Bungalow and upward extensions in Basingstoke

Covering Basingstoke

Basingstoke is about 28 miles north-east of Southampton. We also cover Fleet (11 miles to the east), Thatcham and Farnham.

Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

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 Basingstoke?

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.

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.
