Twelve columnar supports, one for each of the Gallery's past pavilions, will support this floating roof and will, alternately, be covered with water to form a reflecting pool or drained to allow visitors to use the dry roof as a "dance floor or viewing platform," the designers suggest.
Herzog & de Meuron and Ai Weiwei join a long list of renowned Serpentine pavilion designers, including Pritzker Prize laureates Jean Nouvel (2010) and Kazuyo Sejima and Ryue Nishizawa of SANAA (2009); Frank Gehry (2008); Rem Koolhaas and Cecil Balmond with Arup (2006); and Zaha Hadid (2000), among others. The 2012 pavilion will be open from June 1 to October 14.
