123 E 75th Street, 123 E 75th Street, 2/3 Ab Lenox Hill, New York

With approximately 3,500 square feet of interiors and an extraordinary 1,600 square feet of private outdoor space, Residence 2/3AB at 123 East 75th Street brings a remarkable sense of freedom to Upper East Side living. Set on a coveted block between Park and Lexington Avenues, this expansive duplex pairs the comfort and scale of a house with the convenience of a full-service building.

The terrace is the showstopper. Generously proportioned and framed by beautiful landscaping, it becomes an extension of the home, with room for morning coffee, long lunches, lively dinner parties, and quiet afternoons outside. There is necessary piping for a gas grill. Every room on the main level opens directly outdoors, allowing daily life to move effortlessly between the interiors and the greenery beyond. A sweeping, floor-to-ceiling curved glass window, a solarium, and a bay window draw that outdoor feeling deep into the residence.

Inside, there is room to come together and room to spread out. A collection of distinct living spaces includes a living room, dining room, solarium, den, office, and media room with a bar. Host dinner in one room while a movie plays in another. Find a quiet corner to work, read, or unwind. The layout offers exceptional flexibility, including the opportunity to transform the media room into a fourth bedroom suite with its own bathroom and walk-in closet. An additional oversized closet provides further space to reimagine.

At the center of it all, the open kitchen makes entertaining feel easy, with Viking and Sub-Zero appliances, a built-in coffee machine, and a breakfast bar for casual meals and conversation. A powder room completes the main level.

A curved staircase accented with Venetian plaster leads to a gracious upper landing and three generously sized bedrooms, each with its own bathroom and ample closet space. This thoughtful separation keeps the entertaining spaces below and the private retreats above. A dedicated laundry room with a high-capacity washer and vented dryer adds everyday convenience, while central air conditioning on the main level, individual bedroom HVAC units upstairs, and abundant storage complete the home.

123 East 75th Street is a full-service cooperative with a recently renovated entrance and lobby, a 24-hour doorman, resident manager, fitness center, private storage, and bicycle room. A garage is conveniently located next door. Pets and pied-à-terre ownership are permitted, along with gifting, guarantors, and parents purchasing for employed children. Up to 70% financing is allowed, and there is no flip tax.
