The American Thread Building at 260 West Broadway is among the earliest luxury condominium loft conversions in Tribeca and one of the most architecturally distinguished buildings in the broader corridor's late-19th-century commercial inventory. The building was constructed between 1894 and 1896 — plans filed July 1894 at a construction cost of $275,000 — as the Wool Exchange Building, in an effort to support New York City's wool trade and overtake Boston as the dominant U.S. wool-trading center. The original architect was William B. Tubby (William Bunker Tubby), the late-19th-century New York architect whose body of work includes consequential commercial and institutional commissions across the city.
The American Thread Company occupied the building from 1901 through 1964, anchoring the building's enduring popular name. The building was converted to condominium residential ownership in 1980–1981 by Rose Associates — among the very earliest luxury condominium conversions in Tribeca, well before the broader Tribeca conversion wave that the 1982 New York State Loft Law would subsequently catalyze.
The building's architectural distinctions are substantial. The Renaissance Revival exterior (with some Romanesque elements that the architectural press has at times conflated) is articulated by a curved corner facade, a three-story base with alternating stone and brick bands, bold voussoirs above the arched openings, and a two-story entrance vestibule with polished granite columns over a cascading granite stair. Period architectural press acclaimed the building at completion. Engineering Magazine: "a strong, plain design, admirably in keeping." New-York Daily Tribune: "The building itself is a triumph of architectural art."
Apartment configurations at the American Thread Building carry the architectural features of the 1894–1896 commercial original: ceiling heights up to 26 feet in some units, oversized arched windows characteristic of the Renaissance Revival facade, original cast-iron columns retained throughout many interiors, and exposed-brick walls. The rotunda penthouse atop the building includes a stained-glass oculus — one of the most architecturally distinguished apartment features in Tribeca.
The building's most famous individual apartment is the 8,000-square-foot triplex maisonette containing an original 1979 Keith Haring mural. The mural was painted by then-20-year-old Keith Haring before the building's conversion to residential use; it was rediscovered during a 2007 renovation. The apartment was listed at $13 million and sold at the $10 million asking price; a related rotunda penthouse was subsequently listed at $14.8 million.
For buyers, the American Thread Building represents a particular position in the Tribeca market: William B. Tubby architectural pedigree at one of his most architecturally distinguished commissions, the structural advantage of an early-1980s conversion vintage, the substantial apartment scale and 26-foot ceilings characteristic of the original wool exchange use, and the unique cultural register of the Keith Haring mural apartment.
Architecture and unit composition
The 52 condominium residences distribute across the building's 11 stories in configurations characteristic of the 1894–1896 commercial original. Apartment ceiling heights run up to 26 feet in select units; oversized arched windows define the apartment exposure; original cast-iron columns and exposed-brick walls are retained throughout many interiors. The rotunda penthouse occupies the top of the building with the stained-glass oculus as the apartment's defining architectural feature.
Building operations
The American Thread Building operates as a full-service condominium with 24-hour doorman, live-in superintendent, rooftop gym, landscaped roof deck, bicycle storage, and basement storage. The amenity program is consistent with the building's 1980–1981 conversion vintage and the early Tribeca condominium tradition.

What to know if you’re buying
The architectural pedigree is structurally distinguishing. William B. Tubby 1894–1896; Renaissance Revival; the Wool Exchange / American Thread Company commercial history.
The 1980–1981 conversion vintage is structural. Among the very earliest luxury condominium conversions in Tribeca; the deep conversion history produces a building culture continuously refined for over four decades.
The apartment scale is substantial. 26-foot ceilings in select units; oversized arched windows; original cast-iron columns and exposed-brick interiors.
National Register of Historic Places listing applies. Listed in 2005; broader Tribeca historic district context may also apply (verify against LPC designation).
Condominium financial mechanics apply. Right-of-first-refusal closings; typically 30–45 day pacing.
What to know if you’re selling
Marketing should emphasize the architectural pedigree, the early-conversion vintage, and the cultural register. William B. Tubby 1894–1896, the Wool Exchange / American Thread Company history, and the Keith Haring mural apartment provide structural marketing arguments.
Pricing requires apartment-level comparable analysis. The variation between standard floor-plate apartments and the architecturally distinguished penthouses, maisonette, and rotunda configurations produces meaningful pricing variation.
Closing timelines are condominium-fast. 30–45 days.
