Tasked with negotiating an awkward floorplate in a historic tower, the design of 35 East Wacker deploys parametrically designed elements to provide wayfinding and security. Throughout twisting and jogging corridors over 800 unique colorful acrylic panels come together to provide a dynamic ceiling-scape that pulls workers through the space. In another corridor a 40’-long CNCmilled operable gate acts as a focal point in an otherwise blank hall, while strategically limiting access to the main bank of elevators. Made of readily available birch plywood, the gate also acts as a light scrim, dappling the hall with an undulating pattern. Together, the ceiling installation and the expansive gate, bring together function and aesthetics to otherwise unremarkable spaces.
