Covering Finchley
Alongside Finchley, we also cover Muswell Hill, Cricklewood (3 miles to the south) and Kilburn.
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 does a structural alteration involve?
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
How much should I budget for a structural alteration?
Use these ranges to budget for structural alterations; the survey turns them into a fixed price for the agreed specification.
| Structural alterations | Guide price incl. VAT |
|---|---|
| Single load-bearing wall removal with steel | £3,000 to £7,500 |
| Chimney breast removal with support | £1,800 to £4,500 |
| Multiple walls or full open-plan remodel | £8,000 to £20,000 |
Do you need permission for a structural alteration in Finchley?
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.
- The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
What happens after I enquire?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- 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.
Your questions answered
Do I need building regulations approval to remove a wall?
Yes, for any load-bearing wall. Non-structural partitions usually do not need approval.
How do I know if a wall is load-bearing?
We check on site and confirm with the structural engineer.
Who deals with the council for a project in Finchley?
We do. We prepare the drawings, submit planning or permitted development paperwork if needed, and arrange building control inspections.
