Marking a construction milestone for the new six-story Vast Bank headquarters under construction in downtown Tulsa next to ONEOK Field, developers, builders and tenants held a topping-off ceremony Feb. 28. The 100,000 square foot building is set to be completed in December 2019 and will feature a grab-and-go sushi bar from In the Raw, Hummingbird Coffee + Beer, rotating art exhibit and rentable rooftop terrace, the Rendezvous Room. Each floor will feature a terrace and view of ONEOK Field. Other tenants include BKD CPAs and Advisors and Casillas Petroleum. Additional space is still available for lease. The building was designed by KKT Architects and developed by the Ross Group.
