During Into The Great Wide Open, we organize the Building Site of the Future: a temporary workspace at the festival site where sustainable construction and festival innovations are central. In collaboration with partners such as BAM, TBI, Top Sector Logistics, Team Infra, Triomf, Watermeln, Voskamp Groep, Greener Power Solutions, Foundation DOEN, and Lab Vlieland, we explore how building can be circular, biobased, and emission-free. This way, we show how we are working towards a circular and climatepositive future. The knowledge and experience we gain, we are happy to share with everyone involved in this major transition, both in the festival and construction sectors or in other ways.
