The tech giant Apple has just spent five billion dollars building a campus in California's Silicon Valley. It's not alone in its architectural ambitions. The new Facebook HQ in London features trees, grass and plants. So what does a corporate headquarters tell us about a business? Is it an opportunity for a company to show off its wealth and attract the best talent or is it folly? Evan Davis and guests explore what the latest trends in corporate architecture reveal about our business leaders.

Guests:
Ken Shuttlewoth, founder of Make Architects
Helen Berresford, head of interior design at Sheppard Robson Architects
and Deyan Sudjic, director of the Design Museum.
