What is 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
How much does a structural alteration cost in Pwllheli?

How is a structural alteration approved in Pwllheli?
Welsh projects need planning clearance from the council under Welsh rules, building regulations approval under the Welsh approved documents, and party wall notices where the work affects a neighbour’s wall or foundations.
Internal work like this does not usually need planning permission in Wales unless the building is listed.
What can change the price or programme?
- 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.

Your questions answered
Do I need building regulations approval to remove a wall?
Yes, for any load-bearing wall. Non-structural partitions usually do not need approval.
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.
