CHICAGO – Transwestern Real Estate Services announces it will relocate its Chicago office to 123 N. Wacker Drive, signing a long-term, 35,000-square-foot lease for the tower’s penthouse with a move-in slated for the fall of this year. The firm is departing its 200 W. Madison St. location after nearly 20 years. The Chicago office is one of two Transwestern locations in the metro area, with a second office in Rosemont serving the suburban office and industrial markets.
“Our new office signals the next phase of our successful growth in Chicago,” said Blake Johnson, who was appointed Executive Managing Director and Greater Chicago Market Leader at Transwestern in September 2025. “The distinctive penthouse space at 123 N. Wacker is ideally situated in the heart of the city and features a private rooftop. Our investment in this new workplace will benefit our current and future team members, furthering our culture of collaboration, innovation and high performance.”
Transwestern will occupy floors 28-30 of the building. The 28th floor features private outdoor space, while the 30th floor provides direct access to the building’s tenant lounge. The property also features a refreshed lobby, indoor/outdoor workspaces, a coffee bar, conferencing facilities and fitness center.
“The leasing velocity and daily occupancy numbers at 123 N. Wacker and other high-end office spaces show that downtown is back, and we’re excited to welcome Transwestern to this highly unique penthouse space,” said Austin Lusson, Director of Leasing at Sterling Bay.
Transwestern’s Agency Leasing team, led by Executive Vice President Eric Myers, will also partner with Sterling Bay in representing office leasing at 123 N. Wacker Drive this year. The Transwestern team has prior experience with leasing the building.
Transwestern was represented by Executive Managing Director Larry Serota. Russ Cora and Austin Lusson of Sterling Bay represented the landlord.
