Bungalow and upward extensions in Stockport

Covering Stockport

Stockport is about 6 miles south-east of Manchester. We also cover Cheadle Hulme (3 miles to the south-west), Denton and Hyde.

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 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 can affect an upward extension?

Some bungalow foundations need strengthening before a storey can be added.
The staircase takes space from the ground floor plan.

Your questions answered

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.
