What does a structural alteration involve?

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.

Do you need permission for a structural alteration in Walton-on-Thames?

Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

Internal work like this does not usually need planning permission unless the house is listed or your permitted development rights have been removed. It does need building regulations approval because it affects the structure.

What can affect a structural alteration?

Shared chimney breasts and walls can involve the Party Wall Act.
The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
