This building is what a Loft Law legalization looks like when it is carried all the way through to a condominium. The original structure is a turn-of-the-century five-story commercial loft on Washington Street, a block of Hudson Square that spent a century in warehousing and printing and then spent a good part of the 1980s and 1990s occupied residentially without the paperwork to prove it. The Department of Finance carried the property in a mixed residential class through the 2000s. In June 2010 an Alteration Type 1 was filed to legalize the Interim Multiple Dwelling units on the second, fourth and fifth floors, to legalize residential use on the third, to add five stories, and to upgrade the construction class from Class 3 to Class 1-C. Three dwelling units became nine.
The five added stories are the whole economic story. The lot is 2,752 square feet — small — and the existing commercial building already carried more floor area than a residential envelope would allow. Because the parcel sits in the Special Tribeca Mixed Use District and outside any historic district, the vertical enlargement was achievable. Had this block fallen inside the Tribeca North Historic District a few streets south, a five-story addition would have been an entirely different conversation, and probably not this building.
Zakrzewski + Hyde Architects made the split legible rather than hiding it. The base is the original brick loft; above the fifth floor the addition is steel and concrete and reads as an addition. That is an honest way to handle the problem and it is why the building looks like two ideas stacked, because it is.
The project took a long time. Ownership changed hands during the process, the current sponsor entity took title in 2012, the offering plan was dated June 2017, sales launched in late 2020, and the declaration was recorded in January 2022 with closings running through 2022 and 2023. A first amendment reconfigured the unit mix from eight residential units to nine and withheld one from the initial offering. What emerged is a nine-residence condominium in which every home occupies an entire floor.
Architecture and unit composition
The floor-through plan is the reason to buy here. Units 2 through 5 fill the original loft floors at roughly 2,775 square feet each; Units 6 through 10 fill the added floors at roughly 1,960 square feet each. There are no shared corridors on residential floors, no interior neighbors, and light on all available exposures — the classic advantage of a narrow-lot loft conversion, and one that new construction at this price rarely delivers.
Outdoor space is distributed unevenly and it matters. Unit 6 takes a roughly 800-square-foot setback terrace on the roof of the fifth floor, which is the largest private outdoor allocation in the building and sits at the seam between the old structure and the addition. Units 9 and 10 carry small private roof terraces of roughly 226 and 242 square feet. A third terrace of roughly 760 square feet on the roof is a common recreational facility reserved to the residential owners. All of these are limited common elements, and the declaration governs their maintenance and alteration.
The top of the building has since changed shape. City records show a 2022 filing for interior renovation of a "9th and 10th floor penthouse unit," and the two unit lots have been deeded together. The two smallest floor-throughs at the top of the stack now function as a duplex penthouse, which reduces the effective residential count in the building even though the unit lots remain separate.
The lower floors read as loft — original brick, large fixed-pane glazing, high ceilings — and the upper floors read as new construction. Buyers should walk both halves of the building; they are different products at different price points inside one condominium.
Building operations
Nine residences carrying an attended lobby, a cellar fitness room, bike and cold storage, and a landscaped common roof terrace is a heavy service load for a small denominator. The building's operating budget is the document that matters, not the amenity list, and prospective buyers should read it alongside the reserve position rather than reasoning from the common-charge figure.
Two structural items deserve attention. First, the commercial unit at the base carries its own common-charge and tax allocation, and the sponsor conveyed it separately in 2024; the current allocation between the residential and commercial sections should be checked against the current budget. Second, ACRIS records an easement instrument against the parent lot from 2014, recorded during the development period. The offering plan separately discloses that a proposed cellar studio easement was deleted by the First Amendment. Any buyer's counsel should pull and read the recorded easement, because a small lot in a special district can carry light, air and access encumbrances that do not surface in a title summary.
Finally, this is a conversion of an 1900s structure with a modern superstructure on top, which means two different maintenance regimes in one building: masonry and window restoration below, curtain-wall and roofing systems above. The façade inspection cycle should be reviewed with that split in mind.
Policy framework
Ownership form: Condominium. Purchases close through a right of first refusal rather than a cooperative board approval.
Sponsor position and board control — read the plan. The offering plan's Special Risks section discloses that the sponsor retains the unconditional right to rent rather than sell units after consummation, that sponsor may control the board of managers for up to two years from the first unit closing, and that for up to five years the board may not make additions or alterations to the common elements, or assess for reserves beyond a stated threshold, without the sponsor's consent. Those restrictions run from the first closing, which occurred in 2022. A buyer should establish where in that timeline the building currently sits and whether the sponsor retains any unit.
Pied-à-terre, subletting, LLC, trust and foreign ownership: All permitted under the standard condominium framework, with LLC and trust ownership present in the recorded deeds.
Storage: Conveyed under a license agreement with no monthly fee, available only with a residence, per the offering plan. Confirm the license is properly assigned at closing.
Pets, financing ceiling and flip tax: None of the three is documented in the plan materials on file or in public records. Confirm all three with the managing agent.
Real estate taxes: No exemption of any kind appears on any unit lot in the FY2027 assessment roll. Underwrite full unabated taxes against the current bill.

The building launched sales in late 2020 and closed its residences across 2022 and 2023, with a small number of resales since. Nine units means same-building comparables are thin, and the building splits cleanly into two pricing tiers — the larger original-loft floors below and the smaller added floors above — with the terraced units and the combined top-floor duplex trading on their own logic.
The comparable set is Hudson Square and north Tribeca loft conversions of similar scale, not the amenity towers to the south or the new construction along the Hudson. The features that carry value here are the full-floor plan, the private outdoor allocations, and the absence of interior neighbors; the features that require underwriting are the small cost denominator, the two-regime façade, and the complete absence of any tax abatement. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
Ignore PLUTO's alteration data. The city's file shows no alteration year for this lot. Five of its ten stories were built after 2010. Any automated valuation or age-based analysis using that record will be wrong.
Know which half of the building you are in. Floors 2 through 5 are the original loft at roughly 2,775 square feet; floors 6 through 10 are the addition at roughly 1,960 square feet. Different sizes, different construction, different prices.
Read the outdoor-space allocations in the declaration. The terraces are limited common elements with specific maintenance and alteration rules, and they are distributed unevenly across the stack.
Pull the recorded easement. An easement instrument sits on the parent lot from 2014. Have counsel read it.
Establish the sponsor's position on the board. The plan's control and consent provisions run for two and five years from the first closing in 2022.
Underwrite full taxes. No abatement of any kind.
What to know if you’re selling
Sell the full floor. No interior neighbors, no shared residential corridors, light on every available exposure. That is the argument, and new construction at this size cannot make it.
Correct the city record up front. Buyers will pull data showing a 1900 building with no alterations. Explaining the Loft Law legalization and the 2010 vertical enlargement turns a data problem into a credibility advantage.
Price by tier. Original-loft floors and addition floors are separate comparable sets within one building. A building-wide average misprices both.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent.
