Do you need planning permission for a two-storey rear extension in Sidmouth?
The planning route for a two-storey rear extension in Sidmouth 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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Sidmouth like to extend?
Stone-built and rendered houses are common around Sidmouth, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

FAQ
Two-storey rear extension questions in Sidmouth
Is the site visit in Sidmouth free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do you handle building control in Sidmouth?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.
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.
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 you match the brick or stone on my Sidmouth house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
