Streeterville's Skyline Views Are Getting Even Better: 360 Chicago Expands, and Oak Street Scores a Stylish New Retail Building

By Socialhood News · Il/Chicago/Streeterville · May 11, 2026

Streeterville is doubling down on what makes it one of Chicago's most magnetic neighborhoods — stunning architecture, world-class views, and a street-level scene that keeps getting better. Two fresh developments this week are proof that the neighborhood's momentum shows no signs of slowing.

First, look up — way up. The beloved observatory at 875 N. Michigan Avenue, home to 360 Chicago, is set to expand into the building's two upper floors, promising an even more breathtaking perch above the lakefront. For a neighborhood icon that's long been a bucket-list stop for residents and visitors alike, this expansion signals a major reinvestment in one of Streeterville's most cherished vertical experiences.

Meanwhile, at street level, the Chicago Plan Commission has approved a landmark retail development at 67 E. Oak Street. The project will replace an existing five-story building with a sleek, 34-foot-tall, two-story glass-fronted retail structure — a design-forward addition that promises to energize one of Streeterville's most stylish corridors. Together, these projects paint a neighborhood that's committed to elevating every layer of the experience, from the sidewalk to the sky. Which of these updates has you most excited?
