This issue of Az W-Magazine Hintergrund is dedicated exclusively to the unique Architecture Lounge. As the Austrian architecture museum one of our major concerns is to strengthen the dialogue between architecture, politics and business. With this aim in mind a new platform was established 2004 in which market leaders – in terms of quantity and quality – are brought together. In this platform for committed businesses and associations top priority is given to the exchange of knowledge and the concept of networking. Hintergrund 52 traces the exciting development of the process of creation and provides unique insights into the past years.
