Glenstar Unveils Renderings for Transformative $25M Redevelopment of 200 South Wacker Office Tower in Chicago’s West Loop

CHICAGO (Feb. 3, 2026) — Chicago-based Glenstar, together with a private investor, announced it has embarked on the $25 million transformative redevelopment of 200 South Wacker, a 40-story, Harry Weese-designed office tower that helped shape Chicago’s modern Wacker Drive corridor.

The redevelopment reactivates the architectural strengths of the steel-and-glass tower, including its generous setbacks that deliver exceptional natural light and sweeping views of the river and skyline, while also introducing a hospitality-driven amenity experience spanning five levels of the 761,775-square-foot building.

For the first time since the building’s completion, the entire lobby level and the amenity spaces will be comprehensively redeveloped. “The end result will be a highly visible, interconnected collection of amenities that tenants engage with daily, fostering energy and community,” said Michael Klein, co-founder and managing principal of Glenstar. “The connectivity between these unique spaces is quite special and will be a true differentiator in today’s office market.”

A New First Impression on Wacker Drive
Upon arrival, tenants and visitors will be greeted by new pavers and elevated landscaping, setting the tone for the experience within. According to Klein, these enhancements lead into a completely renovated three-story atrium lobby, where luxury finishes, warm materials, an illuminated architectural feature wall and layered lighting create dramatic sightlines and a sense of arrival.

Clear views extend across the lobby, beyond the redesigned elevator lobby, to the riverfront bar and lounge that invites tenants and their guests into the club-like experience. Spanning four floors, this tenant-exclusive destination is anchored by a new sculptural staircase connecting the lobby to the river level and second floor, reinforcing a sense of openness and fluidity.

“By seamlessly linking the building’s most active spaces, the lobby becomes a social hub that functions more like a hotel than a traditional office tower where tenants move naturally between work, meetings and moments of recharge—creating an environment that feels intuitive, energized and purpose-built for how people use offices today,” said Klein.

The ever-popular Mojo Coffee will feature a refreshed design and remain in its current first-floor location, where patrons can sip coffee while experiencing the buzz of Wacker Drive.

Vertically Connected Amenity Experience
The amenity experience at 200 South Wacker unfolds vertically, inviting tenants to move seamlessly between spaces designed for leisure, wellness and connection. At the river level, a golf club will feature two state-of-the-art simulators, a putting green for friendly competitions, club-style lounge seating and ample space for entertaining.

Returning to the lobby level, tenants can unwind in the riverfront lounge featuring a full-service bar and a grand fireplace that opens directly onto a newly expanded patio cantilevered over the riverfront with a large outdoor fire pit and lounge seating—creating one of the city’s most distinctive indoor-outdoor tenant environments.

Up the staircase on the second floor, tenants will find a parlor gaming area, enclosed library and a listening lounge, a creative space where people can gather, relax and enjoy their favorite music in an intimate setting.

Together, these spaces serve as the heart of the building, noted Klein, as they will support casual meetings, post-work gatherings and tenant events through Glenstar Connect, a proprietary tenant engagement program that fosters community and enhances day-to-day experiences through events, programming and building services.

Wellness Overlooking the River
The third floor will offer a new, full-floor health and wellness club overlooking the river, with dedicated areas for free weights, strength and recovery training, cardio, and a group fitness studio offering regularly programmed classes. Spa-inspired locker rooms will feature stylish vanity and dressing areas filled with natural light, along with cold plunges and infrared saunas.

Elevated Conference Experience
Showcasing panoramic views, including those of the Chicago River and Lake Michigan, the entire 34^th floor will be redefined as a premier conference center accommodating over 180 people. Designed to support a range of meeting and event formats, the space will include breakout rooms, pre- and post-function areas and a high-end executive suite for private meetings. Tenants will also have access to the adjacent rooftop deck.

Partners by Design serves as project architect and J.C. Anderson serves as general contractor. With architectural renderings complete, construction is expected to begin at the end of February, with full delivery by the end of 2026.

“Chicago’s office market is more competitive than ever, and tenants are gravitating to buildings that deliver a true, hospitality-driven experience,” said Klein. “At 200 South Wacker, we’re amplifying the property’s highly desirable West Loop and riverfront location, along with its unmatched transit access.”

Backed by Flexible, All-Cash Ownership
The redevelopment is supported by an all-cash ownership structure, giving Glenstar and its partner the flexibility to respond quickly to tenant needs and market dynamics.

Along with its trophy location directly across the river from Union Station, the transformation positions 200 South Wacker to capture renewed leasing momentum in the West Loop, where demand for high-quality, amenity-rich office space continues to outpace outdated inventory.

The repositioning of 200 South Wacker builds on Glenstar’s successful recapitalization of its Presidents Plaza office complex near O’Hare, where similar targeted investment and tenant-focused improvements spurred significant leasing momentum.

Flexible, Move-In-Ready Spec Suites
As part of 200 South Wacker’s redevelopment plan, Glenstar is wrapping up construction on five fully furnished, move-in-ready spec suites making up over 52,000 square feet to meet tenant demand for flexible space. Options range from a full-floor, 23,503-square-foot suite on the fifth floor to 5,000- to 10,000-square-foot suites on the 15th, 16th and 36th floors. Spec suite buildouts are underway and scheduled for completion by February 2026.

Glenstar serves as the property’s asset and property manager, while The Telos Group is the exclusive leasing agent. For leasing inquiries, contact Jack O’Brien or Colton Riemenschneider at The Telos Group.
