Starting from zero, says Leonardo Ricci, 'is the point every man should arrive at. A man is a man when he finds himself alone and has to survive.' Ricci is an Italian architect, painter and urban planner. During the Second World War he saw communes rise spontaneously amidst the devastation in Sicily. Ever since he has worked to produce a radically new architecture, one which encourages a communal city life, and which also allows everyone to live within easy reach of the countryside. The programme was filmed in Sicily and Florence, his home city.
