“Despite living in a city that has more months of cold weather than warm, a growing number of Chicagoans are putting a serious premium on outdoor living space. Rooftop decks at luxurious high-rise rentals and condos are huge draws these days, and many building managers say it’s now de rigueur to offer loads of outdoor amenities—not to mention a great view—if they want to make it onto the list of the hottest buildings in Chicago.

And just off Michigan Avenue, the Optima Chicago Center’s (200 E. Illinois St., 312-527-0800) 41st-floor Sky Garden Terrace boasts an “Arizona modern” feel, explains leasing specialist Taylor Payne, with fire pits, serene desert grasses, and a massive Jacuzzi that can fit as many as 20 people. “The east side lounge area reminds me of Pop Art—bold and colorful. It’s really fun up there,” says Payne.”
