The octagonal building has a ziggurat-like, stair-stepped top with lighting which accentuates the building at night. Completed in 1991, the building is 428 ft (130m) tall. It is one of several buildings built in a period in Atlanta in which architects apparently attempted to one-up each other with their ornate and dramatically-lit "wedding-cake" skyscraper tops. 1100 Peachtree received the EPA "Energy Star" designation in 2000, the first high-rise in Atlanta to be so-named. Building architects were Smallwood, Reynolds, Stewart, Stewart & Associates, Inc.
