An exceptional offering for the discerning buyer seeking refined design, privacy, and architectural pedigree in one of Manhattan's most prestigious addresses.

Welcome to Residence 4B at 551 West 21st Street, a stunning west-facing condo in one of the finest, white-glove buildings in West Chelsea, designed by Foster + Partners-one of the world's most acclaimed architecture firms.

Spanning approximately 1,200 square feet, this loft-style two-bedroom, 1.5 bath home combines dramatic proportions, 10-foot ceilings, and floor-to-ceiling windows which frame spectacular Hudson River sunsets. The open living and dining area features stunning proportions, and flows into a Molteni & C Dada kitchen with beveled marble countertops, a Gaggenau cooktop, Sub-Zero refrigerator, and Miele appliances-ideal for both impressive entertaining and daily living.

The primary suite enjoys beautiful western light, abundant closets, and a spa-inspired bath with stone finishes and a cast-iron soaking tub. The second large bedroom could also be used as a home office or den, and includes two reach-in closets for ample storage. Additional highlights include a laundry room with a full-size washer/dryer, an elegant powder room, and exceptional sound insulation for total tranquility.

551 West 21st Street is an exclusive boutique condominium with only 40 residences and three per floor, offering privacy, prestige, and personalized service. The gorgeous, attended lobby with 34' ceilings provides automatic elevator access and a doorman who assists with valet parking, bicycle/stroller storage, and grocery delivery. Top-notch amenities include a fitness center with a pilates reformer room, spa and sauna, residents' lounge, game room, on-site parking, and live-in resident manager.

Situated on a quiet block lined with art galleries and fashion houses, the building is one of only two residential properties on the street, and in immediate proximity to Chelsea Piers, the High Line, the Hudson River Park's bicycle and running paths, and the neighborhood's vibrant restaurants and boutiques, including the new Faena Hotel, Chelsea Market, and the Meatpacking District. 21st Street is known for its community events and festive decorations, embodying the warmth of West Chelsea living.
