Herzog and de Meuron / Ai Weiwei: Serpentine Gallery Pavilion 2012

Book excerpt: The design team responsible for the celebrated Beijing National Stadium, which was built for the 2008 Olympic Games, comes together again in London in 2012 for the Serpentine's acclaimed annual commission, being presented as part of the London 2012 Festival, the culmination of the Cultural Olympiad. The Pavilion is Herzog & de Meuron and Ai Weiwei's first collaborative built structure in the UK.This year's Pavilion will take visitors beneath the Serpentine's lawn to explore the hidden history of its previous Pavilions. Eleven columns characterising each past Pavilion and a twelfth column representing the current structure will support a floating platform roof 1.4 metres above ground.The Pavilion's interior is clad in cork, a sustainable building material chosen for its unique qualities and to echo the excavated earth.
