Description
This luxurious ten-room duplex penthouse rests on one of the most prestigious white glove pre-war limestone co-ops Manhattan has to offer. With a gorgeous solarium and two huge private terraces, the penthouse at 829 Park Avenue is truly one of a kind. The home has undergone a complete state of the art renovation by SilverLining Interiors. All mechanical elements of this sophisticated home have been fully modernized including ten-zone central air conditioning, a Lutron lighting system, and an extensive audio/video system.
A private elevator landing opens directly into a gracious marble-floored entrance foyer with an elegant oval-curved staircase. Off the foyer is a beautifully proportioned grand corner living room graced with six south and west facing windows, a wood burning fireplace, and soaring ceilings reaching nearly 12 feet in height. Bordered by both a formal dining room and corner media/game room, this lavish wing of the home is meant for large-scale entertaining.
The windowed gourmet eat-in kitchen has custom-made cabinets, marble counter tops, and top-of-the-line appliances including a Subzero refrigerator, a range and grill, oven, warming drawer and microwave all by Viking, a Bosch Dishwasher, and a Shaw's original farm sink. There is a separate windowed breakfast area with built-in banquette as well as a butler's pantry and laundry area. A luxurious powder room and coat closet complete this space.
Down the gracious gallery, separate from the entertaining space, are the private quarters. The impressive southeast corner master bedroom suite has over 15 foot ceilings. There are two spacious windowed marble en-suite master bathrooms, one of which has a walk-in marble rain shower and the other has a bathtub. The suite also includes a huge windowed dressing/sitting room with custom cabinetry and built-ins. Also off of the gallery are two additional bedrooms, one facing east and the other facing south, with custom built-ins and ample storage space. They share a luxurious marble hallway bathroom and linen closet.
Up a sweeping curved staircase is the fourth bedroom with an en-suite bathroom located on the mezzanine level. Moving further up the staircase you will come to the dramatic solarium with a fireplace, floor-to-ceiling casement windows, and four exquisitely finished French doors which open onto two magnificent terraces, possessing absolutely breathtaking open city views.
Constructed in 1910, 829 Park Avenue has an interesting history. The building was featured in the prestigious American Institute of Architects' AIA Guide to New York City. Offering the luxury service one would expect from a building of this caliber, the building also features a beautifully renovated lobby, 24-hour doorman, on-site superintendent, and a fitness center. Located in one of the Upper East Side's most desirable neighborhoods, it is only two blocks from Central Park and one block from Madison Avenue's fabulous shopping, museums and restaurants. Pet friendly. There is a 1.5% flip tax payable by purchaser. A private storage unit is included.
