Standing at a structural height of 787 feet (240 m), it is the third tallest skyscraper in the city of Dallas. (If the antennas and spires of Renaissance Tower were excluded, Comerica Bank Tower would be the second tallest.) It is also the sixth tallest building in Texas and the 61st tallest building in the United States. The building was designed by Philip Johnson and John Burgee and was completed in 1987. The structure has 1,500,000 square feet (100,000 m2) of office space.
