418 E. 75th St.
Upper East Side
With exposed beam ceilings, huge skylights, and the soothing sound of running water from an indoor fountain, this expansive space feels more like a sanctuary than a home and garden design store. Co-owners Bunny Williams, an interior designer, and John Rosselli, an antiques dealer, met while attending the Chelsea Flower show in London, where they bonded over a mutual dissatisfaction with how difficult it was to find lovely things for the garden. In 1991, they opened Treillage in a former nineteenth-century blacksmith shop. Today, they fill the rooms with a mix of new and antique furniture (cast-iron tables, hand-carved limestone birdbaths, Chippendale garden chairs), lighting (copper-and-glass hand-blown lanterns, porcelain lamps, scrollwork sconces), urns, finials, topiary forms, and an assortment of vases and pots. While the staff is generally attentive, service can be a bit fickle on busy days. And they have much to keep them busy: They've been featured in Elle Decor, House & Garden, and Martha Stewart Living and have an impressive clientele (including Oscar de la Renta) rooted in New York, New Jersey, and Connecticut.
