(Atlanta INtown)- Atlanta-based undergarment-maker Spanx will open a flagship store and “world headquarters” at the new Buckhead Atlanta development.

The headquarters will occupy three floors, a rooftop garden terrace and additional balconies. The deal includes signage rights. Spanx is anticipated to move in November 2014.

In order to accommodate Spanx’s need for growth, Buckhead Atlanta is adding another level of office space that was not in the original development plan. The growing company will lease 86,000 square feet of office space, with an option to expand up to 112,000 square feet.

“We’re so excited to create a beautiful space for this leading Atlanta-based company,” said Morgan Dene Oliver, chief executive officer of San Diego-based developer OliverMcMillan. “Spanx’s innovative spirit and sense of fashion fit perfectly with the fabric of Buckhead Atlanta.”

“Like the Spanx brand, the Buckhead Atlanta space is innovative and unique,” said Spanx Founder Sara Blakely. “It’s a perfect fit…no pun intended! We’re also thrilled to offer hometown fans a way to experience the magic of Spanx at our first flagshape store.”

Hermès, the French high-fashion design house, will be one of the first of many upscale retailers to open at Buckhead Atlanta. The completed project, totaling 1.5 million square feet, will have 300,000 square feet of upscale retail stores, restaurants and cafes, 125,000 square feet of custom office space and 370 luxury high-rise residences.
