This 10-room high floor corner duplex at 812 Park Avenue is absolute perfection. Each and every room faces either onto Park Avenue or picturesque 75th St, so the light is divine. Equally mesmerizing is the gorgeous sweeping staircase in the Gallery that distinguishes the apartments in this esteemed building. The entertaining rooms radiate off of the Gallery and include a supremely elegant Living Room with two exposures and a wood burning fireplace. There is also a handsome Library and a marvelous almost square-shaped Dining Room. In addition, the lower floor of the residence has a fantastic updated kitchen that overlooks the townhouses to the north and the iconic Carlyle. Plus, there is a Powder Room. Upstairs there are three lovely principal Bedrooms, all with en-suite baths and abundant closets. Of note, the Master wraps the corner and boasts double exposures which insures not only extra special light, but a rare sense of openness. Two of the three staff rooms with bath have been beautifully converted to create a perfect fourth Bedroom suite. Impeccably maintained under the thoughtful stewardship of the current owner, this apartment is fortunate to maintain many of the original details that are associated with the esteemed work of J.E.R Carpenter. Designed both for everyday living and for grand formal entertaining, the understated and timeless elegance of this almost house- like residence is certainly delightful.
