"WHAT is the city but the people?" asked William Shakespeare. But suburbs, and the separated houses that define them, were primarily designed to keep people apart. In the 1950s suburban dream, dad drove to work, mum ran the home and carbon was irrelevant.
At that time, traditional family households (mum, dad and one or more children) comprised half the homes of Sydney. Now, they make up only 32 per cent and in 20 years that will be just a quarter. Another quarter of the homes will have only one person in them.
