Pottery Barn, Polarn O. Pyret and Treat Cupcake Bar will soon be joining the lineup at the Chestnut Hill Shopping Center.

According to a press release issued by the shopping center's owner, WS Development, the three new retailers will open in spring 2013 as part of a new building currently being constructed on the former Macy's site. 

“We’re delighted to bring Pottery Barn, Polarn O. Pyret, and Treat Cupcake Bar to the Chestnut Hill Shopping Center,” Dick Marks, partner, WS Development, said in a press release. “We’re pleased that our customers will have the opportunity to experience each retailer’s commitment to customer service and quality.”

Treat Cupcake Bar, which currently has a location on Highland Avenue in Needham, offers customers a chance to choose from a selection of gourmet cupcakes or create their own. The local bakery is also known for helping out local non-profit organizations through its "Treat Others Well" program.

According to the press release, Polarn O. Pyret is a European, high-quality children’s apparel retailer with three other locations in the United States.

Pottery Barn, which is a division of Williams-Sonoma, currently has a location across Route 9 at the Atrium Mall. However, with the possible sale of the Atrium Mall in the future, Pottery Barn could have been looking for a new home in Chestnut Hill. 

Treat, Pottery Barn and Polarn O. Pyret will join Cinema de Lux, Pinkberry, Bernard's and Sports Club/LA in the new, 115,000-square-foot building that is part of WS Development's renovation and redesign of the Chestnut Hill Shopping Center.

Shake Shack also announced in May that it plans to open up in the former Rugged Bear location sometime next year.

In addition to tearing down Macy's and rebuilding on the site, WS Development also plans to demolish the City Sports/Century Bank building a few doors down at 33 Boylston St. That part of the project, which was presented to the city last summer, will result in a new, three-story, mixed-use building that will include retail stores as well as office space for WS Development.
