Today, Alan Titchmarsh is in Cambridge to help transform the garden of a mother whose son requires round the clock care. Suzi's son Isaac is confined to his bed or wheelchair and unsurprisingly she has been unable to spend any time on the garden which has become neglected. A huge space, Alan has an idea to bring some sun to the place and visits a garden in Chelmsford where the owner has recreated a Caribbean beach. Back in Cambridge, David Domoney sets to work to create a path which will give Isaac access to all parts of the garden. Frances Tophill fills the surrounding gravel beds with Mediterranean plants. Then, to round things off a state of the art sound system is installed along with an outdoor pizza oven and a sail shade.
