Next in our high-tech architecture series is Renzo Piano's Kansai International Airport, which was built on an artificial island in Osaka Bay.
The high-tech architecture movement, of which the Italian architect Piano was a key proponent, was defined by buildings that utilised the latest developments in technology and industrial design.
Japan's Kansai International Airport, with its asymmetrical clear-span roof and visible structure, demonstrates many of the movement's qualities.
Writing for the New York Times when it opened in 1994, Paul Goldberger called Kansai International Airport "perhaps the most spectacular airport yet built, a mature work by one of the world's most intriguing architects and a dramatic work of engineering."
It was built on an artificial island three miles offshore so that it can run 24 hours a day, without disturbing the residents of Osaka.
Since it opened in 1994, the 1.1 mile long terminal has held the title of the longest airport in the world.

Renzo Piano Building Workshop won an international competition for the airport in 1988, with a design that resembles a glider plane in plan.
A total of 42 gates run along its wingspan, with the main body of the airport placed behind it like a fuselage. The building was arranged to be simple to navigate and had a light structure in order to deal with the risk of earthquakes.
