What is a wraparound extension?
A wraparound extension combines a side return and a rear extension into one L-shaped addition. It gives the largest possible ground floor, often creating an open-plan kitchen, dining and living space across the whole width of the house.

Do you need planning permission for a wraparound extension in South Benfleet?
Approvals for a wraparound extension in South Benfleet follow the rules for England. In England a wraparound extension combines side and rear elements, which normally takes it outside permitted development, so a householder planning application is made.

Our first visit includes a check of your planning history, so you know the route before paying for drawings.
