Mid-Continent Tower

401 S Boston Ave. Tulsa, OK 74103

“TULSA’S MOST RECOGNIZABLE LANDMARK”

The Mid-Continent Tower’s elegant main lobby and entry colonnade is an homage to the timeless and classic Neo-Gothic designs established by Architect Henry Hoit in the Cosden Building’s 1918 lobby. The only way to faithfully match the Cosden’s original Calcutta Vagli Rosato marble was to use the original source. Modern architects traveled to Italy to personally select cuts that most closely matched the veining patterns that were popular during Cosden’s era. The interior wall panels required three different types of marble imported from Italy. Rosato covers the walls and columns; Roman Travertine graces the restroom walls while accents and trim are Verde Antique.

The lobby floors of both buildings are two colors from Tennessee—Craig Rose and Rose Gray. Hand-blown opal flash and opaque flash antique glass imported from Europe was used to compose the exquisite collection of stained glass art used extensively throughout the lobby and executive suites. Considered one of Tulsa’s most beautiful buildings, the Mid-Continent contains 321,500 square feet of uniquely dynamic office space. Within the stately design of the structure can be found available floor plans ranging from 300 to almost 12,000 square feet.

The Mid-Continent’s elegant finishes and have proven highly adaptable to modern design concepts. Tenants weary of cut-and-paste floor plans are often delighted by the myriad of opportunities for uncommon interior solutions. The building itself reflects a time long gone—a time of quality craftsmanship that built structural monuments intended to last for centuries. Having an address at the Mid-Continent Tower is more than prestige and convenience. It’s becoming part of the legacy that made Tulsa famous.

History & Architecture

Out of all the audacious personalities from Tulsa’s oil boom era, there was no ego quite so bold as refining and transportation magnate Josh Cosden’s. It was only fitting then that Tulsa’s most flamboyant oil man would build for himself a corporate castle grand enough to match his personality. A self-made man and professional risk-taker, Cosden funded his building with profits gleaned by out-maneuvering Pittsburgh steel magnate Charles M. Schwab in the $12 million Hill Oil deal, the “single greatest oil property in the world.”

True to his flamboyant nature, Cosden punctuated the transaction by casually writing a personal check for $7 million in the lobby of Hotel Tulsa in public view of his rivals. To put his signature on Tulsa’s skyline, Josh Cosden, a native of Baltimore, looked to the East Coast for influences. Business frequently took Cosden to New York City, where he became enamored with the Neo-Gothic architecture of lower Manhattan’s newest star attraction, the Woolworth Building.

Designed by Cass Gilbert, the “Cathedral of Commerce” was the world’s tallest building at the time and was frequently regaled as “one of the most beautiful in the world.” Cosden hired Kansas City architect Henry F. Hoit and his firm, Hoit, Price & Barnes, to build a sixteen-story, reinforced concrete reflection of Gilbert’s sixty-floor terra-cotta masterwork. Inside and out, Hoit’s design for the Cosden Building was replete with influences from the Woolworth Building. The base, cap, and window treatments flaunted similar Gothic touches, using motifs, ornaments, and segmented arches rendered in the same graceful terra-cotta cladding.

The Cosden Building was completed on the day World War I ended—Armistice Day, November 11, 1918. But almost as soon as the tower opened, a new war began brewing inside the Cosden Petroleum Companies. In a 1925 transaction described as “a forceful restructuring,” Cosden was removed by his board of directors. The action resulted in the Cosden Building becoming the official headquarters of Mid-Continent Petroleum and, eventually, home of the national DX Petroleum brand.

In 1977, Tulsa-based offshore petroleum giant, Reading & Bates, acquired the Mid-Continent Building for use as its international headquarters. By 1980, oil was booming as was Reading & Bates’ offshore oil platforms, engineers and architects devised a structural frame that rose 16 stories alongside the original Cosden building, cantilevered 40 feet over the Cosden, and then rose an additional 20 floors.

The feat resulted in a 527-foot matching addition to the Cosden Building that maintained a mere six inches of separation between the two structures. Midway through the project, the price of oil collapsed. Despite the resulting revenue crisis, Charles Thornton was unbending in his determination that they would finish what they started. He refused to compromise his vision of a new building of such quality that it would rival the original Cosden Building. Thornton’s dream was ultimately realized with the opening of the Mid-Continent Tower in 1984.
