English: Built in 1918 as a Gothic Revival-style mid-rise, this building was designed by Henry F. Hoit for the Codsden Oil and Gas Company, and was expanded with a 20-story rooftop addition in 1980-1984, designed by Dewberry, which seamlessly blends with the original structure. The building stands 36 stories and 513 feet (156 meters) tall, and was the tallest building in Tulsa from 1918 until 1925, before losing this status to the Mayo Hotel. With the addition in 1984, the building became the 4th tallest building in Tulsa, retaining that status today. The building features a terra cotta-clad exterior with gothic tracery, one-over-one double-hung windows, a stone base, large arched bays at the base of the building with metal spandrels, an arcade at the entrance on the 4th Street facade, a clock mounted to the corner of the building, projected spandrels on the upper levels of the building, pinnacles atop the parapet of the original building, and a rooftop addition clad in terra cotta that matches the original building, with large bays at the top of the building, and a copper-clad mansard roof atop the building’s penthouse. Inside, the building features a lobby with vaulted ceilings, Gothic Revival-style light fixtures, marble-clad walls, decorative gothic reliefs, brass elevator doors, a sculpture of two oil workers, marble flooring, a sign board with a stained glass surround and brass clock face, and several stained glass ceilings. The building was listed on the National Register of Historic Places in 1979, and is a contributing structure in the Oil Capital Historic District, listed on the National Register of Historic Places in 2010. The building today houses various office tenants.
