The concept idea for the development of the new residential and business area of Yancheng comes from the crystal sea-salt shape, as the city’s name means “City of Sault”. The towers have been immagined as crystal sault, while their bases, from which the towers are connected creating a retail area that promote cultural exchange and social development, remind to the tradition and shape of a Chinese fan. From the functional point of view, we have areas dedicated for relax/culture (the floating theathre), pedestrian pathways, a sport center, an artificial lake and many green areas, a “green lung” separating the new complex from the nearby highway. Moreover, the car circulation has been studied underground, for a better liveability of the whole. A balance between ECONOMIC opportunity, SOCIAL development and SUSTAINABLE living.
