The neoclassical architecture designed building is one of only two Rapp and Rapp buildings designed as an office building. Soon after the Old Dearborn Bank opened in 1928, it was acquired and its parent company was liquidated in the United States' Great Depression. The building, which is 27 stories high, was designated a Chicago Landmark on June 4, 2003. The 300ft light brown brick building with a steel structure includes 25 floors above ground and two below.The owners of the building defaulted on a $9 million loan from John Hancock Life Insurance resulting in the acquisition of the loan (and thus the property) for an undisclosed amount by Urban Street Properties LLC in April 2010. The building had been acquired by the previous owners for $9.5 million in 2001.
