Do you need planning permission for a two-storey rear extension in Sheffield?
Here is how the rules in England apply to a two-storey rear extension in Sheffield.
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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Sheffield like to extend?
Sheffield has through terraces and some back-to-backs as well as later semis; back-to-backs have little or no rear space, so we look at side or loft options there.

Can you match the brick or stone on my Sheffield house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
