What do you get with 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.
- Structural engineer’s design and calculations
- Steel beam installation on padstones
- Fire protection and plaster encasement

Do you need permission for a structural alteration in Penarth?
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 Penarth homeowners check first?
- The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
- Pipes and cables in the wall need rerouting first.
What happens after I enquire?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
