Urbanisation is reshaping the way we inhabit the planet. In Australia, 89% of us live in urban centres. In Singapore and other parts of Asia, this figure is even higher. We need to rethink the ways we live together in this rapidly changing space. Projects in this category seek to build cities that harness human knowledge and technology to shape cities that are smart, resilient and more liveable for all. The ten cities projects featured in this issue reflect the diversity and breadth of this topic. They explore everything from a developing arts precinct, to the modern urban ecosystem, to how high resolution 3D scanning can lead to a major step-change in the construction industry.
