The new roof amenity deck at 600 W. Chicago adds a large, dynamic outdoor space for the use of the building occupants featuring a sun deck, grilling areas, a fire pit and a private lounge and meeting area. The deck, set atop the building penthouse, offers great views of the city skyline to the east as well as views of the Chicago River to the west. Materials drawn from the industrial aesthetic of the building include IPE decking, concrete pavers, blackened steel, and zinc cladding. The design is organized around a linear pergola and a row of trees to unify the space and offer continuous sunshading. Densely planted areas scattered throughout the various spaces and continuous elements overhead also contribute to provide various shade and sun options for occupants.
