The “treehugger”-pavilion was constructed for and exhibited at the National Garden Show (“BuGa”) in Koblenz, Germany, in summer 2011.It resulted from a research-project on digital design and construction methods that was initiated by Dipl.-Des. Christoph Krause, director of the Chamber of Skilled Craft’s “Center for Design, Manufacturing and Communication” in Koblenz in 2009 to educate students and craftsmen in a kind of digital mason’s lodge scenario. The design has been developed by students of the University of Applied Sciences in Trier, Germany, led by Prof. Holger Hoffmann and his Düsseldorf based office One Fine Day. Frankfurt based Office for Structural Design has been responsible for the structural engineering of the project. OCHS Holzbau, Kirchberg, executed the timber/steel-construction. In addition to the project’s mere architectural aspects an integrated interactive light-installation has been developed by the Faculty of Intermedia Design together with the Faculty of Computer Sciences, both from University of Applied Sciences, Trier, as well. “treehugger” was located next to basilica St. Castor in the vicinity of “Deutsches Eck” on a plot that has previously been used as a parking lot.
