Do you need planning permission for a kitchen-diner rear extension in Bridgwater?
Here is how the rules in England apply to a kitchen-diner rear extension in Bridgwater.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.
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 Bridgwater like to extend?
Stone-built and rendered houses are common around Bridgwater, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
