Structural alterations in St Austell

Because Cornwall covers a wide area, we confirm availability after the first call and include any travel costs in the written quote rather than adding them later.

Homes in the South West

The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.

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.

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?

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.

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.

Often it can be set within the floor depth, avoiding a downstand. The engineer confirms what is possible.
