300 South Riverside Plaza is a premier 23-story office tower encompassing approximately 1.1 million square feet in Chicago’s West Loop. Positioned along the west bank of the Chicago River, the building offers sweeping, unobstructed views and direct access to both Union Station and Ogilvie Transportation Center. Originally constructed in 1987 by the renowned architectural firm Skidmore, Owings & Merrill, the tower features a distinctive glass-and-steel design and a dual-core floorplate of 54,000 square feet—ideal for tenants seeking the presence of a full-floor layout with half-floor occupancy. Following a recent redevelopment by Third Millennium Group, the property now boasts a suite of high-end, tenant-exclusive amenities. These include a penthouse-level fitness center with spa-style features, a state-of-the-art conference facility, a private riverfront terrace, a seasonal outdoor plaza for events, a tenant lounge, a screening room, and secure bike storage. On-site dining is provided by Little Toasted, offering meals and beverages throughout the day, while additional conveniences include a newsstand and banking services from JP Morgan Chase. The building is LEED Gold Certified and incorporates sustainable features such as rooftop beehives and a high-efficiency air system that refreshes indoor air every 10 minutes.
