Symmetry of Pennzoil Place

Pennzoil Place is a set of two 36-story towers in downtown Houston, Texas, United States. ^[1] Designed by Philip Johnson and built in 1975, Pennzoil Place is Houston's most award-winning skyscraper and is widely known for its innovative design.^[2]

Pennzoil Place, developed and managed by Gerald D. Hines Interests, consists of two 495 f (150.8 m) trapezoidal towers placed ten feet apart and sheathed in dark bronze glass and aluminum. The buildings are mirror images of each other. ^[3] The entire street-level plaza joining the two structures is enclosed in a 115 foot glass pyramid-shaped atrium. ^[4] Deliberately designed as an optical illusion, Pennzoil Place's appearance will vary depending on the different locations from where it is viewed. Pennzoil Place is considered significant in architectural circles for breaking the modernist glass box design made popular by followers of Ludwig Mies van der Rohe and for introducing the era of postmodernism. ^[5] The buildings combined contain 1.4 million square feet of leasable space. ^[6]

Architect Philip Johnson was awarded the 1978 AIA Gold Medal and became the first laureate of the Pritzker Prize in Architecture in 1979 for his work on Pennzoil Place. ^[7] Pennzoil Place was named "Building of the Decade" in 1975 by New York Times architecture critic Ada Louise Huxtable because of the dramatic silhouette it added to the Houston skyline. ^[8]^[9]
