Construction is finally nearing completion on 172 Duane Park, a four-story addition stacked atop an existing two-story building at 172 Duane Street in Tribeca, more than a decade after work first broke ground. Ground-floor construction is still underway behind a sidewalk shed, but the structure's upper floors appear largely finished after years of fits and starts.
The project, reported by New York YIMBY, sits between Greenwich and Hudson Streets, directly across from Duane Park itself. The addition is expected to span more than 20,000 square feet once finished, with the new floors set back from street level inside a metal framework topped by a glass roof. The outlet reports that the original open-air arches, gates, and glass brick wall on the existing structure were left untouched during the renovation.
Developer Anthony Coll is behind the project, having borrowed $14.5 million from Castellan Capital to fund it, according to the same report. YIMBY describes the building as containing two units with a private rooftop terrace once it's done.
A Timeline Measured in Years, Not Months
Construction on the site began back in 2015, and the structure topped out somewhere between 2020 and early 2021, per YIMBY's reporting. But the project barely moved for years afterward. The station's report notes that scaffolding covering the new upper levels only began coming down in 2025, a visible sign of life after a long quiet stretch.
That dormancy didn't go unnoticed locally. Tribeca Citizen reported in September 2025 that the site had been under construction since 2015 and had sat dormant for at least six years. Expectations for a finish line have slipped repeatedly: back in July 2023, Tribeca Citizen reported that a source associated with the owner said construction would be done in six months. That timeline came and went, and now YIMBY expects construction to wrap sometime in early 2027 — itself a forecast rather than a confirmed completion date, since ground-floor work remained visibly unfinished as of its November 2026 report.
Conflicting Accounts of What's Actually Inside
Exactly what the finished building will contain depends on which account you read. YIMBY's recent report describes just two units total, plus the rooftop terrace. But Tribeca Citizen's account of a 2023 occupancy list tied to building permits described something considerably denser: two apartments on each of floors three through six, in addition to the roof terrace. That same 2023 list reportedly also showed plans for an apparel and display studio on the first floor, with offices planned for the mezzanine and second floor.
Those two versions of the building's layout don't line up, and the available reporting doesn't resolve which one reflects what's actually being built. It's possible plans changed somewhere along the project's long and halting timeline, but neither outlet's account definitively settles the question of a final approved unit count.
What is clear is that after more than a decade of stop-and-start work, a corner of Tribeca steeped in the neighborhood's industrial-loft history is finally approaching its next chapter. Whether early 2027 actually marks the finish line, as YIMBY now expects, will depend on how quickly crews can wrap up the ground floor still hidden behind scaffolding.
