A new financial quarter is being built near the waterfront of Shanghai's old town. Designed by British architectural firms, Foster + Partners and Heatherwick Studio, the 420,000 square meter development includes two 180-meter-high landmark towers, containing offices, a boutique hotel, and a wide variety of luxury retail spaces. At the heart of the scheme is the arts and cultural center with a flexible façade that can be changed to dramatically alter the look of the building.
