Homes in London

Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.

What is included in a structural alteration in Purley?

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 Purley?

Structural alterations	Guide price incl. VAT

How is a structural alteration approved in Purley?

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.

What should Purley 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.

What people ask before starting

How long does it take?

The structural work is usually done in a few days, with one to three weeks including making good.

Can the steel be hidden in the ceiling?

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

Can you visit a house in Purley to quote?

Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
