900 North Michigan in Chicago is a 66-floor skyscraper completed in 1989. At 871 feet (265 m) tall, it is currently the seventh tallest building in Chicago and the 25th tallest in the United States (2008). It was developed by Urban Retail Properties in 1988 as an upscale sister to Water Tower Place. The building features a large, upscale shopping mall called 900 North Michigan Shops. Bloomingdales sits at the rear of its wide, six-story atrium, with other luxury shops and restaurants filling the rest.Condos occupy floors 21-28 since 2007, and the luxurious Four Seasons Hotel occupies the middle floors (32-46) of the tower. Floors 48-66 are part of the 132 East Delaware Residences; these 106 condominiums were part of the original building plan. A large 12-story parking garage, with retail on the ground level and a medical clinic atop, occupies the rear half of the block facing Rush Street, where the LiveRoof greenroof is situated.

Few people driving the ramps of the 900 North Michigan Avenue parking garage at Rush and Walton Streets in downtown Chicago know of its verdant green roof. Visible from surrounding office and residential towers, the 16,866 square foot green roof features five planting mixes in an irregular grid pattern. Plantings include Stonecrop, sedum, chives, and feather reed grass. The roof is adjacent to an accessible green roof designed for luxury condominium owners at The Residences at 900 North Michigan Avenue.Completed in July, 2008, the 900 N. Michigan Avenue parking garage greenroof design includes five mixes, two of which feature the new LiveRoof Deep System (6″) and include ornamental grasses. The LiveRoof Modular Green Roof Systems used are the Combination Deep System 6? & the Standard 4?.
