The era, in which architecture was the most important field of experimentation in terms of new artistic and scientific ideas, has long passed. Today, architecture generally reacts to innovations in the field of economy, technology and society. The architectural journal Arch+ is one of the few magazines that has maintained its ambition to shape theory and to lead the debate. As chief editor for twenty years, Nikolaus Kuhnert has made Arch+ into the most important German medium for architectural and urbanistic discussions. In essays and interviews, above all as initiator and moderator Kuhnert has assembled the most important international authors in the recent past and thereby has publicized in Germany themes such as deconstruction, the dissolution of cities, new media, new geometries, new building materials or technologies. As a spearhead for a second modernism, Kuhnert has once again made architecture into a laboratory of ideas that extends far beyond the act of building.
