JPMorgan Chase Tower (formerly Texas Commerce Tower)

Hines built the tower as developer, with Texas Commerce Bancshares as its main tenant. The design came from I. M. Pei & Partners, the firm known today as Pei Cobb Freed & Partners, with I. M. Pei and Harold Fredenburgh as lead designers. Planning started in January 1978 and work on site in November of that year; Texas Commerce Tower was finished in August 1982.

Chase later took over Texas Commerce. Its name was on the tower until 2006, when the bank shifted most of its operations elsewhere; the building then went by its street address, 600 Travis, while the bank kept a foothold in the lobby until December 2018. JPMorgan Chase came back as anchor tenant under a 2020 lease, and its name returned to the building in 2021. That lease launched a makeover of the lobby and plaza, handed by the owners, Hines and Cerberus Capital Management, to HOK: the plaza is now an urban garden open to all, and a glass pyramid entrance, a nod to Pei's Louvre pyramid, links it to the lobby.

The tower has 75 floors and rises 1,002 feet, about 305 metres; it remains Houston's tallest building. Shearing one corner off at 45 degrees gives a slender, five-sided shaft, faced in polished granite with gray glass and stainless steel. The main facade spans 85 feet without a column, in butt-jointed glass and stainless steel; the loads that corner columns would usually carry are taken back to the structural core. The architectural historian Stephen Fox calls it "the quintessential skyscraper in the polished gray granite suit".

Pushed into one corner of the block, the tower leaves two-thirds of the site open for a public plaza. The plaza shows "Personage and Birds", a 1970 sculpture by Joan Miró.

A private office building, the tower can be seen from the streets of downtown Houston and from the public plaza in front of it, where the Miró sculpture stands.
