100% TREE

Authors: Gilbert Koskamp, Machiel Spaan, Pierre Jennen, Max Salzberger, Lorin Brasser

100% TREE invites readers into a vibrant journey of circular design, hands-on experimentation, and collective creativity. Born from the collaboration of teachers and students across Europe with TREE_TimberREengineered, this beautifully illustrated book captures how seven local trees were transformed into a single architectural story: a modest chicken-shed with an ambitious purpose. Through sketches, models, and reflections, it reveals how design thinking evolves when rooted in material awareness and teamwork, showing that true sustainability begins with learning, making, and rebuilding together. Part reflection, part inspiration, 100% TREE is both a record of process and a manifesto for a new way of crafting architecture.
