Do you need planning permission for a two-storey rear extension in Oxted?
Here is how the rules in England apply to a two-storey rear extension in Oxted.
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. 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 Oxted like to extend?
Commuter semis and detached houses make up much of Oxted, and longer gardens make England's prior approval route for deeper rear extensions worth considering.

FAQ
Two-storey rear extension questions in Oxted
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
How long does a rear extension take to build in Oxted?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can it be built on a terraced house?
Sometimes, but the upper floor is harder to get through planning on a terrace because of the effect on neighbours. A single-storey extension with a loft conversion is often an easier route.
Is the site visit in Oxted free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
