Structural alterations in Horley

Covering Horley

We work in Horley (RH6) and the places around it, including Crawley, Redhill and Reigate.

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 do you get with 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.

How much does a structural alteration cost in Horley?

Indicative costs for structural alterations. London and the South East usually sit towards the top of each range.

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

What approvals does a structural alteration need in England?

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.
Removing walls can affect the fire escape route on open-plan ground floors in three-storey houses.
