What will the city of the future look like? Don’t head to the cinema to glimpse the future city. Instead plan a visit to Istanbul, Songdo or Singapore. Each city’s depth and individuality will astound you, but also the ingenuity with which the challenges of overcrowding, depleted sources and stagnant economic growth have been met. Future cities seek inspiration from disruptive technology and innovation, an absolute need to rely on progressive energy sources, and from engaged citizens. Whether finding the answer in being a car-free city or regenerating water, the future city is smart, green, and efficient.
