Do you need planning permission for a bungalow rear extension in North Walsham?
Whether your bungalow rear extension in North Walsham needs a planning application depends on its size, your house and any local restrictions.
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 North Walsham like to extend?

FAQ
Bungalow rear extension questions in North Walsham

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.

The same limits as a house: 3 or 4 metres in England, more with prior approval.
Can you match the brick or stone on my North Walsham house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
