129 West 20th Street — The Chelsea Quarter — is a boutique loft condominium in central Chelsea, on the block between Sixth and Seventh Avenues. Built as an early-20th-century masonry loft building and converted to condominium around the turn of the millennium, it offers 15 loft-style residences in a genuinely intimate seven-story building, on one of Chelsea's most convenient corridors near the neighborhood's galleries, shopping, and transit.
What buyers respond to here is the loft character at a boutique scale. The residences carry the proportions of a converted loft building — spacious layouts, large windows, high ceilings, and wide-plank oak floors — updated with the conveniences buyers expect, including in-unit washer/dryers and central air. With only 15 apartments, the building is low-density and quiet, and the conversion delivered lofts that read as real homes rather than raw space. It is a well-located, well-judged Chelsea loft building rather than a large development.
The building is for buyers who want an authentic, updated Chelsea loft in a boutique condominium on a central block.
Architecture and unit composition
129 West 20th Street is a seven-story early-20th-century masonry loft building, converted to condominium use around 1999–2000. The building reads as a classic Chelsea loft structure on its block — solid, understated, and human-scaled rather than a glass tower.
Inside, the 15 residences are loft-style condominium homes with the open proportions of the original building: spacious layouts, large windows, high ceilings, and wide-plank oak floors, updated in the conversion with in-unit washer/dryers, central air, and walk-in closets. A commercial unit occupies part of the ground level. With so few residences, the specific floor, exposure, and layout of each home drive its value, and the loft geometry gives the better units a genuine sense of scale.
Building operations
129 West 20th Street operates as a boutique loft condominium with an elevator and the practical services appropriate to a 15-residence building. That is a sensible scale — the essentials of a well-run condominium without the overhead of a large tower. Common charges reflect the modest staffing and the converted-loft envelope; buyers should model the full monthly carry and review reserves and any capital history during due diligence, as is prudent for an early-20th-century loft building converted around the turn of the millennium.
Recent sales
As a condominium, 129 West 20th Street prices on a price-per-square-foot basis, with floor, exposure, loft proportions, outdoor space, and condition supporting value. Turnover is light for a boutique building of this size; both resale and owner-rental activity occur, but it is an ownership condominium, not a rental building. Apartment-level context — floor, exposure, layout, and condition — drives pricing more than any building average, and the loft character and the central Chelsea location support pricing for residences that present well.

What to know if you’re buying
Loft character is the draw. Spacious layouts, high ceilings, large windows, and wide-plank floors define the residences — the loft proportions are the differentiator.
Modern conveniences are built in. In-unit washer/dryers, central air, and walk-in closets came with the conversion — loft space without the compromises of raw loft living.
This is a boutique building. Just 15 residences in a seven-story building — low-density and quiet on a central Chelsea block.
Condo flexibility is real. Pied-à-terre, subletting, foreign buyers, and LLC/trust ownership are permitted under the declaration; closings run on condo timelines.
Mansion tax thresholds apply. At this building's pricing, the $1M and $2M cliffs can be in play. Run pricing through the Mansion Tax Calculator.
Variable board financial policy — confirm at offer stage. Financing percentages and any sublet terms specific to your situation should be confirmed in writing before you commit.
What to know if you’re selling
Lead with the loft. The proportions, ceilings, and light are the story; marketing should foreground the space and the updated conveniences.
Pricing requires apartment-level comps. With 15 residences, floor, exposure, outdoor space, and condition all move the number.
Present the light and the scale. Photography that reads the ceiling heights, the windows, and the wide-plank floors supports price.
