How do you reveal a hidden space? Lighting serves as a powerful tool to activate and redefine urban environments. This night walk through the Dreispitz development area will explore how lighting can uncover and repurpose public spaces, focusing on its social aspect. The tour will examine the possibilities and impacts of dynamic lighting on various scales of use and perception within mixed-use developments. At Merian Garden, the discussion will shift to the environmental implications of lighting, with a focus on light pollution and the balance between urban illumination and dark sky preservation. Participants are invited to engage in a dialogue about their perceptions and expectations for how future lighting can shape and support new communities.
