Several cases of these interventions are documented and classified by three thematic axes: design, building and living. This highlighted new trajectories for innovation in building technology, consistent with the social, economic and productive dynamics that no longer allows for growing performance by increasing the resource demand. A theoretic framework is traced supporting this vision, which shows how the low technologies can respond to the transition of the economic model from linear to circular. Within this trajectory, the low-tech design for remanufacturing represents a reference framework and a promising tool applicable to the building processes.

The enabling technologies and new paradigms for the transition to circular economy emerging from the European research scenario are also mapped, outlining z`the possible future developments in line with open technical and societal challenges.
