## Property Overview

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. Residents enjoy more than 50,000 square feet of lifestyle amenities, highlighted by LA PALESTRA, a 40,000-square-foot athletic club and spa featuring a 75-foot swimming pool, 38-foot rock-climbing wall, basketball and squash courts, two-lane bowling alley, golf simulator, and lounge. The spa includes beautifully appointed locker and dressing rooms, sauna and steam rooms, and private treatment rooms. Additional amenities include an indoor playground designed by Kidville, a residents' lounge with catering kitchen, private screening room, game room, and landscaped garden courtyard.

 For the buyer with the vision to restore and reimagine it, this is a rare opportunity to create a stunning trophy Manhattan residence combining extraordinary scale, dramatic architectural volume, sweeping river views and substantial private outdoor space.

   The property is currently under contract, but is subject to an overbid process with other qualified purchasers being able to submit a higher and better offer, and Bankruptcy Court approval. The current deadline to submit a higher and better offer is 10:00 a.m. (EST) on October 29, 2026, the date of the scheduled sale hearing before the Bankruptcy Court. (This deadline is subject to change.) The minimum overbid price is $11,000,000, non-contingent, with a good faith deposit of not less than 5% of the bid amount required. Interested parties are invited to contact the exclusive listing agent for additional information.

Based on recorded sales at 50 Riverside Boulevard.

Years marked "thin" rest on fewer than 5 sales, where a single unusual apartment moves the median a long way. Read those points as the small samples they are rather than as the market turning.

Sales data through August 2026.

Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.

The City has not published the official FY2026/27 and FY2025/26 tax rates yet. We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one.

Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls.

Figures are the New York City Department of Finance assessment roll for tax lot 1011712549. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
