The building’s name comes from two ideas embodied in its design: the idea of establishing dialogue with the water present in the city (The Park at Lake Shore East, Lake Michigan, Jay Pritzker Pavilion, BP Bridge, Cloud Gate), and the idea of giving the building a wet look on all four sides. These two key ideas come together to produce different exposure of the walls over the course of the year, creating a series of microclimates which are much easier to control, ensuring better performance of the building compared to a more regularly shaped prism.
The study of the impact of the wind also had some important surprises in store, because the jutting patios and wavy protuberances on the building create a windbreak effect which is very useful for reducing overall oscillation. The result is a disturbed, “confused” air flow which prevents the inconvenient “sail effect”, always a difficult structural challenge.
The figures are impressive: 1.9 million sq. ft., about 184,000 m2, with 6 levels of parking totalling 60,000 m2 (1,557 parking spots). The hotel measures 25,000 m2 (225 rooms) and the 264 apartments cover 84,000 m2. The tower contains office space, sports facilities, a drugstore and a café. And since the area on which the skyscraper stands measures 16,700 m2, its base occupies about six levels, distributed in different ways so as to provide service areas which may be accessed from outside without having to enter the core of the building.
