The Chicago Gateway is composed of two vertical mixed-use towers supported by a leaning tower covered in a green roof. Offices and commercial space would reside in the vertical towers and residences in the leaning tower, which bridges over Lake Shore Drive. All of the structures are connected together via a vertical farm podium, and a network of sky bridges connects the towers and provides access to other nearby buildings.
Urban farming via hydroponics would take place inside the green podium, and a green roof would grow additional produce. Vegetables and herbs would be grown in mechanized hanging baskets in the hydroponic farm. Produce from the farm could be delivered via they sky bridges, and the public can access the building and use the elevated routes to travel around the city.
This design, which was created in 2007, was a finalist for the prestigious Schiff Foundation Fellowship.
