Architect Rafael Viñoly has revealed new images for NEMA, a skyscraper set to become the tallest residential rental tower in Chicago. Designed to evoke the structural system of the Willis Tower, the project is sited on the southwestern edge of Grant Park. The 76-story residential tower will create 800 rental units and is designed to be LEED Silver. The new skyscraper will include expansive views of the city’s skyline as it frames Lake Michigan and Grant Park.
