Do you need planning permission for a two-storey rear extension in Chatteris?
Whether your two-storey rear extension in Chatteris needs a planning application depends on its size, your house and any local restrictions.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
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 Chatteris like to extend?
Chatteris mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.
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.
Do you handle building control in Chatteris?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
