Dream Builders: Norman Foster

Razia Iqbal talks to architectural pioneer Sir Norman Foster (also known as Lord Foster of Thames Bank), whose 46-year-old practice spans project offices in more than 20 countries, has won 600 awards worldwide, and recently built the largest single building in the world, Beijing Airport. The audience will have the chance to direct questions as the architect talks about his international career and the projects, visions and odd controversies that have defined it.
