Structural alterations in Greenwich

Covering Greenwich

Greenwich is about 5 miles east of London. We also cover Blackheath (1 miles to the south-east), Catford and Peckham.

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.

What approvals does a structural alteration need in England?

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 change the price or programme?

Shared chimney breasts and walls can involve the Party Wall Act.
Pipes and cables in the wall need rerouting first.
