Description
With 11ft+ ceilings and full 360-degree views of the Hudson River and the full Manhattan skyline comes the entire 17th floor of Norman Foster's masterpiece at 551 West 21st Street. Comprising over 8,100 square feet of light-filled space, this rare offering gives the new, lucky owner the ability to combine two massive apartments into one of the most significant homes downtown. The grand scale and proportions of the space along with the timeless interior design are the work of Lord Norman Foster. Floor-to-ceiling windows and four incredible exposures, west to the Hudson River, south to the Statue of Liberty, north up the Hudson past Hudson Yards and the Midtown skyline, and east across the Manhattan skyline, flood the residence with light and incredible sunsets, sunrises, and glittering night views of our city. Bring your architect, or simply keep it in the current format, where both homes are already in move-in condition, and you can live in one and rent the second home out, or simply keep it for family and guests. Discreet yet striking once you enter the ground, 551 West 21st Street, designed by Foster + Partners, is Norman Foster's first residential project in the United States to evoke serenity and calm in a bustling metropolis. Residents arrive through a private gated drive court into a 34-foot double-height lobby anchored by a sculptural chandelier. This luxurious building offers a full-time doorman, concierge, porter, and live-in resident manager, alongside a state-of-the-art fitness center with spa, sauna, and steam, a residents' lounge, children's playroom, and bicycle storage. Onsite car valet service for an additional cost is also available. Set in the heart of West Chelsea's Gallery District, with the High Line, Hudson Yards, Hudson River Park, Little Island, Chelsea Market, Faena, and the Heliport just moments away, this opportunity offers endless ways to live and enjoy all that is great about downtown living. Taxes listed with primary condo tax abatement.
