Description

Residence 12B is a palatial five bedroom, five and a half bath home at 20 East End Avenue, a luxury condominium designed by the world-renowned architect Robert A.M. Stern. 12B benefits from features unique in the building with its soaring 13-foot ceilings, six Juliet balconies, and four exposures found throughout its 4,900 square feet.

Enter through either the formal front door landing or private direct elevator access leading to the home's gallery which includes a powder room and generous entry closet. The light-filled corner great room with double exposure to the south and east is highlighted through the oversized picture-perfect window and five floor-to-ceiling Juliet balconies that overlook the East River. The great room boasts a decorative marble fireplace and an integrated wine fridge and bar.

The home's comfortable elegance continues to the gracious eat-in kitchen and oversized den. The kitchen's classic aesthetic is blended seamlessly with a Gaggenau appliance package, vented stainless steel hood, and custom millwork with Calacatta Monarch countertops. Within the kitchen are a pair of extra-large pantries and a den. Along the gallery are two secondary bedrooms with en-suite bathrooms, one of which currently serves as the library.

Occupying the southwest corner is the beautiful primary suite that further invokes the home's timeless design. The bedroom features oversized windows, a Juliet balcony, and a separate sitting room flanked by double dressing rooms. Take reprieve in the marble-clad primary bath with radiant heat flooring, double vanities, a deep soaking tub, and a separate shower.

In the back of the apartment is the playroom, which can be easily converted back to a private en-suite bedroom, as well as the fifth bedroom and en-suite bath. A laundry room and mud room provide supplementary storage and complete the home. Additional in-residence features include herringbone oak floors, central air conditioning, automated lighting, and shades with built-in speakers throughout.

Completed in 2017, 20 East End Avenue is a 41-unit boutique condominium serviced by a 24-hour concierge and full-time resident manager. The building boasts a highly curated amenity package including a gated motor court, library, billiard room, game room, and children's playroom with a fitness center, and spa. Located on East End Avenue and 80th Street, the building is within close proximity to local eateries, shopping, and Carl Schurz Park.

The Upper East Side remains the gold standard for classic New York elegance. Known for 'Museum Mile' and its low-traffic, tree-lined streets, the neighborhood offers a refined lifestyle away from the midtown bustle. While famous for its historic cooperatives, the area has seen a recent surge in ultra-luxury new construction condos, particularly along the Second Avenue Subway corridor, making it a top choice for both traditionalists and modern buyers.
