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.

Do you need permission for a structural alteration in Corsham?

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. It does need building regulations approval because it affects the structure.

What should I think about before starting?

Removing walls can affect the fire escape route on open-plan ground floors in three-storey houses.
Pipes and cables in the wall need rerouting first.

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.
We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

Your questions answered

How do I know if a wall is load-bearing?

We check on site and confirm with the structural engineer.
