Do you need planning permission for a two-storey rear extension in Wimborne Minster?
The planning route for a two-storey rear extension in Wimborne Minster is set by England's householder rules and your council.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
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 Wimborne Minster like to extend?
Stone-built and rendered houses are common around Wimborne Minster, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

FAQ
Two-storey rear extension questions in Wimborne Minster
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 long does a rear extension take to build in Wimborne Minster?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.
What postcode areas do you cover around Wimborne Minster?
Including BH17 and BH18, and the surrounding Dorset area.
Do I need planning permission for a rear extension in Wimborne Minster?
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.
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.
