Description

Overlooking the East River and offering South and East exposure, 9B showcases timeless elegance in a grand corner floor plan featuring four bedrooms, four bathrooms and a powder room. Designed by Robert A.M. Stern, one of the most celebrated architects of our time, 9B boasts brilliant light and expansive views from oversized casement windows, as well as custom moldings and baseboards throughout. The gracious 16 foot entrance gallery leads to a dramatic 47 foot entertaining expanse comprised of the dining room, living room and open chefs kitchen. Ceiling heights in the public rooms are approximately 11 feet, which add to the grand scale of the residence, as do the rift and quartersawn walnut stained Appalachian oak floors. The kitchen is equipped with custom shaker inspired millwork cabinetry, natural Brazilian quartzite countertops, Lefroy Brooks hardware, Gaggenau appliances and a center island with seating for four. The master bedroom faces South and is flanked by an en suite marble bathroom fitted with a custom designed double sink vanity and Wi Fi enabled heated flooring. Beyond the master bathroom is a luxurious walk in closet and dressing room. In addition, there are three gracious bedrooms each with its own en suite white marble bathroom. This spectacular residence offers a rare opportunity to live in one of the finest condominiums in Manhattan.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
