Ten residences in a 1910 loft on the corner of Eleventh Avenue and West 20th Street, with two floors added on top and a gallery at the base. The building is small, and everything interesting about it is structural rather than decorative.
Start with what it was. Historical records place the Mint Products Company here in the 1910s, manufacturing Life Savers — which is where the building's recorded name comes from, and it is a recorded name: the condominium declaration filed in 2010 identifies the property as "120 Eleventh Ave, a/k/a Life Saver Lofts." For most of the century after, the building did what West Chelsea buildings did — light manufacturing, then galleries and studios, then offices. A communications agency owned and occupied it at the turn of the millennium.
That agency filed the conversion. The Alteration Type 1 went in on 24 April 2001 and describes exactly what happened: factory lofts on floors two through five become apartments, galleries take the first floor, and two more residential floors go on the roof. The first permit issued in November 2002. Work continued through 2008, 2009 and 2010. The condominium was declared in June 2010, the first temporary certificate of occupancy issued in September 2012, and the final certificate of occupancy — the one recording ten dwelling units — did not issue until 24 December 2018. Seventeen and a half years from filing to final sign-off. That is a long conversion by any standard, and a buyer should know it, because it explains why the building's records are more layered than a seven-story building's records usually are.
The zoning is the second structural fact. The alteration was filed in 2001, when West Chelsea was still zoned for manufacturing; the Special West Chelsea District and the C6-3 mapping that now governs this lot arrived with the 2005 rezoning that also produced the High Line. No Board of Standards and Appeals variance for this lot appears in the records available to us, and the residential work was not completed to a certificate of occupancy until seven years after the rezoning made residential use permitted here. We state the sequence rather than guessing at the mechanism; the DOB job file and the certificate of occupancy are the documents that settle it.
The third fact is the one most likely to affect a buyer's light, and it is recent. In 2024 the building's unused development rights were sold to the developer of the adjoining West 21st Street site, along with the easements that go with such a sale — and in October 2025 the building filed with DOB to infill seven lot-line windows. That sequence is set out in full below.
Architecture and unit composition
Seven stories on a lot of roughly 8,875 square feet, carrying about 40,200 gross square feet — approximately 32,200 residential and 8,000 commercial. The lot measures roughly 79 by 88 feet at the avenue corner.
The residential plan is two apartments per floor on floors two, three and four (the A and B lines), then four penthouse residences above, two of them running as duplexes across the sixth and seventh floors — the added stories. That top-of-building configuration is why the penthouse residences trade at a distinct level from the lower floors: they are the new-construction part of the building, with the terraces and the outlook that come with being above the original roofline.
Below the residences sit two commercial units. The larger retail unit is separately owned and separately financed — ACRIS records a $5.3 million financing against it in 2013 and an $8.0 million financing in 2019 — and a gallery has operated in the West 20th Street frontage. The second commercial unit was retained by the sponsor and is the unit from which the 2024 development-rights sale was made.
The building has had a real exterior programme. DOB records an exterior restoration project filed in 2021, heavy-duty sidewalk sheds in 2021 and 2022, pipe scaffold in 2022 and again in 2025, the re-opening of three masonry-blocked original windows in 2024, and the lot-line window infill filed in 2025. This is an actively maintained envelope, not a neglected one, but it is also an envelope that has been under scaffold repeatedly in recent years.
Building operations
Ten residential owners. There is no doorman and no amenity programme; this is a boutique loft condominium where the residences are the product and the operating budget is thin by design.
The denominator is the governing operational fact. Every capital item — the exterior restoration cycle, the roof over the added floors, the elevator, the boiler — divides ten ways among the residential owners plus whatever share the two commercial units bear. The recent exterior work under sidewalk sheds in 2021 and 2022 and scaffold in 2025 is the kind of programme that produces assessments in a building this size. Read the current budget, the reserve balance, and the minutes covering the exterior programme and the development-rights transaction before you underwrite the monthly.
Because the residences run two to a floor with the penthouse duplexes above, common circulation is minimal and the building operates closer to a small loft co-op than to a serviced condominium — with condominium governance, a right of first refusal rather than board approval, and none of the co-op financing constraints.
The 2024 development-rights sale and the lot-line windows
This is the most consequential thing in the building's recent record and it is not visible on any listing.
On 17 June 2024 a zoning-lot instrument was recorded against the sponsor-retained commercial unit by 550W21 Owner LLC. On 10 July 2024 four instruments recorded together: a development-rights transfer for $1,000,000 from Puissance Enterprises, LLC to 550W21 Owner LLC; easements recorded against both the retail unit and the condominium in favour of 550W21 Owner LLC; a declaration; and an agreement joined by the condominium under both its own name and "Lifesaver Lofts." A further declaration and agreement recorded in March 2025. 550W21 Owner LLC is the record owner of 540 West 21st Street, a twenty-story building on this same block whose rear lot line runs against this building's northern boundary.
