An 8,000-square-foot triplex in Tribeca has come to market for $25 million, and its most valuable feature cannot be moved, sold separately, or even touched. Painted directly onto an iron column, a structural beam and the ceiling is an original 1979 mural by Keith Haring, made when the artist was still a student. The loft sits at 260 West Broadway in the landmarked American Thread Building, an 1896 Renaissance Revival block. In the late 1970s the School of Visual Arts kept a student gallery on the building's lower floor, and Haring, newly arrived at the school, covered the raw interior with energetic black-and-white interlocking forms. He worked in an unlikely medium — a mixture of shoe polish and alcohol — which makes the mural's survival across nearly five decades all the more remarkable. When the school vacated the space in the early 1980s and it became a restaurant, the work was hidden behind wallboard, accidentally preserved for decades until previous owners uncovered it in 2007 and found it largely intact. The unsigned piece has since been authenticated by the Keith Haring Foundation. The current owner, Adam Zoia, chief executive of Glocap Tech, bought the loft in 2021 and carried out a two-year, floor-to-ceiling renovation designed around the mural, even building a bar in front of it as a physical buffer against curious guests. Because the painting is fused to the building's structure, any buyer inherits a permanent conservation duty along with the apartment. The listing, held by Compass, revives a familiar downtown legend: the same apartment has surfaced on the market before, including a 2021 outing at just under $8 million. At $25 million the asking price asks the market to put a number on a work that can never leave the room it was made for.
