Description
Thoughtfully reimagined with a modern sensibility, Residence 9C at 170 East 77th Street is a turnkey four-bedroom, four-bathroom home defined by elevated design and exceptional craftsmanship. A gracious entry leads into the dramatic step-down living and dining room, an expansive entertaining space framed by oversized windows that flood the home with natural light. Custom built-ins and an 80-inch Dynasty linear electric fireplace anchor the room, while European 10-inch oak plank flooring and electric privacy shades add warmth.
The beautifully reimagined kitchen is both striking and highly functional, outfitted with floor-to-ceiling Scavolini cabinetry, a durable Dekton countertop with integrated sink, and a best-in-class suite of appliances including Thermador refrigeration, induction cooktop, wine storage, and Gaggenau oven, microwave, and built-in espresso machine. Privately positioned, the sprawling corner primary suite offers a serene retreat, complemented by custom room-darkening Hunter Douglas electric shades and dedicated Mitsubishi climate control. Spa-inspired baths are finished with honed natural stone slabs, Scavolini vanities, premium Gessi fixtures, concealed wall-hung toilets, upgraded shower systems, and radiant heated flooring in the primary bath, bringing a five-star hotel sensibility to everyday living.
Set within Diamond House, a full-service condominium in the heart of Lenox Hill, residents enjoy a 24-hour doorman, fitness center, roof deck, bike room, and a pet-friendly lifestyle. Perfectly positioned moments from Madison Avenue shopping, acclaimed dining, Central Park, and multiple transportation options, the residence offers exceptional convenience in one of the Upper East Side’s most sought-after neighborhoods.