Then, on 22 October 2025, the condominium filed with DOB for the infill of seven lot-line windows.
Read together, the sequence is straightforward and material: the building's unused floor area has been transferred to the adjoining West 21st Street development, the adjoining owner has taken the easements that permit it to build against this lot line, and seven windows that presently give light to residences here are being permanently closed. Two practical consequences follow for a buyer. First, the development rights are gone — no rooftop addition, no further enlargement, and no future windfall from selling air rights. Second, and more immediately, light and outlook in specific apartments will change, and the seven affected openings need to be identified against the specific unit under consideration.
Ask the managing agent for the recorded easement documents, the DOB filing for the window infill, and any board communication describing the consideration received and how it was applied. This is a ten-unit condominium; a $1,000,000 development-rights payment is a large number relative to the building's annual budget, and how it was treated — reserve, capital work, distribution — is worth knowing.
Policy framework
Ownership form: Condominium. Sale and lease pass through a right of first refusal rather than board approval — the standard condominium mechanic, and a meaningful advantage over the co-op alternatives in this corridor for buyers using trusts, entities or non-standard financing.
Common charges and utilities: Residential heat and hot water are funded through common charges under the recorded declaration structure; gas and electricity consumed within each residence are metered to the owner.
Pets, subletting and pied-à-terre use: Not published. The offering plan and its sixteen amendments are on file in The Roebling Research Library, but the copy on file is a scanned image without a usable text layer, and the house rules could not be read from it. Confirm each item with the managing agent at offer stage. As a condominium, the default posture on subletting and pied-à-terre use is permissive, but house rules can and do add notice periods, minimum lease terms and fees.
Landmark constraint: None. The lot is not designated and not in a historic district. Window replacement, rooftop equipment and facade work here require DOB approval only.
Real estate taxes: No abatement, no exemption, no burn-off. Underwrite from the current bill on the specific unit.

Recent sales
120 Eleventh Avenue prices as boutique West Chelsea loft-conversion product: full-floor-scale residences valued per square foot, with a clear premium at the penthouse level for the added floors, the terraces and the outlook. The comparable set is the gallery-district conversions and small new-development condominiums between Tenth and Eleventh Avenues in the West 20s — not the amenitised towers on the High Line, whose common charges and buyer pools sit elsewhere.
Two things shape underwriting. The first is the ten-unit denominator, which means the budget and the reserve matter more than the headline common charge. The second is that the building's turnover is genuinely thin — several residences have changed hands only once or twice since the 2010–2014 sellout — so pricing runs off line-specific and floor-specific analysis against neighbouring buildings rather than off an internal building average. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
Identify the seven lot-line windows before you bid. The 2025 infill filing is the single most important diligence item in this building. Which apartments lose openings, and on which elevation, changes value materially in a two-per-floor building.
Read the certificate of occupancy, not the marketing. The final certificate did not issue until December 2018, and the building operated on temporary certificates for six years before that. Confirm the current certificate is final and that the unit you are buying is on it as a dwelling unit.
The taxes are what they look like. No J-51, no 421-a, nothing phasing out. The current bill is the bill. That is unusual comfort in a Chelsea conversion and it is worth saying out loud.
Underwrite the ten-unit denominator against the exterior programme. Sidewalk sheds in 2021 and 2022, scaffold again in 2025, and an exterior restoration project on file. Ask what was spent, what remains, and what the reserve looks like after it.
The penthouses are a different product from the lower floors. Floors six and seven are 2001-designed new construction on a 1910 base. Compare them to new-development product on the avenue, and compare the lower-floor lofts to conversions — not to each other.
What to know if you’re selling
Lead with the recorded name and the industrial provenance. "Lifesaver Lofts" is in the condominium declaration itself, and the Life Savers manufacturing history is documented. That is a real story and it survives buyer scrutiny.
Get ahead of the lot-line windows. A buyer's counsel will find the 2024 easements and the 2025 DOB filing. Present them yourself, with the offsetting facts — the consideration received, and the fact that the affected openings were always lot-line windows with no protected light.
Document the capital work. The exterior restoration programme is a selling point when it is presented as completed work with invoices, and a red flag when a buyer discovers it as an open scaffold permit.
Price the corner exposure. Eleventh Avenue and West 20th Street is a corner site with two open street frontages in a market where most conversion product is mid-block. True Monthly Carrying Cost Calculator.
