The master plan for the new headquarters of this oil and gas company weaves architecture and landscape architecture to balance company needs and civic engagement. The project renovates a Pietro Belluschi-designed tower as the centerpiece of the complex, re-uses and adds onto the empty 1923 Braniff Building, a National Register of Historic Place property, and creates a new iconic building for public and corporate use, 120 Kerr, whose transparency allows the events inside to activate the life of the city outside, true to the spirit of the overall design. A new ‘outdoor interior’ civic space connects the buildings on the site and enables employees and the community to enjoy native eco-regional landscapes in the city, protected from high street-level winds that currently discourage outdoor activity.
