Exxon, which is the world’s largest publicly traded company, is building a sprawling complex of low-rise office buildings, training centres, laboratories, and conference centres.
The huge campus, which will be on a 385-acre site on Exxon-owned land near I-45 and the Hardy Toll Road, will also include amenities such as a childcare centre and a wellness centre.
Most of the Exxon employees working in the company’s head office in Houston will be moved to the facility, as will those at the Exxon Mobil Chemical Company. In total, approximately 8,000 employees will move to the new site. The campus is due to be fully occupied by 2015.
Currently, Exxon occupies 2.2 million square feet of office space in Houston, most of it at the Hines Greenspoint Plaza Complex.
“This new campus provides an opportunity to consolidate many of our Houston offices in one location, which will provide a high-quality working environment as our employees continue to support ExxonMobil’s mission of delivering energy to meet growing global needs,” said Bryan Milton, President of ExxonMobil Global Services Company.
“The complex will be constructed to high standards of energy efficiency and environmental stewardship, and will promote new opportunities for employee collaboration in their daily work.”
Exxon stated that the decision to consolidate employees in one location followed a study of the company’s office requirements in the US. It added that it will wait before making a decision on whether employees from other locations in the country will be moved to the campus.
Editor’s notes: The campus opened in 2014 and, as of June 2023, Exxon Mobil still occupied the 385-acre campus. Further information about the Exxon Mobil Houston Campus – Energy Center can be found here.
