Do you need planning permission for a two-storey rear extension in Golders Green?
Planning for a two-storey rear extension in Golders Green follows the English householder rules.
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 Golders Green like to extend?
Period terraces in Golders Green sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

FAQ
Two-storey rear extension questions in Golders Green
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.
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.
Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.
Do you handle building control in Golders Green?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
What postcode areas do you cover around Golders Green?
Including NW2, NW4 and NW11, and the surrounding Greater London area.
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.
