Covering Winchester
Winchester sits 12 miles north of Southampton, with Eastleigh 7 miles to the south and Southampton 12 miles to the south.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
What is included in an upward extension in Winchester?
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
- New first-floor structure, walls and roof
- Full fit-out of the new rooms

Do you need permission for an upward extension in Winchester?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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 should Winchester homeowners check first?
- Some bungalow foundations need strengthening before a storey can be added.
- The staircase takes space from the ground floor plan.
