Renaissance Tower (Dallas)
At the time of completion in 1974, it was the tallest building in Dallas at and was originally known as the First International Bancshares Tower (First International Bancshares, Inc. was the new holding company parent of First National Bank in Dallas). In 1985, it was surpassed by Fountain Place and Bank of America Plaza, which became Dallas's tallest building. It was also clear that Renaissance Tower would be overtaken by Comerica Bank Tower and Chase Tower then under construction. Therefore, in order to regain some status, the building underwent a major renovation in 1986 that included a re-glazed exterior and removal of the lighting on its sides. In 1986, James T.

In 1998, T.Stacy & Associates consolidated tracts of land at the building site, at the time a vacant lot, and sold it to Cousins Properties in 2001. Their original plan called for a building with 27 floors, but the final plan called for a tall building with 33 floors. As the building began construction on November 27, 2001, it became the tallest building in the United States of America to be constructed after the September 11 attacks. Construction was finished about 2 years later in 2003, and the tower was officially dedicated in 2004. It became the tallest building in Austin, Texas, and the fourth tallest building outside of Dallas and Houston, Texas (excluding the Tower of the Americas in San Antonio). In August 2003 cost of the building was estimated at $137 million.
