BOK Park Plaza at 499 Sheridan

Oklahoma City, Oklahoma

700,000 GSF

A beautiful addition to Downtown Oklahoma City’s skyline, 499 Sheridan is the second building to be constructed on the Devon Corporate Headquarters Campus. Devon Energy is the anchor tenant of this multi-tenant high-rise. The tower is connected to the existing 1.9 million-gross-square-foot Devon Energy Center via a 144-foot skybridge and a 60-foot skybridge connects the 499 tower with the new parking structure.

The architecturally modern Devon Corporate Campus Expansion integrates rich, historical architecture elements on the facade, featuring building components from Oklahoma City’s 1930 thriving main street. The glass skin of the building was designed to complement, but not duplicate, the facade of Devon Energy Center. The lobby has a mix of wood wall coverings that create a similar impression. The passenger elevator shaft is pressurized to eliminate lobby doors on office floors.
The 32-story facility provides 700,000-gross-square-feet of corporate office space, as well as two parking structures for Devon Energy employees.
