The widespread adoption of digital design technology means that we need not assume that city and building alike are most optimally rendered as a grid. Biomorphism, complex geometries, and sustainability can, and perhaps should be, intertwined in the tall buildings of the future, which may come to appear as geographic features more than extruded boxes in the years to come. In this session, three senior practitioners demonstrate through very different examples how tall buildings can provide an anchor for dense, diverse and sustainable urban development.
