Bungalow and upward extensions in Enfield

Covering Enfield

Alongside Enfield, we also cover Edmonton, Tottenham (3 miles to the south) and Wood Green.

Homes in London

London projects often mean working on period terraces with neighbours on both sides, tight access through the house and conservation area controls, so careful planning and party wall work matter as much as the build.

What is included in an upward extension in Enfield?

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.

Structural survey of walls and foundations
Design and planning or prior approval application
Roof removal and temporary weather protection

What approvals does an upward extension need in England?

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.

What should Enfield homeowners check first?

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