Permitted development rear extensions in Tyne and Wear
Designing to the no-application limits, with a lawful development certificate as proof. Across Tyne and Wear we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Newcastle upon Tyne, Sunderland and South Shields.
Brick terraces, colliery houses and post-war semis make up much of Tyne and Wear. Former mining areas often need a coal mining risk check before foundations are designed.

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission in Tyne and Wear?
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.
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.

FAQ
Questions people ask
Is permitted development the same as planning permission?
No; it is a national grant of permission for work within set limits, so no application is needed.
Do I still need Building Regulations?
Yes, always.
Can my neighbours object?
Not to permitted development itself, though they can ask the council to check it complies. Prior approval does involve neighbour consultation.
