LONDON (REUTERS).- French architect Jean Nouvel has brought a vivid splash of red to London’s Serpentine Gallery with an asymmetric structure featuring red table tennis tables among activities on offer to visitors. The structure, Nouvel’s first completed building in Britain, is the 10th in the gallery’s annual series of architectural projects built outside the museum located in Kensington Gardens. The design for the 2010 Pavilion combines lightweight materials and metal structures, and everything is rendered in red reflecting internationally recognizable British images of traditional telephone boxes, post boxes and London buses. The building, unveiled on Tuesday, consists of bold geometric forms, large retractable awnings and a freestanding wall that climbs 12 meters (yards)
