Covering Streatham
Our coverage around Streatham (SW16) also includes Mitcham, Brixton and Wimbledon.
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 goes into 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.
- Building control application and inspections
- Steel beam installation on padstones
- Making good floors, walls and ceilings
How much should I budget for a structural alteration?
What structural alterations typically cost. These are guide ranges; the written quote for your house replaces them.
| 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 Streatham?
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 should I think about before starting?
- Shared chimney breasts and walls can involve the Party Wall Act.
- Pipes and cables in the wall need rerouting first.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- 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.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
Structural alterations: common questions
Do I need building regulations approval to remove a wall?
Yes, for any load-bearing wall. Non-structural partitions usually do not need approval.
Can the steel be hidden in the ceiling?
Often it can be set within the floor depth, avoiding a downstand. The engineer confirms what is possible.
Can you visit a house in Streatham to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
