This living lab was built in Kloetinge (Zeeuws-Vlaanderen) at Emergis, a mental health institution, where the guest rooms were extended with a new circularly built wing. The units can be easily moved, and the rooms quickly rearranged. This allows Emergis to meet the ever-changing demand for housing. However, there will no longer be a need to build or disassemble, but simply make some easy adjustments, without wasting a lot of energy or material. The use of bio-based materials further reduces the ecological impact and ensures circularity at the end of life. Look at the video!
