Description

In Contract - Subject to Submission of Higher and Better Offers and Bankruptcy Court Approval. 21B at Extell's One Riverside Park is truly an extraordinary opportunity to acquire one of Manhattan's most distinctive residences: a dramatic 6000+ square-foot duplex offering exceptional scale, soaring double-height ceilings, walls of glass, expansive Hudson River views, and an enormous private terrace with a private outdoor swimming pool. The centerpiece of the residence is the spectacular double-height great room, where two stories of floor-to-ceiling windows create remarkable volume and light while framing sweeping views across the Hudson River. Grand proportions continue throughout the home, with expansive entertaining spaces, a large windowed kitchen, generously scaled bedroom suites, multiple exposures, and exceptional natural light. The sprawling private terrace is remarkable in both scale and possibility, providing an extraordinary setting for outdoor living and entertaining high above Manhattan and is complete with an exceptionally rare full sized private outdoor swimming pool. 7 Bedrooms, 9.5 Baths, tremendous storage, including his and her walk in closets, and bathes in the primary bedroom, formal dining and a massive kitchen with private den & dining spaces. Soaring ceilings range from 10 to 20 feet. One Riverside Park is an impeccably designed and managed full-service condominium offering exceptional white-glove service, including a 24-hour doorman and concierge.
