Katten and Chubb Ink Big Renewals at Tishman Speyer’s 525 W. Monroe

Tishman Speyer said Thursday it had secured major lease extensions with Katten and Chubb, two of its longest-standing tenants at 525 W. Monroe St., the office building in downtown Chicago’s West Loop now undergoing a major redevelopment. Law firm Katten, among the property’s first tenants upon its 1983 completion, will maintain its 204,000-square-foot headquarters there. 

Based at the 25-story tower for more than two decades, Chubb—the world’s largest publicly traded property and casualty insurance company–will consolidate its local workforce from three Downtown Chicago offices into a newly designed 92,032-square-foot space. 

Tishman Speyer Managing Director Nooshin Felsenthal said Katten and Chubb’s renewed commitments “speak to the broader demand among leading companies to house their workforces in top-tier environments.”  

CBRE represented both tenants. Todd Lippman, James Whalen and Kyle Kamin represented Katten, while Lippman, Jon Milonas and Maura Flanagan represented Chubb. Ellen May and Olivia Parker represented Tishman Speyer in-house.
