Filmed June 3, 2015, at the ULI Asia Pacific Summit in Tokyo, Japan. What are the challenges of maintaining attractive and livable cities? Since the 20th century, the concentration and density of the world’s major cities has dramatically increased. The most important issue of the "growing city" is preserving and increasing the well-being of its residents. As space becomes less available, architects look for innovative ways to create comfortable living conditions. In this session, Paul Tange, a leading proponent of vertical cities, discusses the state of cities, architecture, and space under the challenging conditions of the modern city. Discussion Leaders: * Paul Noritaka Tange of Tange Associates * Patrick L. Phillips of the Urban Land Institute
