Description
6 West 20th Street represents the rare opportunity to acquire a full floor 4,100 square foot +/- loft of baronial proportions on one of the most desirable blocks in Flatiron. Upon entering via key locked elevator, one is instantly imparted with a sense of space so elusive in Manhattan. Located just off a gracious entrance gallery beckons the voluminous, light-filled great room. Soaring ceilings and classic industrial detail set the tone of this grand yet exceedingly warm space. The flow is ideal, with dedicated dining and living areas elegantly arranged around the large and fully equipped chef’s kitchen which features a full coterie of high-end appliances. Located just adjacent awaits the zen-like primary suite. Boasting a dedicated dressing room, custom fitted walk-in closet and an oversized spa bathroom, this sanctuary-like space offers a sense of tranquility in the heart of the city. The loft’s north wing encompasses a 50-foot expanse of the building’s West 20th Street façade. This flexible space, which can accommodate as many as 4 bedrooms, is currently configured as two bedrooms, a large playroom and a dedicated home office, all offering charming views over West 20th Street through eight oversized windows. A large media room, laundry room, prep kitchen and full bathroom complete this space, which also offers access to the building’s oversized freight elevator Ideally positioned at the epicenter of the Ladies' Mile Historic District in the heart of Flatiron, moments from Eataly, Whole Foods, and every form of transportation, restaurant, and amenity, 6 West 20th Street is a well-run coop with very low monthly carrying costs and superb provenance as home to countless creatives and some of the world's great photographers. Built in 1910, the building recently completed significant upgrades including a new lobby, new passenger and freight elevators, new water pipes, electrical risers and gas pipes throughout, as well as a new water pump system. A full time super is onsite from 8am until 4pm Monday through Friday. Pied-a-terres and co-purchasing are allowed and pets are welcome. This one-of-a-kind home is truly an extraordinary find. *Represents current apartment configuration, which may not conform to official legal documentation.
