The Research Group Baubotanik developsbaubotanical techniques and design methods,which are used and
tested in different experimental buildings. Already in 2005, initial experiences could be gained at the student project "Footbridge". The "Baubotanical Tower", finished in 2009, uses the
technique of plant.Based on the same method,the Plane-Tree-Cube Nagold demonstrates the possibility of baubotanical design in an urban context for the first time.
