JPMorgan Chase Tower, formerly Texas Commerce Tower, is a 305.41 m (1,002.0 ft), 75-story skyscraper in Houston, Texas. It is currently the tallest building in the city, the tallest building in Texas, the tallest five-sided building in the world, 12th tallest building in the United States, and the 54th tallest building in the world.
The tower was built in downtown Houston at 600 Travis Street in 1981 as Texas Commerce Tower. It was designed by noted architects I. M. Pei & Partners. In some early plans, the building reached up to 80 stories; however, the FAA expressed concern that additional height was a risk for aircraft going into and out of nearby William P. Hobby Airport. Nonetheless, when it was completed, it was the eighth tallest building in the world. The building was developed as part of a partnership between Texas Commerce Bank and Khalid bin Mahfouz.
Upon its completion, the building surpassed Aon Center in Los Angeles to become the tallest building in the United States west of the Mississippi River, a title it held until Los Angeles's Library Tower, now known as the U.S. Bank Tower, was built in 1990.
JPMorgan Chase Tower is also connected to the Houston Downtown Tunnel System. This system forms a network of subterranean, climate-controlled, pedestrian walkways that link twenty-five full city blocks. The lobby of JPMorgan Chase Tower has been designed to harmonize not only with the height of the structure but also with the portico of Jones Hall, home of the Houston Symphony Orchestra, and which occupies the city block immediately to the west. For that reason, a five-story glass wall supported by a stainless steel space frame spans the entire 85 foot width of the front entrance, making the lobby area light and airy, and opening up the space to the plaza outside.
