Architect Rafael Viñoly felt the pressure when tasked with designing the building that would become the Windy City’s tallest rental tower. “Chicago is the birthplace of American Architecture,” says Viñoly, who took inspiration from the iconic Willis Tower when creating NEMA Chicago, the 76-story tower under construction on the southwestern corner of Grant Park. The result is a glassy take on the older building’s bundled tube structure, which creates multiple rooftops while stabilizing the tower, allowing it to climb high into the sky and provide residents of these Downtown Chicago rentals with expansive views of Lake Michigan, nearby Grant Park, and the city’s skyline.
