Baubotanik is a building method in which architectural structures are created through the interaction of technical joints and plant growth. The term entails the practice of designing and building living structures using ''living plants''. In this regard, living and non-living elements are intertwined in such a way that they grow together into plant-technical composite structures. The Baubotanik method combines the aesthetic and ecological qualities of living trees with the static functions and structural requirements of buildings, thereby reducing the need for artificial building materials. The structures provide valuable habitats for a variety of animal species and make conventional foundations redundant, due to their root anchorage. The use of Baubotanik is not a new invention and can be found in various historical and cultural contexts, such as the ''Tanzlinden'' (“dancing lime”) tree in Germany and

living root bridge Living root bridges are a kind of tree shaping in which rivers are spanned by bridges formed out of the roots of ficus plants. Due to their being made from living, growing trees, they "show a very wide variety of structural typologies, with ...

) and are grown over rivers to form walkable bridges. While the process can take fifteen years to complete, the bridges can be reinforced with natural materials and can withstand the strongest tropical storms. Furthermore, since the turn of the millennium, ‘willow churches’ (made of willow rods and lacking a fixed roof) have been constructed on various former garden show grounds, yet provide only limited functionality as buildings.

An early publication in this field of study was the article ''Baubotanik: Mit lebenden Pflanzen konstruieren'' (translating to “Baubotanik: Designing with Living Plants) by Ferdinand Ludwig and Oliver Storz in 2005 in the magazine Baumeister. The term “Baubotanik” was defined in 2007 at the Institute of Theory of Architecture and Design (Institut für Grundlagen moderner Architektur und Entwerfen) at the

, where its concept was scientifically further developed. Within the scope of the research, simple experimental buildings were constructed, such as a footbridge and a Baubotanik tower that illustrated the possibilities of creating larger Baubotanik structures by adding individual plants. Moreover, a two-story bird-watching station was planted in the town of
