The first of its kind, the Fab Tree Hab is a terrestrial reef and grafted living tree structure. Shared by people and animals, this multispecies habitat combines indigenous tree-grafting techniques with computationally designed cross-laminated timber (CLT) scaffolds. The goal is to prototype a dwelling seamlessly integrated in its natural landscape and to replace harmful industrial materials with durable, bio-based alternatives. In every respect, this project generates life and minimizes carbon footprint, pushing the boundaries of regenerative design.
