The base along Michigan Avenue reinforces pedestrian-friendly activities while camouflaging the building’s parking structure. Warehouse-like punched openings along the building’s north end are juxtaposed with its modern counterpart of an over-sized glass façade and grand terraces to the south. An architectural blue fin frames and defines the building’s individual components, while a striking modern foil-like roof completes the building’s composition. Amenities include an exercise room, sun deck and a party room.
