Hudson Yards represents New York City's newest — and perhaps most ambitious — neighborhood, and this residence at the top of the market demonstrates exactly what the development has achieved. Floor-to-ceiling glass walls frame the Hudson River and entire city skyline; on clear days, the views extend to New Jersey and beyond. Gaggenau appliances, Italian marble, and custom millwork throughout. The building's amenities — spa, 75-foot pool, private residents' club — are the finest in the city.
