## Property Overview

Enjoy living in this expansive, ultra-luxe, south-facing one-bedroom home, designed by Lord Norman Foster of Foster + Partners, defined by its expertly crafted finishes and beautifully proportioned spaces, unlike many brand new buildings where proportions keep shrinking. With almost 40 feet of south-facing frontage, this home is light-filled all day, year-round.

Enter the apartment into a gracious foyer with custom millwork and cove lighting, which leads to a 25-foot-wide living room boasting 9-foot ceilings, floor-to-ceiling windows, solid oak floors, and a separate dining area.

The home features an exceptionally large eat-in kitchen custom-designed by Molteni with Blanco de Macael marble countertops and natural oak cabinetry, a Sub-Zero refrigerator/freezer, a Miele oven and dishwasher, a Gaggenau cooktop and Falmec extraction hood, as well as custom cove lighting and detailed millwork throughout.

A separate powder room with elegant polished-chrome Dornbracht fixtures and a well-appointed laundry closet with a side-by-side Miele washer and dryer are conveniently located off the entry foyer.

The south-facing primary bedroom features a walk-in closet and a luxurious en-suite bathroom with stone floors and a Kohler enameled cast-iron bathtub. This thoughtful residence has been customized with electronic shades in both the living room and bedroom.

Exquisitely crafted by the master architects of Foster + Partners, 551 West 21st Street features a private, gated drive court surrounded by a twenty-foot green wall and a dramatic, awe-inspiring 34-foot, double-height lobby with a grand chandelier. Additional amenities include superb service via a 24-hour attended lobby and concierge, porter and valet services, a state-of-the-art fitness center with his and her spa, yoga room, residents' lounge, playroom, bike storage, a live-in super, and a dedicated, separate service entrance.

This home is ideally located between the Hudson River Park and The Highline Park in the heart of West Chelsea, equidistant between Hudson Yards to the North and the vibrant Meatpacking District to the South, a neighborhood comprised of hundreds of the world’s leading Contemporary Art Galleries, unique boutiques, restaurants, and moments from The New Whitney Museum, Faena Hotel and Spa and so much more.

## Sales Evidence

### How this price compares

The median closed price for comparable condo one-bedroom sales in Chelsea is $1,500,000, based on 147 sales between September 2024 and July 2026. This home is asking $2,150,000, $650,000 above that median. The middle half of those sales closed between $1,132,500 and $1,907,500.

- **Median closed price**: $1,500,000
- **Middle half**: $1,132,500 – $1,907,500
- **Based on**: 147 condo one-bedroom sales in Chelsea
- **Period**: September 2024 – July 2026
- **Median $/ft²**: $1,788/ft²

Across the 127 of these sales with a published asking price, the median closed at 96.2% of what it originally asked. 85% of them closed below the original ask.

This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Chelsea instead.

### How these sales were negotiated

- **Sold vs original ask**: 96.2% of the original ask
- **Closed below ask**: 85% of 127 sales
- **Listed → in contract**: 79 days (about 11 weeks)
- **In contract → closed**: 51 days (about 7 weeks)

Across the 127 of these sales with a published asking price, the median closed at 96.2% of what it originally asked. 85% of them closed below the original ask.

Half of these homes were in contract within 79 days (about 11 weeks) of coming to market, based on the 131 with a recorded listing date.

Once a deal was agreed, closing took a further 51 days (about 7 weeks), based on the 131 with both dates recorded.

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.

Based on 147 condo one-bedroom sales in Chelsea, September 2024 – July 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ.

### Price trend

Median sold price for condo and house one-bedroom sales in Chelsea, 2016 to 2026. The series is held to one bedroom count and one ownership type for the same reason: an unfiltered median tracks which apartments sold, not what they were worth.

| Year | Median sold price | Sales |
| --- | --- | --- |
| 2016 | $1,399,819 | 22 |
| 2017 | $1,300,000 | 76 |
| 2018 | $1,410,000 | 72 |
| 2019 | $1,300,000 | 55 |
| 2020 | $1,080,000 | 35 |
| 2021 | $1,454,250 | 144 |
| 2022 | $1,400,356 | 143 |
| 2023 | $1,191,353 | 92 |
| 2024 | $1,420,000 | 75 |
| 2025 | $1,500,000 | 98 |
| 2026 | $1,262,500 | 24 |

This building does not have enough sales with a recorded floor area to chart its own price per square foot, which is usual for a co-op. The series above follows comparable homes across Chelsea instead.

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.
