A fourth tenant signed a lease to move into 601W Companies’ redeveloped Old Main Post Office, meaning about 15 percent of the 2.8-million-square-foot complex is now accounted for.
Chicago-based ad agency AbelsonTaylor signed the 15-year lease for about 89,000 square feet in the massive building, according to the Chicago Tribune. The firm will move at least 100 employees from its existing offices at 33 West Monroe Street.
New York-based 601W in June announced it signed Walgreens to 200,000 square feet in the massive structure. In December, Ferrara Candy announced it would take 77,000 square feet in the building, and last month the Chicago Metropolitan Agency for Planning agreed to lease 49,000 square feet.
The $800 million building overhaul, which lead architecture firm Gensler calls the largest adaptive reuse project in the city’s history, is set to include a food hall and rooftop amenity deck. The first tenants are scheduled to move in later this year.
601W also is embarking on a $185 million effort to add an exterior elevator and rooftop observation deck to the Aon Center, and it’s also planning updates for the 40-story office tower it bought last year at 1 South Wacker Drive. [Chicago Tribune] — Alex Nitkin
