Homes in Mid 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.
- Structural engineer’s design and calculations
- Temporary works and propping
- Making good floors, walls and ceilings

How is a structural alteration approved in Tonypandy?

Internal work like this does not usually need planning permission in Wales unless the building is listed.
What can affect a structural alteration?
- Removing walls can affect the fire escape route on open-plan ground floors in three-storey houses.
- Pipes and cables in the wall need rerouting first.
