Cities are complex environments in which many functions need to be accommodated and a huge variety of opinions exist on how best to do that. Therefore, citizens and many stakeholder groups together shape the Built Environment; and vice versa: the Built Environment has the power to shape citizens and society. By being able to distinguish and understand the different systems at play in our urban environments – such as real estate markets, mobility, health and digital systems – future urban planning and design professionals can make sure value is created for city dwellers.
