Originally known as
Momentum Place, the tower was built as the new headquarters of MCorp Bank. The site, which included the
Woolf Brothers and
Volk Brothers department stores, was one of the busiest blocks in downtown Dallas. Adjacent blocks included the
Neiman Marcus Building,
Wilson Building,
Titche-Goettinger Building and
Mercantile National Bank Building. The entire block from Ervay to St. Paul was leveled to make way for the new tower. The original design as proposed by Johnson called for several office buildings, a hotel and a large shopping mall designed in an ornate classical style. MCorp Bank instead desired a more restrained office tower without any retail; the design for the banking hall was also scaled down. Construction began in 1985 and the tower opened in 1987, with MCorp initially leasing of space after moving from the
Mercantile National Bank Building. At time of completion it was the most legally-contested building on the Dallas skyline due to the economic downturn of the late 1980s and the
savings and loan scandal. MCorp Bank collapsed shortly after the building's opening and the bank was dissolved by
Bank One. Developers and financial backers sued over ownership of the tower. Other parties defaulted on loans, and the building went into foreclosure in 1991 and again in 1995, the two largest in city history. Without a lead tenant, the tower was remarketed into fully leasable class AA office space. Due to
the economic downturn, this was the last high-rise to be completed in
downtown in the 1980s. In 1997 Crescent Real Estate Equities, in partnership with the financer Trizec Properties, bought the Bank One Center from
Cigna and the
Teacher Retirement System of Texas for $238 million. On December 14, 2006, Crescent sold the structure for
US$216 million to
Los Angeles–based Metropolitan Real Estate Developers. On March 6, 2007,
Comerica announced its decision to relocate its corporate headquarters to Dallas. In August the company announced that it selected 1717 Main Street in
Downtown Dallas and that the tower would be renamed Comerica Bank Tower. The company executives began moving into 1717 Main Street in November 2007. The firm
TM Advertising planned to move into the building on January 2, 2008. It was scheduled to take four floors, with a total of of space. 340 employees were scheduled to move there. The space TM moved into was previously occupied by
TXU Energy. ==Design==
