aqua towerThe Aqua Tower in Chicago is unusual for a couple of reasons. First, it has undulating balconies that make it appear to ripple. So it has a look that it is soft and flowing – which is not a common trait of steel and glass skyscrapers.
Another unusual trait is that it was designed by a female architect. Now it is not that there are so few female architects in the world, it is just not so often that a female architect gets to design and build a tall skyscraper.
If you look at most large-scale architectural projects in the world, very VERY few of them will be designed by women.
