The Architecture of Competitions presents and analyses outstanding projects that have resulted from competition procedures coordinated by [phase eins]. Filled with project illustrations from 2005 to 2008 for both private companies and public institutions in Germany, China and a few Arab and African countries, the volume exemplifies design methods and techniques of visualisation. Articles of a more general nature by the authors and guest contributions by Rodolfo Machado, Vladimír Slapeta, Jafar Tukan, and Peter Zlonicky discuss the architectural competition as a crucial instrument in the field of planning and, in particular, international perspectives for its use. Established in 1998, [phase eins]. is one of Germany's leading consultancy firms for project and competition management in architecture and urban design. The authors, Benjamin Hossbach and Christian Lehmhaus, are the owners and managing partners of the firm.
