From the original listing · Realtor.comShow

A grand Park Avenue residence, offered for the first time in generations, with leafy views and a prime location just moments from The Metropolitan Museum of Art and Central Park. Beautifully proportioned and rich in prewar character, this former classic seven is now configured as an expansive six-room home with nearly ten-foot ceilings, elegant crown moldings and beautifully preserved architectural detail. The entertaining rooms are particularly generous: a large living room centered on a fireplace, which can be converted back to wood-burning with board approval, and a formal dining room of substantial proportions, both overlooking the tree-lined avenue. The principal rooms are filled with soft natural light and a changing canopy of greenery. A Sonos sound system extends throughout the home. Three bedrooms and two windowed bathrooms provide excellent separation and privacy. The primary suite includes a windowed en-suite bath with heated floors and extensive closet space. The original maids room has been incorporated into the kitchen, creating an exceptionally large windowed eat-in kitchen, approximately 17'10" x 20'. It is equipped with a Wolf range and convection oven, an exterior-vented Wolf hood, Wolf warming drawer, farmhouse sink, Sub-Zero refrigeration with an additional double-drawer freezer, and a Miele dishwasher. A Miele washer and dryer are discreetly integrated into the kitchen. Two unusually large private basement storage rooms, approximately 9' x 13'6" and 11' x 6', are included in the sale. Designed by George and Edward Blum, 840 Park Avenue is a white-glove cooperative offering exceptional service and privacy. Museum Mile is moments away, with the boutiques, cafs and restaurants of Madison Avenue close by.
