Bungalow and upward extensions in Cambridgeshire

Covering Cambridgeshire

Our bungalow and upward extensions service in Cambridgeshire covers Peterborough, Cambridge, Wisbech and St Neots and more.

Homes in the East of England

The East of England has a large stock of post-war and modern estate housing alongside period homes in market towns, which makes garage conversions, single-storey extensions and loft conversions popular.

What does an upward extension involve?

An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.

What approvals does an upward extension 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.

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 should I think about before starting?

Some bungalow foundations need strengthening before a storey can be added.
The house is exposed while the roof is off, so the sequence is planned tightly.

Bungalow and upward extensions: common questions

Is an upward extension permitted development?

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

Do we need to move out?

Often for part of the job, while the roof is off and the new floor is formed. We plan this with you.

Can you visit a house in Cambridgeshire 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.
