London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.
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.
- Structural engineer’s design and calculations
- Temporary works and propping
- Fire protection and plaster encasement

Do you need permission for a structural alteration in Northolt?
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.
What should Northolt homeowners check first?
- 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.
