Do you need planning permission for a bungalow rear extension in Bexhill-on-Sea?
The planning route for a bungalow rear extension in Bexhill-on-Sea 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 Bexhill-on-Sea like to extend?
Commuter semis and detached houses make up much of Bexhill-on-Sea, and longer gardens make England's prior approval route for deeper rear extensions worth considering.
