Thinking Outside the Box: Tapered, Tilted, Twisting Towers
Chicago, October 25 - 26, 2006

The CTBUH was delighted to return to Chicago, the home of the Council, with offices based at the Illinois Institute of Technology, College of Architecture. Chicago was the perfect venue for a conference on tall buildings, with its great skyline of spectacular towers and many more under construction. Many nations were represented by owners, architects, engineers, builders, building officials and technical specialists of all types related to the building industry. The conference theme "Thinking Outside the Box: Tapered, Tilted, Twisted Towers" was addressed by many of the world's leading experts in architecture, engineering and construction, with detailed investigations into many different aspects of these unusual articulated towers.
