The first five winners of this year's TED Prize for urban innovation have been announced. Recipients include London design studio 00:/ for its project WikiHouse, which involves the construction of wooden houses from a downloaded kit of parts.
This year, instead of going to individuals, the TED Prize was awarded to the concept of The City 2.0. Ten projects that improve urban life will each be given $10,000. Nominations for the next five winners are now being sought.
