Serpentine Gallery Pavilion 2013

Japanese architect Sou Fujimoto has been handed the task of trying to trump last year's incredible Herzog & de Meuron/Ai Weiwei pavilion. At 41, Fujimoto is the youngest architect to take on the Serpentine's annual temporary commission and his latticed, steel pole construction is heavily inspired by nature and nearly transparent. It's a flexible space with a cafe inside, and is a must-see during its four month tenure in Hyde Park.
