Homes in London

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.

How is a structural alteration approved in Coulsdon?

English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.

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 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.
