Description

Remarkable opportunity to own a 20 foot wide historic townhouse located on one of the most coveted blocks within the heart of the Upper East Side. Nestled between Park and Madison Avenues, the iconic 56 East 66th is located just steps away from Central Park, luxury boutiques, famous landmarks, museums and several world renowned five star restaurants. Neighbor to Andy Warhol's former residence, 56 East 66th Street fits seamlessly into this prime gold coast block with its brick facade and surroundings of spectacularly built homes and apartment buildings from the late 19th and early 20th century.

Currently configured as an 8 bedroom, 11 bathroom multi-family home with a doctor?s office on the ground floor this five story building will be delivered vacant.

Ideal for a one family residence conversion, the presently utilized 6,700 square feet may be built out to an entirety of 8,032 square feet for additional space to house extended family or work from home.

Walk into the entry foyer featuring one-of-a-kind mosaic tiles, a custom designed wrought iron door and original pre-war details.

The ground floor, complete with direct access to an expansive private backyard and connecting upper parlor floor, provides limitless options for transformation into the perfect kitchen or reception area. The parlor floor features dramatic double height ceilings, a fireplace, and large windows with north and south exposures. Currently set up as a private gallery space, this impressive enclave can be easily transformed into the main living/entertaining area of the residence.

Above the ground and parlor floors the building is currently configured into four one bedroom apartments and a two-bedroom duplex apartment. All apartments have fireplaces, loft like ceilings, oversized windows and are flooded with superior light.

Two combinable one bedroom one bath units are located on the second floor, with matching combinable one bedroom one bath units on the third and fourth floors north. The Duplex unit extends through the third and fourth floors on the south side and boasts an outdoor terrace with 190 square feet exterior space, ideal for sun worshippers and romantic late night dinners in the summertime.

The rooftop provides the perfect landscape to build a spacious outdoor oasis with capabilities for a greenhouse or gazebo, enclosed sun room and/or floral paradise. With divine views over rooftops of the city, this magical space may be extended to 75 feet from the existing 57 feet height if setback from the property line.

Building Information

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.
