At first glance, the Cosden Building, 409 S. Boston Ave., appears to be much taller than it really is. The structure — better known as the Mid-Continent Building — is 16 stories high and dates to 1918, but it appears to be more than 35 stories high, with a distinctive green roof that towers above most of the downtown skyline. The dramatic illusion is created by a 1980 addition that was constructed adjacent to the Cosden Building to support a 20-story tower cantilevered over the original structure.
This unusual design was necessary because the original buidling was not strong enough to support the weight of the additional floors. To preserve the aesthetic continuity, more than 85,000 pieces of terra cotta panels, spires, cornices and moldings were created for the exterior of the tower, according to the Mid-Continent Tower’s website. Construction on the tower finished in 1984.
According to the Tulsa Preservation Commission, the original 16-story building cost a million dollars to build — an extravagant amount in 1918. The Cosden Building was listed on the National Register of Historic Places in 1979.
The Cosden Building is one of more than 50 Tulsa buildings listed on the National Register of Historic Places — a list that also includes The Campbell Hotel.
