Eastleigh kitchen extensions, designed and built

Planning rules that apply in Eastleigh
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Common questions in Eastleigh
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Eastleigh, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How long does a kitchen extension take to build in Eastleigh?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Do I need building regulations approval in Eastleigh?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can you fit a kitchen I buy elsewhere?
Yes. We can fit it or work with your supplier’s fitters. We need the layout early so that drains, services and lighting are in the right place.
Where should the island go?
Usually under the brightest part of the roof and away from the main walkway to the garden. We test two or three layouts on the plan before deciding.
