BIGGER IN BOSTON: There’s hardly a high-brow event in Boston where Chanel’s tweeds and interlocked Cs aren’t in evidence. So it’s fitting that after 15 years in a rather modest space overlooking the Public Garden, Chanel needs more room. In early 2013, the brand will move less than a block down Newbury Street to a new 10,000-square-foot boutique on the first two floors of number 6 Newbury. The new luxury residence building of six units is replacing a parking garage and is the first new construction in 75 years on the coveted “A” block of Newbury Street, between Arlington and Berkeley streets. Architects Richard Bertman and longtime Chanel collaborator Peter Marino designed a white French limestone facade with black etched moldings for the store. But the Chanel flair doesn’t end there. Above it, rectilinear window bays with black mullions give the residence floors a chic, quilted look. The store’s interior will evoke Coco Chanel’s Paris apartment, and will carry ready-to-wear, accessories, shoes, fragrance and beauty, fine jewelry and watches. A spokeswoman declined to provide further details.
