Bohlin Cywinski Jackson designed the Apple Retail Store on North Michigan Avenue in Chicago. Hoerr Schaudt Landscape Architects designed the green roof.
The simple box design has an entrance into a double space lobby, with a skylight overhead and central glass staircase. The apple logo faces the staircase on the opposite end. The exterior is clean white masonry, and the roof has green elements.
John Wellborn Root and Daniel Burnham designed the Rookery Building in Chicago Illinois, completed in 1888. Young Frank Lloyd Wright contributed to the project.
The innovative design gave rise to the skyscraper, a 12 story building with metal framing, elevators and large windows. The entrance's central light court displays the focus of the design: bringing light and elegance to the office spaces. Metal tracery and stone ornamentation fill the interiors and exterior. The structure combines exterior load-bearing walls and metal frame.
