The specialized book "Walter Mair vs. 03 Arch" offers a deep insight into the creative engagement of the Munich architectural firm 03 Architekten with urban space. This volume impressively addresses the connection between architecture and photography. The Swiss photographer Walter Mair has captured the narrative qualities of urban designs in 20 large-format photographs. These photographs are complemented by short, associative texts from the architects, creating a dialogue between the visual and textual elements. The introductory essay by Hubertus Adam reflects on the fundamental issues of architectural photography and provides a theoretical framework for examining the works. This book is not only a documentation of architecture but also an artistic exploration of urban space and the life contexts that become visible in the buildings.
