We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a bungalow rear extension in Rustington?
Planning for a bungalow rear extension in Rustington follows the English householder rules.
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 Rustington like to extend?
Commuter semis and detached houses make up much of Rustington, and longer gardens make England's prior approval route for deeper rear extensions worth considering.
