The 41-story glass tower rising on the corner of Peachtree and 14th streets marks the tallest construction in Atlanta in more than a dozen years. But 1180 PEACHTREE, designed by the prestigious Connecticut firm Pickard Chilton, has more than height going for it. The buildings swooping lines evoke the contours of a gigantic, shimmering cell phone. Or is it a neo-gothic cathedral? Either way, its also the largest structure in Atlanta to attain green status; developer Hines Interests is constructing the tower using at least 10 percent recycled materials, and it will be outfitted with water-saver toilets and faucets. The high-rise, informally known as Symphony Tower, is scheduled to open next year, when mega-firm King & Spalding sets up shop on 17 floors.
