West 24th Street between Sixth and Seventh is a working loft block that never became a historic district and never became a tower corridor. It sat in an M1 manufacturing zone for the whole postwar period, which is exactly why the buildings on it are still the buildings on it — and why the residential conversions that happened here in the early 2000s each had to solve the zoning problem in their own way.
The Glassworks solved it by alteration application rather than by loft law. The building was in single ownership from 1974 through 1996 and passed to The Glassworks LLC in 2000. An Alteration Type 1 was filed that November for a seven-story building already carrying a residential occupancy; the condominium declaration was recorded in August 2003; and the first three residences closed in September 2003 with the fourth following in October. In 2005 a second Alteration Type 1 — a no-work filing — converted the second and fourth floor offices from Use Group 6B to apartments and studios under Use Groups 2 and 9. There is no Loft Board file, no interim multiple dwelling registration, and no joint living-work quarters certification. That is worth stating clearly because loft buildings of this profile in this part of Chelsea very often do carry one of those, and the diligence questions are different when they do.
The result is a seven-unit condominium in which only four unit lots are residential. The ground floor is retail. The second and fourth floors are commercial condominium units — occupied residentially since 2005 under the amended use groups, and traded as such, but still classified, assessed and financed as commercial. Buyers who see seven floors and assume seven apartments, or who look at a second- or fourth-floor unit without checking its lot classification, are underwriting the wrong asset. Lenders treat a commercial condominium unit differently from a residential one, and so does the Department of Finance.
The second thing that changed under this building recently has nothing to do with the building at all. In August 2025 the City Council approved the Midtown South Mixed-Use Plan, which mapped M1-8A paired with R11 and a new Special Midtown South Mixed-Use District over 42 blocks bounded roughly by 40th Street, Fifth Avenue, 23rd Street and Ninth Avenue. This block is inside it. Residential use went from a constrained non-conforming position to a district that permits residential development at 15.0 FAR. The Glassworks is built at 7.69. The building's own residents gain nothing directly from that, but everything around them — the low-rise loft buildings that currently give the block its light and its scale — is now worth substantially more as a development site than it was two years ago. That is the single most important forward-looking fact on this block, and it cuts both ways: it supports land value, and it puts light and air at risk over a long horizon.
Architecture and unit composition
The building is roughly 36 feet wide and 99 feet deep on an irregular lot, which produces a floor plate large enough for a genuine full-floor loft with real width — an unusual proportion for a mid-block Chelsea building, where 25-foot frontages are the norm. Every residence runs front to back with southern exposure across the street elevation, and the interior column line was modified under a 2005 structural filing that removed a column and replaced it with new steel framing, which is why the plans open the way they do.
The interior vocabulary is the loft vocabulary: high ceilings, exposed brick, exposed original wood joists, fireplaces and in-unit laundry, per listing records. A common roof deck sits at the top; the penthouse residence occupies the seventh floor. The masonry front was restored under an exterior job filed in 2008, with a sidewalk shed and full pipe scaffold — the last major façade cycle of record.
The residential units are large. Roughly 10,850 square feet of residential area across four homes is an average well above 2,500 square feet, which is a scale of apartment Chelsea produces almost exclusively in loft conversions and almost never in new construction at comparable pricing.
Building operations
Seven owners, four of them residential, one elevator, no staff. Common charges here fund insurance, the elevator, water and sewer, the roof deck and façade reserves. There is no doorman payroll and no amenity program, which keeps monthlies low relative to the corridor's new-development condominiums and means the building's financial resilience is entirely a function of its reserve.
Governance carries the same asymmetry as the unit-lot structure. Three of seven units are commercial, including the retail base. A retail owner's priorities on storefront, sidewalk and façade spending are not a residential owner's, and in a seven-unit condominium the allocation of common expense between the two groups is a term to read rather than assume. Ask specifically how the common interest is split and whether the commercial units bear a proportionate share of façade, roof and elevator capital.
Local Law 97
This building is below the 25,000 sq ft threshold at which LL97 emissions caps apply. No regulatory capital pressure from this law specifically, current or 2030.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.

Recent sales
The Glassworks trades as Chelsea loft product: priced on floor plate, ceiling height and the rarity of a genuine full-floor home rather than on services or new-construction finish. Against amenitized new development in the same corridor, buildings like this one price at a discount per square foot and hold their buyers on layout — a 2,500-square-foot floor-through with light on the street elevation is not a product the corridor's new towers make.
Two structural features shape pricing inside the building. The first is the unit-lot classification: a commercially classified unit on the second or fourth floor is not directly comparable to a residentially classified unit on the third, fifth, sixth or penthouse floor, even where the physical space is similar, because financing terms and tax treatment differ. The second is the tax posture. There is no abatement on any residential unit and nothing to burn off, so the carrying number a buyer sees at closing is the carrying number, subject only to assessment growth. Index any market comparison to the last complete year; in a four-residence condominium, a partial year is not a data set.

What to know if you’re buying
Confirm the lot classification of the specific unit you are buying. Lots 1203, 1205, 1206 and 1207 are residential condominium units. Lots 1201, 1202 and 1204 are commercial condominium units on the Department of Finance roll. If you are looking at the second or fourth floor, your lender, your tax bill and your title work will all treat it as commercial regardless of how it is being lived in. Get the answer from the deed and the unit-lot schedule, not from a floor plan.
Ask for the current certificate of occupancy. The open record shows temporary certificates renewed to August 2015 on both alteration applications. That may be a records artifact, but it is a five-minute question for the managing agent and a real title issue if it is not.
Read the common-charge allocation between the residential and commercial groups. Three of seven units are non-residential. Four residential owners carrying a disproportionate share of a façade or elevator cycle is the failure mode in a building this size.
Understand what the 2025 rezoning did to the block. Residential FAR on this lot is now 15.0 against a built 7.69, and Mandatory Inclusionary Housing applies. The land under and around this building is now worth more as development site than it was, which supports value and, over a long horizon, threatens the low-rise context that gives the building its light.
