Permitted development rear extensions in Warwickshire
Designing to the no-application limits, with a lawful development certificate as proof. We design and build rear extensions across Warwickshire, from Nuneaton and Rugby to Royal Leamington Spa, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Warwickshire has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.

Do you need planning permission in Warwickshire?
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part 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.
