About This Property
TRIPLE-MINT SIX-BEDROOM DUPLEX - 79th St. Park/Madison
Ideally situated on the 14th and 15th floors of one of Manhattan's most distinguished prewar cooperatives, this massive and extraordinary six-bedroom duplex has been renovated to perfection and is in triple-mint, move-in condition.
With 39 windows spanning all four exposures, the residence is exceptionally bright throughout the day, while its grand proportions, soaring ceilings, exquisite prewar character, and sweeping open-city views create an extraordinary sense of scale and elegance.
A private elevator landing opens onto an impressive 18-foot gallery, which forms the gracious central axis of the main living level. To the south, the gallery leads to a spectacular 38-foot living room with soaring ceilings and oversized floor-to-ceiling windows framing expansive open-city views. Adjoining the living room is an inviting corner library, which also captures wonderful views to the south.
At the opposite end of the gallery is a gracious corner formal dining room, which can easily seat 24 or more guests. Adjacent to the dining room is arguably one of the most remarkable family room and kitchen spaces to be found in a prewar residence. Framed by open city and seemingly endless blue-sky views, this spectacular gathering space combines exceptional design with extraordinary functionality. The chef's kitchen features top-of-the-line appliances, abundant counter space, and exceptional storage, making this truly the heart of the home.
A full-size, windowed laundry room is conveniently located adjacent to the kitchen.
Two of the six generously proportioned bedrooms, each with a luxurious en-suite bath, complete the main level. A beautifully appointed powder room is discreetly positioned off the gallery.
The exceptionally private upper level is devoted to the remaining four bedrooms. Each of the upstairs bedrooms have generious proportions and offer beautifully renovated en-suite bathrooms and ample closet space. The magnificent primary suite features a large dressing room with an abundance of custom storage and breathtaking southern skyline views that stretch toward Midtown Manhattan
A secondary laundry room completes the upper-level of the home.
Throughout, the residence combines the gracious scale and architectural integrity of a classic prewar apartment with the quality, sophistication, and ease of a meticulous contemporary renovation. The result is a rare and remarkably complete home of exceptional elegance, comfort, and privacy.
Perfectly located between Park and Madison Avenues, 66 East 79th Street is one of the Upper East Side's most coveted full-service prewar cooperatives. Residents enjoy an exceptional level of service, privacy, and security, in a location surrounded by the finest shopping, dining, museums, and cultural institutions Manhattan has to offer.
The building permits 50% financing and there is a 2% flip tax.
Agent's Note
From Curtis Bain. Details about the apartment are drawn from the listing information provided through RLS by Brown Harris Stevens Residential Sales LLC.
Two floors of a prewar co-op on East 79th Street make up this six-bedroom duplex, and the scale shows right away. An 18-foot gallery runs through the main level to a 38-foot living room, with a corner library beside it that also faces south. I like that the gallery acts as the spine of the floor, so the living room, dining room and kitchen each feel separate without closing anything off.
The apartment has 39 windows on all four exposures, which means daylight reaches the rooms from several directions over the course of a day. The living room's floor-to-ceiling windows frame open city views, and the primary suite looks south toward Midtown. The main level's family room and kitchen are a strong part of the plan, with blue-sky views from the windows and a chef's kitchen that has top-of-the-line appliances, plenty of counter space and a lot of storage. The dining room is on the far end of the gallery and can seat 24 or more guests, so it works for a large table as well as everyday meals.
Laundry is in two places. A full-size, windowed laundry room sits next to the kitchen on the main level, and a second laundry room is on the upper level, so you won't have to carry things far. The apartment also has a washer and dryer in the unit.
Two of the six bedrooms are on the main level, and each has its own en-suite bath. The other four bedrooms are on the upper level, which is set apart from the rest of the home. The primary suite has a large dressing room with custom storage, and there are seven bathrooms and a powder room off the gallery.
The building has an elevator, and pets are allowed. 66 East 79th Street sits between Park and Madison Avenues, which puts the Madison Avenue shops and the Park Avenue side of the Upper East Side within a short walk.
