CHICAGO – September 28, 2026 – Stream Realty Partners, a national commercial real estate firm offering an integrated platform of services, announces continued leasing momentum at The Wrigley Building, one of Chicago’s most recognizable landmarks, with more than 100,000 square feet of recent new and renewed leases alongside continued investment in the historic property.
Recent activity includes significant long-term commitments from global design firm Perkins&Will and materials manufacturer Oil-Dri Corporation of America. Perkins&Will has renewed its approximately 47,700-square-foot lease through 2038, while Oil-Dri has signed a new 15-year lease for approximately 19,500 square feet in newly designed space within the building.
The transactions build on broader leasing momentum at The Wrigley Building, including Chicago Fire Football Club signing a long-term, 30,000-square-foot lease and Health Wave Partners, a newly launched Chicago-based platform led by former Ventas executive John Cobb, choosing the property for its Chicago headquarters.
Stream Vice Presidents Erica Marshall and Katie Hull represent Mansueto Office Inc. in leasing at the property.
“The decision by these organizations to make long-term commitments to The Wrigley Building speaks volumes,” said Ari Glass of Mansueto Office. “Tenants are choosing an irreplaceable asset that combines iconic architecture, significant ownership investment, and an exceptional workplace experience in the heart of Chicago.”
Located at 400-410 N. Michigan Avenue at the intersection of the Chicago River, Michigan Avenue, and the Magnificent Mile, The Wrigley Building provides immediate access to some of Chicago’s most renowned dining, hospitality, entertainment, and cultural offerings. The property also features move-in-ready, furnished suites that pair modern workplace design with the historic landmark’s architectural character and prestigious address.
“The Magnificent Mile offers what many office districts aspire to create: an authentic, 24/7 neighborhood,” said Marshall. “From premier hotels and award-winning restaurants to the Riverwalk and some of Chicago’s most iconic destinations, employees can step out of the office and immediately connect with the best of the city. For companies focused on talent attraction, collaboration, and client engagement, that experience is a meaningful differentiator.”
Mansueto Office continues to make substantial investments in the property with a long-term focus on preserving and enhancing the landmark while meeting the expectations of today’s office users. Current investments include a multi-million-dollar elevator modernization program and planned enhancements to the tenant amenity experience. Existing amenities include a comprehensive amenity package, complimentary water taxi service, and curated tenant programming.
Holly Duran and Jeff Mulder of Colliers represented Perkins&Will in its transaction. Nicole Becker, Bess Cooney, and Sarah Silva of JLL represented Oil-Dri Corporation of America. Jon Milonas and Kyle Kamin of CBRE represented Health Wave Partners.
