Description
The Collective Team presents Residence 5A at 40-42 West 17th Street, a true classic Flatiron loft with two bedrooms, two baths and a home office. Step inside and the scale takes over. Soaring 11'2" ceilings, exposed beams and a sweeping wall of oversized windows with original ornamental iron railings frame a dramatic living and dining room, made for entertaining, gallery walls and long dinners. Hardwood floors run throughout. The kitchen comes equipped with a gas range, a French-door refrigerator, a dishwasher and maple cabinetry. The two bedrooms sit on opposite sides of the living room for true privacy, and each has its own closet. A separate home office gives you room to work, create or unwind, and the second bath includes an in-unit washer/dryer. The building is a boutique 1910 cooperative with just 21 residences. Its Beaux-Arts facade sits in the heart of the Ladies' Mile Historic District, the storied stretch once lined with New York's grandest department stores. Residents enjoy an elevator and a common roof deck, along with rare flexibility. Subject to board approval, the building allows unlimited subletting, pets, pieds-à-terre, co-purchasing, and parents buying for their children. You're steps from Union Square's Greenmarket, Madison Square Park, Eataly and the best of Chelsea and the Flatiron District. Transit couldn't be easier, with the F, M, L, N, Q, R, W, 4, 5 and 6 trains all moments away, plus the PATH.
