The first episode includes glimpses of some of their most stunning recent work, such as London's new 'Cheesegrater' skyscraper, Spaceport America and the KK100 skyscraper in China (the tallest tower ever built by a British architect), before looking in detail at some of their revolutionary projects from the 1960s and 70s.

This episode focuses on the 1980s, when modern architecture was deeply unpopular and under attack from the Prince of Wales. The architects reveal the dramatic stories behind some of their most famous creations, including Rogers's Lloyd's of London building and Foster's Stansted Airport.

The final episode focuses on the period from the late 90s to the present day, when they were at the peak of their success - building iconic landmarks across Britain and the world - but also faced some of the biggest controversies of their careers. Rogers reveals what went wrong with the Millennium Dome, Foster recalls the wobbles of London's Millennium Bridge and Michael Hopkins explains how his new parliamentary building, Portcullis House, became the most expensive office block in Britain.
