Home furnishings giant Pottery Barn, Swedish children's apparel retailer Polarn O. Pyret, and local favorite Treat Cupcake Bar are the latest additions to the Chestnut Hill Shopping Center, according to WS Development, the owner and developer of the 406,000 s/f project. The new stores are scheduled to open in spring 2013 in a new building at the site of the former Macy's. Pottery Barn, a division of Williams-Sonoma Inc., features unique collections of home furnishings, designed in-house, that provide exceptional comfort, style and quality at excellent values, as well as home design services. Polarn O. Pyret is a children's apparel retailer that began its children's clothing business in Europe, introducing its now-standard striped apparel collection in 1976. Today, the company offers t-shirts, sweatshirts, pants, jackets, and more from its 140 stores in eight countries, including three in the U.S with two in New York City and one in Greenwich, Conn. At Treat Cupcake Bar, customers can enjoy freshly-made desserts, or build their own creations at its "deluxe make-it-yourself cupcake bar." Locally-owned Treat hosts birthday parties and caters special events, and has been featured on several media outlets including the Phantom Gourmet, TV Diner, and Improper Bostonian. "We're delighted to bring Pottery Barn, Polarn O. Pyret, and Treat Cupcake Bar to the Chestnut Hill Shopping Center," said Dick Marks, partner, WS Development. "We're pleased that our customers will have the opportunity to experience each retailer's commitment to customer service and quality." The new stores join others recently announced including The Sports Club/LA, Cinema de Lux, Shake Shack, Pinkberry, and gourmet Asian restaurant, Bernard's.
