919 Milam, Office skyscraper in downtown Houston, United States

919 Milam is a 24-story office tower completed in 1956 in downtown Houston, filling the block bounded by Milam, McKinney, Travis and Walker streets. Its shell was Houston's first all-aluminum curtain wall, designed by Kenneth Franzheim for the Bank of the Southwest. A 300-stall parking garage built into the lower floors cut leasable space to about 543,000 square feet.

Bank of the Southwest hired Kenneth Franzheim to design the 24-story building, constructed between 1953 and 1956. It was the first Houston building with an all-aluminum curtain-wall shell and one of the first three downtown buildings linked to the pedestrian tunnel system. The bank commissioned Florence Knoll to design the lobby, which held Rufino Tamayo's 13 x 45-foot painting America, bought in 1955 and sold to a private collector in 1993.

The bank hired Florence Knoll to design the lobby, which held Rufino Tamayo's 13-by-45-foot painting America, commissioned in 1955. The mural was sold to a private collector in 1993, so visitors today see the renovated lobby without it.

The building connects to Houston's underground pedestrian tunnel system, offering direct access to surrounding office complexes, hotels, and shops. This underground network is especially useful during hot or rainy weather.

The building's leasable area fell from 735,000 to 542,000 square feet after a 300-stall parking garage was built into its lower floors during the Hines partnership's ownership before 2007. The same owners spent $11 million renovating the lobby.
