Do you need planning permission for a bungalow rear extension in Bridport?
The planning route for a bungalow rear extension in Bridport is set by England's householder rules and your council.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part 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 Bridport like to extend?
Stone-built and rendered houses are common around Bridport, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

Bungalow rear extension questions in Bridport
Is the site visit in Bridport free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
What postcode areas do you cover around Bridport?
Including DT6, and the surrounding Dorset area.

Can I live at home while the extension is built?

Do I need planning permission for a rear extension in Bridport?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
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.
