This film is about the Swiss architects Jacques Herzog and Pierre de Meuron, who were jointly awarded the 2001 Pritzker Prize, their profession's highest honour, for combining "the artistry of an age-old profession with the fresh approach of a new century's technical capabilities". Over the past twenty years they have been involved in finding inventive architectural solutions to building a diverse range of projects - domestic, municipal and commercial - from a modest switching station for trains to a strikingly innovative approach to the design of a winery. Their highest profile commission to date was the conversion of London's giant Bankside power station into Tate Modern, acclaimed by their peers, the media and the public alike. Visiting examples of Herzog and de Meuron's ground-breaking style in Europe and Japan, this film reflects their capacity to astonish and explores the way in which they transform what might otherwise be ordinary shapes, materials and surfaces through new treatments and techniques. Their perspective on and approach to architecture; their design dialogue; the way their strengths and weaknesses complement each other; and their collaborations with others, particularly artists, will all be brought into focus to give a fascinating insight into the cutting edge of architecture today.
