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.

Typical ranges for structural alterations. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

Multiple walls or full open-plan remodel	£8,000 to £20,000

Do you need permission for a structural alteration in West Glamorgan?

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. Building regulations approval is needed for the structural work.

What should I think about before starting?

Shared chimney breasts and walls can involve the Party Wall Act.
Pipes and cables in the wall need rerouting first.
