Structural alterations in Darwen

Covering Darwen

Alongside Darwen, we also cover Blackburn, Accrington (6 miles to the north-east) and Chorley.

Homes in the North West

The North West has long rows of Victorian terraced houses in its towns and cities, alongside inter-war semis and post-war estates, so rear extensions, dormer lofts and kitchen extensions are common projects.

What is 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.

Planning and building rules in Darwen

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?

Shared chimney breasts and walls can involve the Party Wall Act.
Pipes and cables in the wall need rerouting first.
