The outer façade is a slightly tapering spiral of non-reflective glass rising into the clouds like Jack’s beanstalk, encasing within at some distance the inner façade, also of transparent glass, which looks like a tapering stack of cylinders. The 128 floors high tower, within the inner glass wall, houses offices and a 258 room hotel between its 84th and 110th floors, which is the second highest one in the world. Between its inner and outer facades lies the novelty of this tower, as this is where nine indoor public zones have been created, each replete with its own atrium, gardens, restaurants, cafes and retail spaces, affording 360’views of the outside. The Shanghai tower also scores high on sustainability as its special 120’ twisting façade creates lesser wind loads enabling it to be built with much less steel and concrete. Also, its double layered insulating glass façade is able to keep out temperature changes for longer reducing the need for air conditioning.
