Description
Welcome to 4 West 21st Street, a beautifully designed two-bedroom, two-bath loft condop in the heart of Flatiron, where sophisticated design, full-service amenities, and exceptional flexibility come together in one of Manhattan’s most coveted neighborhoods. Bathed in southern light through floor-to-ceiling windows, this elegant residence offers the scale and warmth loft buyers crave, with 9.5-foot ceilings, dark oak hardwood floors, and an expansive open layout that is both stylish and functional. The spacious living and dining area is ideal for everyday living, entertaining, or displaying a curated art collection. At the center of the home is a sleek open chef’s kitchen featuring Poliform Varenna white gloss cabinetry, solid Pied Auberge stone countertops and backsplash, a Sub-Zero refrigerator, Miele gas range and dishwasher, and an oversized island with an extra-large Kohler sink and garbage disposal. The primary suite is a true retreat, complete with a massive walk-in California Closet and a spa-like en-suite bathroom appointed with honed Glastos stone floors and walls, a Caesarstone double vanity, frameless glass shower, deep soaking tub, and radiant heated floors. The generously sized second bedroom easily accommodates a queen-size bed and also works beautifully as a home office, guest room, or nursery. Additional highlights include a full second bathroom, abundant closet space, and a vented washer/dryer. Designed in 2006 by renowned architect Hugh Hardy, 4 West 21st Street offers the rare combination of prewar loft character and modern condominium-style living. Residents enjoy a 24-hour doorman, fitness center, parking garage, 2,500-square-foot landscaped courtyard with children’s play area, and a highly regarded live-in superintendent. This highly desirable Flatiron condop offers remarkable ownership flexibility with no board approval required and permits pets, unlimited subletting, pieds-à-terre, co-purchasing, gifting, and parents buying for children. Ideally positioned near Madison Square Park, world-class dining, shopping, transportation, and the energy of Flatiron, NoMad, Chelsea, and Union Square, this is a rare opportunity to own a refined luxury loft in Flatiron Manhattan. There is an ongoing capital assessment of $894.31/month through June 2027. There is a tenant in place so 24hr minimum notice required. CONTACT US TODAY FOR A PRIVATE TOUR.
