The systems that make up our cities are more intertwined than ever. It's no longer sufficient to design for transport, water, or energy in isolation. Infrastructure projects need to be seen through the twin-lenses of environmental and urban resilience. City design needs to be considered with respect to social systems like economics, health and education. To deliver truly sustainable solutions, it's important to take measure of these interdependencies. We believe understanding the relationship between people, place, and technology in the built environment is a good start.
