Bungalow and upward extensions in Lancashire

Covering Lancashire

Our bungalow and upward extensions service in Lancashire covers Preston, Burnley, Blackburn and Blackpool and more.

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 goes into an upward extension?

The first question is whether the existing walls and foundations can carry the extra load, so we start with a structural survey. Then we design either a full first floor or a raised roof with dormers, handle planning or prior approval, and build the new storey while protecting the floor below.

Do you need permission for an upward extension in Lancashire?

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.

In England, Class AA permitted development allows an extra storey on many detached and semi-detached houses built between July 1948 and October 2018, subject to a prior approval application covering design, neighbours’ amenity and other matters. Houses in conservation areas and other protected land need full planning permission, as do most chalet conversions with front dormers.

What can affect an upward extension?

Some bungalow foundations need strengthening before a storey can be added.
Neighbours’ light and privacy are the main planning tests.

What are the steps?

We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
Design and fixed price. You get drawings and a written price for the agreed specification before anything is ordered.
Construction and completion. One site lead co-ordinates every trade through to the building control certificate.

Questions about an upward extension in Lancashire

In England, Class AA allows it on many post-1948 houses through a prior approval application. Elsewhere planning permission is needed.

Can you visit a house in Lancashire 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.
