As one of Chicago’s most modern (and luxurious) buildings, the 74-story 1000M brings a much-needed dose of sophistication to the Windy City. Though there are many social spaces throughout the Kara Mann-designed building, few are as enviable as the residents-only Club 1000, which is located on the 72nd-floor. Designed by The Design High, the sky-high sanctuary is peppered with verdant plants in the winter garden, 19-foot glass windows, and a fireplace. Just outside, the Sky Terrace overlooks Grant Park and Lake Michigan, complete with telescopes for celestial viewing. The cocktails from the full-service bar are just as memorable as the panoramic city views. And for the quintessential Chicago experience, residents can end the evening by eating a hot dog. Prices range from around $570,000 for a one-bedroom unit to around $8.1 million for a four-bedroom penthouse.
