house, most often removing a wall between two rooms and putting in a steel beam to create an open-plan layout. The work needs a structural engineer’s design and building regulations approval.
- Planning and building regulations checks under Welsh rules
- Structural engineer’s design and calculations
- Building control application and inspections
What will a structural alteration cost?
Guide prices for structural alterations, including VAT where it applies. Your fixed price is confirmed in writing after the survey.

| Chimney breast removal with support | £1,800 to £4,500 |
| Multiple walls or full open-plan remodel | £8,000 to £20,000 |
Do you need permission for a structural alteration in Barry?
Planning decisions in Wales are made by the local council, using permitted development rules set by the Welsh Government rather than England’s. Building regulations in Wales have their own approved documents, and the Party Wall etc. Act 1996 applies to work on shared walls and boundaries.
Internal work like this does not usually need planning permission in Wales unless the building is listed.
What should I think about before starting?
- The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
- Removing walls can affect the fire escape route on open-plan ground floors in three-storey houses.
From first call to completion
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
What people ask before starting
How do I know if a wall is load-bearing?
We check on site and confirm with the structural engineer.
Can the steel be hidden in the ceiling?
Often it can be set within the floor depth, avoiding a downstand. The engineer confirms what is possible.
Can you visit a house in Barry to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
