In July 2016, Phillips 66 completed its move to a new permanent headquarters on a plot of land in Westchase. The new headquarters is between Westheimer Road and Briar Forest, in close proximity to the Sam Houston Tollway. Phillips 66 purchased the land from a subsidiary of Thomas Properties Group. The architect of record is HOK. The official groundbreaking was in November 2013, and the opening was completed on schedule. The 1.1 million square foot headquarters includes conference spaces, medical facilities, food service facilities, outdoor recreational space, a gymnasium with full-size basketball court, and training facilities. Irrigation of the outdoor landscaping is via a reclaimed water system. The new campus houses 2,200 workers who were spread among six different Houston locations, including the ConocoPhillips headquarters, where several hundred Phillips 66 workers had remained post spin-off.
