One Atlantic Center (Atlanta, Georgia)

 office building, skyscraper, postmodern (architecture)

One Atlantic Center, also known as IBM Tower, is a skyscraper in Midtown Atlanta, Georgia, United States. It reaches a height of 820 ft (250 m) with 50 floors of office space and a floor area of 1,100,000 sq ft (102,000 m2). It is also served by 24 elevators. It was constructed from 1986 to 1987 and was the tallest building in Atlanta from 1987 until 1992. The building was commissioned by Prentiss Properties as a southeastern headquarters for IBM. Aside from introducing Atlanta to the postmodern architectural idiom of the 1980s, it is notable for essentially creating what is now the Midtown Commercial District. It had a very remote location and nevertheless opened fully occupied and thus attracted developers to Midtown in droves.

The exterior of One Atlantic Center consists of Spanish pink granite with a copper pyramidal top and gold peak. The design includes Gothic flourishes, most notably below the copper top of the building. At night, the peak and ridges along the top are illuminated brightly, creating a glowing effect.

One Atlantic Center was joined in 2001 by the Atlantic Center Plaza, which has similar postmodern design and was constructed as the second phase of the Atlantic Center development. The building was designed by Philip Johnson/Burgee Architects with Heery International, Inc., as associate architect, producing the contract documents. It was constructed by HC Beck.
