Covering Bexley
We work in Bexley (DA15) and the places around it, including Welling, Dartford and Swanley.
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?
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
- Building control application and inspections
- Steel beam installation on padstones
What will a structural alteration cost?
Guide prices for structural alterations, including VAT where it applies. Your fixed price is confirmed in writing after the survey.
| 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 Bexley?
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 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 are the steps?
- 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.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
