Autistic Alan Gardner heads to Bristol to help Ig, Jo and their three children transform their 100ft garden into an outside space that can be enjoyed by the whole family.
Currently a jungle of weeds and rubbish and with just £15,000 to carry out the work, Alan has quite a challenge.
Also tonight Alan visits the beautiful gardens at art museum The Getty Centre, in Los Angeles, where he discovers that geometrical order is the key to the design.
