First transmitted in 1986, a look at how some young architects are reacting against modernist sterility with an exuberant return to traditional forms.

We are living in an age of experiment. The 80s have seen a rich crop of radical and controversial ideas about the form and content of buildings. This second of ten programmes looks at four high-profile movements in modern architecture.

Modern architecture has revived the concept of the open 'galleria' and the 'atrium'. All over the world the traditional town square is giving way to the pedestrian precinct and the shopping mall.

In Japan architects and designers enjoy a public fame and prestige far greater than any painter or sculptor. Three quarters of the 90 million people are packed into a narrow corridor, the strip of land between Tokyo and Hiroshima.

Stop the Bulldozer asks if conservation at all costs is inhibiting contemporary architecture. Conservationists have become a potent force in contemporary architecture, lamenting, and sometimes preventing, the demolition of old buildings and the destruction of our architectural heritage.
