ACTANT FOREST is a decentralized design research collective forming teams for each project. Through an interdisciplinary and holistic approach, we seek to deeply understand both natural and urban environments, and by transcending the boundaries between the two, to make valuable proposals for contemporary life in the midst of rapid change.
