Terraced house rear extension in Banbury
For homes in Banbury, a terraced house rear extension is often the simplest way to gain space without moving. Rear and side return extensions for terraces, with access through the house and two neighbours. We take it from survey to completion certificate.
Banbury is covered from our Oxfordshire round, including OX16. On a Banbury terrace both neighbours usually need party wall notices or agreement, so we talk to them early.

Do you need planning permission for a terraced house rear extension in Banbury?
Planning for a terraced house rear extension in Banbury follows the English householder rules.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
Because rear extensions often sit on or near the boundary, the Party Wall etc. Act 1996 usually applies in England. Notices go out one or two months before work depending on the type of work, and a surveyor's award is only needed if a neighbour does not consent.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Banbury like to extend?
Commuter semis and detached houses make up much of Banbury, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Terraced house rear extension questions in Banbury
How long does a rear extension take to build in Banbury?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
How do you keep the house clean?
Dust screens, floor protection and a single protected route through the house.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
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.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
