Do you need planning permission for a two-storey rear extension in Tilbury?
The planning route for a two-storey rear extension in Tilbury 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 Tilbury like to extend?
Tilbury mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

FAQ
Two-storey rear extension questions in Tilbury
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
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.
Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.
Is the site visit in Tilbury free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
What postcode areas do you cover around Tilbury?
Including RM16, RM17 and RM18, and the surrounding Essex area.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
