Wrapped in floor-to-ceiling glass across triple exposures and with incredible Manhattan Skyline views and ceilings rising above 11 feet with 13 oversized bronze windows filling every room with light from morning through sunset. Designed to be like apartment houses of old but distinctly modern, the private elevator opens into a nearly 22-foot gallery primed for art and modern living. With oak herringbone floors throughout and a proper 30-foot living room with river views, this home makes an immediate impression of sheer space and volume. A media room/home office sits through oversized oak double doors. The windowed chef’s kitchen pairs rich oak millwork with marble countertops. A center island with counter seating anchors the room, a cushioned window seat offers a spot to linger, and a fully integrated suite of appliances from Gaggenau, Sub-Zero, and Miele keeps the lines clean. Just beyond, a formal dining room with skyline views seats 10. The primary suite occupies its own corner wing, with an over 22-foot bedroom, a dedicated dressing room, and a spa-like bath appointed with a freestanding soaking tub, double vanity, and glass-enclosed shower. Two additional bedrooms each have en-suite bathrooms, including a corner bedroom with sweeping views of Hudson Yards and Midtown. A laundry closet with washer and dryer completes the residence. Discreet yet striking once entering the grounds, 551W21 designed by Foster + Partners, is Lord Norman Foster's first residential project in the United States. It evokes serenity, elegance and calm in a bustling metropolis. Residents arrive through a private gated motor court with direct access 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 Hotel, and the Heliport just moments away, this opportunity offers endless ways to live and enjoy all that is great about downtown living.

Those are excluded from the benchmark below. ### How this price compares - **This home**: $11,650,000 - **Median sold price**: $8,000,000 - **Difference**: +$3,650,000 (+45.6%) - **This home, $/ft²**: $3,018 - **Median $/ft²**: $2,073 - **Comparable sales**: 5 - **Sales from**: January 2022 – July 2025 - **Middle half of those sales**: $4,950,000 – $9,700,000 Based on three-bedroom sales at 551 West 21. ### How these sales were negotiated - **Sale-to-list price**: 80% (3 sales) - **Sold below asking**: 100% (3 sales) - **Typical time to find a buyer**: 274 days (4 sales) - **Typical time to close**: 56 days (4 sales) Based on three-bedroom sales at 551 West 21 with the required listing and closing data. Sample sizes vary by metric. These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure. ### Price trend Median price per square foot, sales at 551 West 21 | Year | Median $/ft² | Sales | | --- | --- | --- | | 2016 | $3,249/ft² | 6 | | 2017 | $2,248/ft² | 9 | | 2021 | $2,073/ft² | 6 | | 2022 | $2,367/ft² | 5 | | 2024 | $2,513/ft² | 5 | | 2025 | $1,822/ft² | 3 (thin) | Based on recorded sales at 551 West 21. 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 September 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.
