This gorgeous four bedroom, four bathroom triplex condominium is a perfect blend of security with the convenience of a full-service doorman building and a boutique feel of a modern townhouse. Residence 5 spans 3,375 square feet across the 10th, 11th and 12th floors and is defined by its expansive scale, sun-filled interiors, and a carefully considered sense of privacy. Designed and built by FLANK Architecture, the building introduces a contemporary presence to the neighborhood through its anodized metal and fritted glass facade, offering a striking contrast to the surrounding collection of stately pre-war residences. Each level of the home is accessed directly by elevator, creating a seamless arrival experience with separation between living spaces and bedroom suites. The layout unfolds across multiple entertaining and living areas, allowing the home to feel both expansive yet intimate. The vented chef's kitchen is designed with equal attention to performance and craftsmanship, featuring imported maple cabinetry with custom hardware, Calacatta marble countertops, a Sub-Zero refrigerator, and a La Cornue range that anchors the space as both functional centerpiece and design statement. Throughout the residence, hardwood floors, endless closets, and four marble bathrooms reinforce a cohesive palette. The oversized primary bedroom features stunning south-eastern exposures. The primary bathroom is enhanced by radiant heated floors, while a fully integrated home automation and security system supports modern comfort and discretion. Custom-designed windows were thoughtfully designed to maximize privacy while flooding the home with sunlight, which pours in from its North, South and East exposures. Positioned along a quiet, tree-lined stretch of East 57th Street, the residence is surrounded by Gilded Age townhomes and classic cooperatives, offering a calm residential setting moments from Midtown and the boutiques, galleries, and dining of the Upper East Side. The result is a home that balances architectural distinction with everyday livability in one of Manhattan's most established enclaves. Please note taxes shown include the primary residence condo tax abatement.
