Description
Welcome to Residence 6A, an expansive 2,547-square-foot, loft-like four-bedroom, four-bathroom home with an in-unit washer/dryer, located in the heart of the Upper East Side within the full-service Diamond House condominium.
A gracious entry foyer with double coat closets opens to a sophisticated dining gallery and an impressive step-down great room overlooking 77th Street. The spacious living area features beamed ceilings, beautiful hardwood floors, casement windows, and abundant natural light.
The windowed eat-in chef’s kitchen is designed for both everyday living and entertaining, offering generous stone countertops, abundant custom cabinetry, a breakfast bar, and room for a dining table. Top-of-the-line stainless steel appliances include a Sub-Zero refrigerator and wine cooler, along with a Gaggenau cooktop and dual wall ovens.
Thoughtfully designed with two separate bedroom wings, the home offers exceptional privacy and flexibility. The corner primary suite features an East-facing bay window, a wall of custom closets, and a luxurious en-suite marble bathroom with a soaking tub, double vanity, and separate glass-enclosed shower.
The second bedroom, which also works beautifully as a home office, is conveniently located nearby and served by a full hall bathroom with a stall shower. The spacious third and fourth bedrooms each offer excellent closet space and their own full windowed bathrooms, with one enjoying en-suite access. The washer/dryer is discreetly located in the hallway of this bedroom wing.
The Diamond House is a distinguished prewar condominium with full-time staff and an impressive array of amenities, including a beautifully landscaped roof deck, fitness center, and bike room. Ideally situated on the Upper East Side, the residence is moments from the neighborhood’s finest cultural institutions, restaurants, shopping, and convenient public transportation.
A rare combination of scale, privacy, gracious entertaining space, and modern comfort in one of the Upper East Side’s most desirable locations.
Taxes reflected include condo abatement.
