From its beginnings in 1825 as a polytechnic school to the present day, the KIT Department of Architecture has continually grappled with the question of relevant research that is not only relevant to the discipline but also to society. And almost as a matter of course, this quest within the field of architecture is repeatedly reflected in actual built structures, in which new findings have been and continue to be tested and tried. For example, the main building of the Polytechnic, designed by Heinrich Hübsch and opened in 1836 at Kaiserstrasse 12 in Karlsruhe, can be understood both as a demonstration building showcasing newly researched materials and construction methods and as a teaching facility. Following this tradition, researchers in the Department of Architecture continue to explore the fundamental questions of the discipline, albeit against the backdrop of rapidly changing conditions—whether political, climate-related, or stemming from resource scarcity. The projects shown here therefore draw on the insights of a 200-year tradition of research in Karlsruhe, while simultaneously venturing into new and uncharted territory in search of answers to increasingly complex questions.
