When designers Kari Sigerson and Miranda Morrison wandered past an open space for lease on the Upper East Side a few months ago, they knew they had to have it. But just what they would do with the space, on East 71st Street, was still a mystery. Well, consider the mystery solved.

The new Sigerson Morrison store is being dubbed a “laboratory boutique,” allowing the designers to sell and showcase some of their favorite products, in a relaxed and intimate manner. The store will sell Sigerson Morrison’s line of covet-worthy shoes and accessories, along with esoteric items that indulge and share the designers’ enthusiasms, like stationery, jewelry, books, fragrances and candles. The space will also host small shows and intimate exhibitions to promote collaborations with fellow designers and artists.

Sigerson and Morrison have selected wallpaper designer and artist Dan Funderburgh as the first to present his work at the boutique. The exhibition will feature a large-scale wall covering installation, as well as limited-edition prints and accessories for sale.

As for future plans, the designers won’t reveal what they have in store, though they say it will maintain the personal nature of the 71st street shop, adding, “The laboratory boutique is a place to explore what resonates with us.”

Funderburgh will be on hand for the opening reception tomorrow, from 6:30-9:00 p.m. The exhibition runs until April. The Sigerson Morrison laboratory boutique is located on 19 East 71st Street, in New York.
