Toyo Ito has joined forces with Arup to design this year's summer pavilion on the lawns of the Serpentine Gallery in London's Kensington Gardens.
Painted white steel sheets were welded together to create the main structure - the design of which is based on an algorithm.
The shapes created in the roof and walls are filled alternately with glass and white aluminium panels. The pavilion opens on 12 July. For further details call 020 7298 1515.
