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

FAQ
Two-storey rear extension questions in Kidlington
Can you match the brick or stone on my Kidlington house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
What is the 45-degree rule?
Many councils check that a two-storey extension does not cross a 45-degree line drawn from the nearest habitable window of the neighbouring house. We test it at the first drawing.
What postcode areas do you cover around Kidlington?
Including OX5, and the surrounding Oxfordshire area.
Is the site visit in Kidlington free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
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.
