The Future of Skybridges at Greater Height

Antony Wood

, Chicago

If the horizontal growth of cities is considered unsustainable in terms of land use, infrastructure, energy use and pollution creation, then cities need to grow denser, and in many cases more vertical, to cope with the triple effects of global population growth, urbanization and changing social demographics. Yet all cities rely on the ground plane for circulation, recreation, public facilities, commercial facilities, quality urban habitat and the opportunity for community to develop. In the sustainable city of the future then, it would be beneficial for the ground plane to be notionally introduced at levels in the sky, through linking buildings with skybridges and skyplanes, which connect potentially "public" spaces within the towers. This presentation examined trends towards this around the world, as well as outlined some of the benefits and challenges in implementing such a vision.
