There are solar panels on the roof and vegetables come from the allotment. For many years, there were chickens in the garden and meat from pigs reared with the help of friends. Clothes are hand-me-downs or pickings from charity shops, and evenings are often devoted to tackling issues raised by the community association. This isn’t life off the grid, in a wild, remote landscape. These are the choices made by a family of four in a terraced house on a council estate in Chichester, West Sussex.
