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.

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.
