De Kopermolen was presented in 2015 in Vaals, Netherlands, as a group exhibition within a converted church building.

Dreber presented a series of works in dialogue with the architectural setting, alongside collaborative projects developed together with Alessandro De Matteis. The exhibition combined individual positions with shared installations, reflecting an intensive phase of collaboration.

The spatial context of the former church provided a structured yet open environment, allowing the works to unfold between autonomy and interaction.
