Piedmont Office Realty Trust and UBS have signed the biggest tenant at its 50-story Leo Burnett Building to another 50,000 square feet, filling the last of the remaining vacant space in the Loop tower.
With its new lease, the French advertising giant Publicis Groupe now occupies 682,000 square feet in the 1.1 million-square-foot building at 35 West Wacker Drive.
The building’s other tenant is the law firm Winston & Strawn, which has 430,000 square feet there.
CBRE’s Drew Nieman and Christy Domin represented the landlord in the transaction. Mike Christian and Steve Schneider of Cushman & Wakefield represented Publicis.
The tower was developed by John Buck & Company for the Leo Burnett advertising agency in 1989.
