The project calls for the structure to be historically renovated to house 98 boutique hotel rooms on floors 1 through 8, restaurant and retail on the first floor (6,800 square feet), and restaurant and bar space on the 11th floor (5,400 square feet), documents show.

The hotel rooms would be managed by Promise Hotels under Hilton’s Curio brand. Under the renovation, the ballroom on the ninth floor also would be restored.

Federal and state historic tax credits are being sought for the renovation, records indicate.

Reached via email, Ross Group President and CEO Warren Ross told the Tulsa World, “It is premature to make a statement regarding the potential development.”

Ross Group purchased the building, which has sat vacant for 22 years, for $1.5 million in September.

Among the oldest structures in downtown Tulsa, the 92,220-square-foot, 11-story building was constructed in 1927 as a joint venture between the Tulsa Club and the Tulsa Chamber of Commerce. Architect Bruce Goff designed the Zigzag art deco structure.

The Chamber of Commerce occupied the first five floors for 25 years, and the Tulsa Club filled the upper six with dining halls, dormitories, a gymnasium, a barber shop, and various lounges and libraries.
