OIDN Watch’s Mail Hall features a handcrafted Venetian vault in a dramatic double-height space, illuminated to highlight its form. The open south facade brings in natural light and energy efficiency, while space and lighting express the brand’s identity without overt signage. The irregular floor plan is divided into triangular service and rectangular subject zones, including a half-circle entry, VIP room, and barn. Customized lighting and displays integrate watch collections, with rounded arches in the window display connecting interior and facade for a cohesive experience.
