Homes in the South West

Homes in the South West range from coastal and rural properties in stone and slate to city terraces and modern estates, so extensions are designed to match the local materials.

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.

Planning and building rules in Wiltshire

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 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.
