Covering New Malden
New Malden sits 9 miles south-west of London, with Surbiton 2 miles to the west and Morden 3 miles to the east.
Homes in London
Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.
What do you get with a structural alteration?
We arrange the structural calculations, support the floors and roof above with temporary props while the wall comes out, install the steel on padstones, then encase it for fire protection and make good. Chimney breast removals and new openings in external walls follow the same process.
- Structural engineer’s design and calculations
- Temporary works and propping
- Steel beam installation on padstones

Planning and building rules in New Malden
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 can affect a structural alteration?
- Shared chimney breasts and walls can involve the Party Wall Act.
- Pipes and cables in the wall need rerouting first.
What are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
