Helmut Jahn's design for a 1001-foot South Loop apartment/condo tower arrived on the architectural scene with much excitement as Chicago appeared set to add multiple supertall buildings to its iconic skyline, joining Jeanne Gang's proposed Vista Tower in Lake Shore East.

Roosevelt , was heralded for bringing a transformative aesthetic balance to the horizon by bulking up the southern end of Grant Park with some much-needed height.
