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?

Structural alterations change the load-bearing parts of a house, most often removing a wall between two rooms and putting in a steel beam to create an open-plan layout. The work needs a structural engineer’s design and building regulations approval.

How much does a structural alteration cost in Falmouth?

Typical ranges for structural alterations. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

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 Falmouth?

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 can change the price or programme?

The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
Removing walls can affect the fire escape route on open-plan ground floors in three-storey houses.
