Pennzoil Place was designed by renowned architects Philip Johnson and John Burgee and was named "Building of the Year" in 1975 by the New York Times architecture critic Ada Louise Huxtable. In the years following, ownership has heavily invested in the property's technology and digital infrastructure, resulting in the 2014 Digie Award for the "Most Intelligent Office Building." Today, the dramatic silhouette of Pennzoil Place remains an icon of design along the Houston skyline and a standard for innovation in the heart of the city's central business district.
