One Cleveland Center

One Cleveland Center is the fifth tallest skyscraper located in downtown Cleveland, Ohio, following Erieview Tower. The building has 31 stories, rises to a height of 450 ft (137 m), and is located at 1375 East 9th Street. It has about 614,000 square feet (57,000 m2) of office space. The Tower was built at cost of $52,100,000. It was purchased on May 15, 2008 by Optima International LLC for $86.3 million.

Designed by KlingStubbins, One Cleveland Center has an angular, "silver chisel" design similar to that of New York City's Citigroup Center. The land the tower was built on was intended to be part of the I. M. Pei Erieview urban renewal plan. The site was cleared in 1963 but was not developed and was used as a parking lot. It was sold to Medical Mutual by John W. Galbreath in 1979 to develop a "people oriented" office building. Ground was broken on October 30, 1980 and construction was completed in 1983. The tower's base is structured into a five-story glass garden atrium. It also houses a fitness center on the top two floors of the contiguous parking structure, and a 450-seat conference center named the Forum Conference Center.

One Cleveland Center also uses Citigroup Center-style diagonal trusses. During construction of One Cleveland Center, the trusses were added to make the One Cleveland Center more rigid and able to handle Cleveland's sometimes windy downtown conditions, especially in the winter months. One Cleveland Center also uses Citigroup Center-style skin. The Trusses can be seen at night when the building is lit up.

When the tower was constructed, there was a ramp leading to the underground Erieview parking garage. The developer decided to make it a pathway connecting Erieview Tower to One Cleveland Center.

In 2003, CNBC reported from One Cleveland Center about an investment banker named Frank Gruttadauria. Gruttadauria worked for Lehman Brothers at their Cleveland Offices, which are based at One Cleveland Center. Gruttadauria was charged with embezzlement of investment funds from the Fazio family who at one time owned a Cleveland-area chain of grocery stores. He served some time in Federal jail.

In 2009, the plaza and landscaping of One Cleveland Center is going to renovated. On 8/25/2009, construction crews were demolishing the original 1983 designed plaza. In addition to the outdoor plaza, the 1983 lobby will also be renovated with new flooring, a new canopy entrance, new couches, and LCD display televisions and a news ticker in the lobby. Westlake Reed and Leskosky is main architect for the renovation of the lobby. It should be completed before the Cleveland Winter sets in.
