Duisburg-Nord Landscape Park in Germany, the Plateau de Kirchberg in Luxembourg, Parco Dora in Turin, Italy and numerous other projects designed and built by Peter Latz and Partners stand as examples of an up-to-date and intelligent approach to alternative environmental technologies and the reclamation of extensive industrial landscapes. In Peter Latz's landscape architecture, ecological and social concerns are translated into an individual aesthetic language that aims to achieve a timeless quality. The different layers and meanings of the sites rich in history are revealed and woven into networks of spatial and temporal relationships that follow rules of their own - the syntax of landscape. A sense of process and dynamism in sustainable landscape structures characterises the works, works that are open for change: they are spaces in development, not parks as finite set pieces. Peter Latz is professor emeritus of the Technische Universitat Munchen and has held guest professorships at the University of Pennsylvania and Harvard University. Udo Weilacher is professor for Landscape Architecture and Industrial Landscape at the Technische Universitat Munchen.
