517 East 87th Street TriplexNew York, NY 10128

This extraordinary 25-foot-wide Upper East Side triplex residence lives like a private mini-townhouse—offering the size and scale of ~3,500 square feet within a boutique pre-war townhouse coop. Spanning the first two floors of the building plus a lower level space, this crown-jewel pairs timeless architectural presence with a rare 25-by-20-foot lushly landscaped private garden, creating an unparalleled indoor-outdoor lifestyle in the heart of Manhattan.
The parlor floor unfolds as the centerpiece of the residence, defined by soaring 11-foot ceilings, rich hardwood floors, and a wood-burning fireplace that anchors the living space with warmth and character. Expansive glass windows face directly the magnificent private garden – making it ideal for intimate evenings, elegant entertaining, or large-scale gatherings. The garden is beautifully maintained with a discreet automated irrigation system, ensuring year-round vibrancy.
Just beyond, the windowed kitchen blends warm granite countertops, classic wood cabinetry, stainless-steel appliances, and a vented hood, offering excellent storage and functionality. This level is thoughtfully arranged with a formal sitting room, dining area, media room, one bedroom, and a full bath—balancing gracious entertaining with comfortable daily living.
The upper-level features two generously proportioned bedrooms with en-suite baths, including a primary suite with walk-in closet, dressing area, and vanity station—providing serene and private quarters. A spa-like bath with steam shower enhances the retreat-like atmosphere.
A rare and valuable addition, the fully finished lower level offers exceptional flexibility for live-work, bonus space for staff, additional storage or otherwise.
It has a separate entrance, kitchen and bath; legally zoned for nonprofit or a doctor’s office, it conveys with the apartment.
Additional features include a 130-square-foot deeded storage room, in-unit washer and dryer, individually controlled air-conditioning units, and ceiling fans in every room. Polished onyx windowsills at street level add a subtle layer of architectural refinement throughout.
The pet-friendly cooperative offers low monthly charges and allows co-purchasing and pieds-à-terre with board approval on a case-by-case basis. Ideally situated just one block from Carl Schurz Park and Gracie Mansion, the home is moments from the Second Avenue subway, the 4/5/6 lines, neighborhood markets, and fine dining. For drivers, easy access to the FDR and convenient street parking complete the lifestyle appeal.
