KKT transformed this 106-year-old former office building in downtown Tulsa, seamlessly blending modern amenities into its historic charm. The plumbing, electrical, mechanical and HVAC systems were replaced and elevators modernized, but key historic features such as the mail chute, plaster ceilings, and mosaic tile flooring are preserved. The mixed-use development now houses commercial space on the ground floor and 58 loft-style apartments. The roof boasts a large terrace with an outdoor kitchen. This project qualified for historic preservation tax credits gained through National Park Service approvals.
