Structural alterations in Portsmouth

Covering Portsmouth

Our coverage around Portsmouth (PO5) also includes Gosport (2 miles to the west) and Fareham.

Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

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.

What is the guide price for a structural alteration in Portsmouth?

Structural alterations	Guide price incl. VAT

How is a structural alteration approved in Portsmouth?

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.

What should Portsmouth homeowners check first?

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.
