Do you need planning permission for a two-storey rear extension in Hurstpierpoint?
The planning route for a two-storey rear extension in Hurstpierpoint is set by England's householder rules and your council.
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 Hurstpierpoint like to extend?
Commuter semis and detached houses make up much of Hurstpierpoint, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

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