Bungalow rear extension in Fareham
Single-storey rear extensions that keep everything on one level. We design, get the approvals for and build rear extensions for bungalows in Fareham and the surrounding area, with one contract from the first survey to building control sign-off.
Fareham is covered from our Hampshire round, including PO14, PO15 and PO16. For Fareham bungalows we design the roof first, because the low eaves decide the height of the new room.

Do you need planning permission for a bungalow rear extension in Fareham?
Here is how the rules in England apply to a bungalow rear extension in Fareham.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Fareham like to extend?
Commuter semis and detached houses make up much of Fareham, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Bungalow rear extension questions in Fareham
Is the site visit in Fareham free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do I need planning permission for a rear extension in Fareham?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
Do I need to move out?
Rarely; the opening into the bungalow is made late in the build.
Can you match the brick or stone on my Fareham house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
