Structural alterations in Southampton

Covering Southampton

Alongside Southampton, we also cover Totton (4 miles to the west), Eastleigh and Fareham.

Homes in the South East

Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.

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.

How is a structural alteration approved in Southampton?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

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 affect a structural alteration?

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.
