Shanghai Project - Vision 2020

With over 20 million people in its extended metropolitan area, Shanghai is China’s most populated city. With an area of nearly 5,300 km2 (2,046 sq mi), it is also one of the world’s largest urban areas - and it’s growing fast. On the third floor of the Shanghai Urban Planning Museum, there is what probably is the world’s largest scale model of a city. The room-sized model of central Shanghai in 2020, as envisioned by the urban planners, fills an area larger than 100 square meters.
