Phillips 66 Headquarters
Houston, Texas, USA

“This is a great new chapter that we start writing for Phillips 66 today.”

Greg Garland
Chairman and CEO, Phillips 66

HOK designed this new headquarters to bring Phillips 66’s Houston-area employees together on a campus that supports collaboration and work-life balance.

Located on a 14-acre site in Houston’s vibrant Westchase District, the campus includes two office towers and a parking structure.

A landscaped arrival garden evokes feelings of a tranquil drive through Texas hill country. As visitors approach the lobby space, cascading water features enrich the arrival experience. The buildings’ first two levels are clad in a regional Texas limestone that continues from the exterior into the interior public spaces.

The building podium houses a conference and training center, a full servery and kitchen, an employee fitness center, and a central gathering and event space with an 80-foot x 210-foot glass skylight.

A bridge with kitchenettes, break areas and informal meeting spaces connects floors four through 13. The 14th and 15th floors feature an executive center, including a boardroom, executive suites and conference space.

All office levels have raised access floors that are flexible to support Phillips 66’s changing space and technology needs over time.

The fitness center includes basketball and volleyball courts, a massage room, a putting green, yoga and spinning studios, and a clinic with on-site medical and dental offices. A rooftop sports court above the parking structure includes a soccer field, track and exercise area.

The campus also contains vendor conference space, a public affairs studio, two credit union branches and an emergency operations center.
