Working in Fareham
Postcode districts we cover around Fareham include PO13, PO14, PO15, PO16, PO17. The same team covers Gosport (4 miles), Portsmouth (5 miles), Waterlooville (7 miles), Havant (8 miles), all within easy reach.
For homes towards Isle of Wight, Cowes is around 8 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
Planning and approvals in Fareham
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.
Applications are decided by the local planning authority (your district, borough or unitary council).

How the project works
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
First, a site visit: we look at the house, garden, access and drains and listen to what you need.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
The price is fixed in writing once the design is settled, with a clear programme and payment stages.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Utility room extension questions answered
Will my neighbours in Fareham be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Fareham, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do I need building regulations approval in Fareham?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Does a utility extension need planning permission?
Often not, if it is single storey and within permitted development limits. We check this for your property.
How much does a utility room extension cost?
Our guide range is about £2,130 to £3,920 per m² including VAT, with a minimum of around £16,000. An 8 m² standard-spec utility is typically £20,000 to £25,500 in Fareham.
