The Oklahoma Natural Gas Company Building was one of the first Art Deco buildings built in Tulsa. The selection of this style by a generally conservative utility company established its acceptance and paved the way for a host of Art Deco buildings which were to follow. This building is also significant historically because it reflects the tremendous growth of Tulsa from 1920 to 1930. By 1927, construction costs in downtown Tulsa were averaging one million dollars a month. By 1930, Tulsa had more buildings of ten or more stories than any city of its size in the world.
The Oklahoma Natural Gas Company Building is constructed of reinforced concrete, enclosed with buff tapestry brick and trimmed with Indiana limestone and vitreous tile. The height of its ten stories is enhanced by the piers which rise unbroken to the top of the building. The windows are inset between the piers and spandrels that are covered with decorative tile whose motifs include the stepped-in chevron and geometrical shapes of Art Deco design. The richness of materials and designs in the interior of the building are a significant feature of the Zig-Zag Art Deco style and contrast with the austerity of the later Streamline and Public Works Administration periods of Art Deco. The building continues to be a viable part of downtown Tulsa and provides a visible and tangible link to an important period in its past.The Oklahoma Natural Gas Building was listed in the National Register on April 10, 1984.
