The 12th in the Serpentine Gallery’s annual architecture series, this year’s Serpentine Gallery Pavilion in Kensington Gardens has been designed by Herzog & de Meuron and Ai Weiwei, the design team behind for the Beijing National Stadium, star of the 2008 Olympic Games and commonly known as the “bird’s nest”. Twelve columns – each of which represents one of the 12 annual pavilions created so far (including this one) – support a floating platform roof standing 1.5 metres off the ground. The interior is clad in cork and the pavilion designed to “inspire visitors to look beneath the surface of the park as well as back in time across the ghosts of the earlier structures”. Open until 14th October. For more information, see www.serpentinegallery.org. PICTURE: Serpentine Gallery Pavilion 2012.
