TU Delft and Lund University
After winning the 2019 design competition hosted by TU Delft study association, DBSG Stylos, and project organization Nieuw Delft, Green and Sundberg constructed their circular timber design in February of 2021. The watchtower, made almost entirely of timber, was constructed without glue, nails, or screws. This enables the temporary structure to follow basic principles of circularity by protecting the integrity of the timber.
