Rare Full Floor 1911 Condominium Never Before Seen 521 Park Avenue is one of a handful of buildings remaining from the first decade of the 20th century. Built in 1911, it is a rare condominium offering the grand proportions of buildings erected before the 1920's with 10.5 foot ceilings, all outside rooms, and over eighty feet of frontage facing Park Avenue. The sixth floor apartment, with 4,500 square feet and four exposures, was meticulously gut-renovated (completed in 2010) using absolutely the finest of materials and master craftsmanship to re-create the Neoclassical grandeur only matched by the building's magnificent Neo-Classical limestone facade. In the renovation, the apartment's floor plan was thoughtfully crafted to maximize the use of the square footage and create spacious rooms including a 40' living room along Park Avenue. While impeccably finished in every detail, all modern systems are discreetly concealed (including six zones for air conditioning and humidifying) to provide maximum comfort and achieve maximum beauty. The elevator opens onto a private windowed landing, which leads to the thirty-five foot long gallery lined with full limestone-paneled walls, Stalattile limestone inlaid panels and marble flooring, and a decorative fireplace with an antique marble mantel. This central gallery gives access to all public rooms and to the separate bedroom wing. Three sets of French-polished Mahogany and beveled-glass-paned double doors open into the living room, which features a wood burning fireplace with an antique mantel and five large windows overlooking Park Avenue. On the opposite side of the gallery, another pair of walnut and glass double doors frame the entrance to the spacious dining room which has three large windows and wainscot paneling. A special feature of the apartment is the spectacular walnut-paneled game room, off the living room and overlooking the Avenue, with a walnut-carved ceiling complete with a wood-burning antique fireplace. The living room, dining room, and game room each has custom parquet floors constructed from antique oak planking. The eat-in gourmet kitchen is fully paneled with limestone floors. It is outfitted with the highest-end appliances, including La Cornue Chateau stove and oven, custom oven hood, Sub-Zero refrigerator and freezer, Sub-Zero wine cooler with a 100 bottle capacity, Miele dishwasher, and an under-counter Dacor Microwave.
