Covering Chelsea
Our coverage around Chelsea (SW3, SW10) also includes Battersea, Fulham and Notting Hill.
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
- Fire protection and plaster encasement
What will a structural alteration cost?
Indicative costs for structural alterations. London and the South East usually sit towards the top of each range.
| 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 |
How is a structural alteration approved in Chelsea?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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 can affect a structural alteration?
- The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
- Pipes and cables in the wall need rerouting first.
How does the project run?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
