In-line stores at Lenox are currently all on the first floor, and the 35,000-sf addition will bring shops onto the second floor, in the development's Neiman Marcus wing. Work is set to begin on the center in the fall. Bloomingdale's and Macy's are Lenox's other anchor tenants.

The Neiman Marcus expansion follows the replacement last month of a Lord & Taylor with a Nordstrom at Phipps Plaza, Simon's upscale, 819,000-sf mall across the street from Lenox. Other Simon malls in the Atlanta area include Gwinnett Place in Duluth; the Mall of Georgia in Buford; Northlake Mall in Atlanta; and Town Center at Cobb in Kennesaw.

Simon owns 296 centers in North America, 51 in Europe and five in Japan. The Indianapolis-based REIT most recently opened the 1.5-million-sf St. Johns Town Center, an open-air development in Jacksonville, FL.
