450 Washington Street

The building reads as two connected masses around a courtyard: 16 stories numbered on the Washington Street side and 11 on the Greenwich Street side, joined by glass-enclosed skywalks. There is no 13th floor. The refaced exterior — French limestone plaster with large windows — is deliberately quieter than the cast-iron and masonry vocabulary of Tribeca's historic core, and it is calibrated to Related's neighboring 70 Vestry rather than to the district's industrial past.

The 176 residences distribute as follows, per the plan's Schedule A: five terraced townhouses at grade (TH1 through TH5, from 722 to 2,179 interior square feet, each with a terrace); a dense band of studios through four-bedrooms on floors two through six, where the largest units run past 1,900 interior square feet with terraces above 350 square feet; a lower-density band of ten residences per floor on floors seven through eleven, including several large terraced homes over 2,000 interior square feet with terraces exceeding 1,000 square feet; five-residence floors at twelve, fourteen and fifteen; and four penthouses numbered PH1601 through PH1604, the largest at 2,411 interior square feet with 1,505 square feet of balcony and terrace.

Two patterns are worth carrying into a comparable analysis. First, the terrace inventory is unusually deep — over 17,000 square feet across the building, concentrated in the lower and mid floors and in the townhouses, which is the inverse of the usual new-development distribution. Second, the studio and one-bedroom stock is genuinely small: several studios sit in the 440 to 480 square foot range, and the one-bedrooms that traded in the low-$1 million range at launch were around 600 square feet. The building spans a very wide product range under one roof, and averaging across it produces numbers that describe nothing.

450 Washington operates as a full-service cooperative with a resident manager — the plan designates a resident manager's apartment on the second floor and funds it through the purchaser contributions described above. The amenity suite is contemporary rather than extensive: a residents' lounge, a private dining room, a fitness studio, a golf simulator, a children's play space, on-site parking, and a two-level roof deck on the 12th floor of the east building oriented to the Hudson River sunsets and, from the east side, back across the neighborhood. The landscaped courtyard functions as the building's real common space.

Ground-floor retail fronts Washington Street. The block sits a short walk from Hudson River Park, the Pier 25 and Pier 26 recreation piers, and the north Tribeca restaurant cluster along Greenwich and Hudson Streets.

The policy stack is the building's commercial argument and it is unusually permissive for a cooperative:

Purchase and sale approval: none in the cooperative sense. The sponsor structured the cond-op explicitly so that transfers run on condominium rules rather than through a board approval process. This is the single largest transactional difference between 450 Washington and the Tribeca co-op inventory.

LLC and entity purchases: permitted.

Subletting: permitted.

Pied-à-terre and part-time occupancy: permitted.

Maintenance: projected at $787.61 per share for the first year of cooperative operation and revised to $760.62 per share by the Fourth Amendment dated May 1, 2023. That works out to roughly $3.10 to $3.20 per interior square foot per month for typical interior residences and materially more for the large terraced units, whose share allocations reflect the exterior space. Ground rent under the land lease is carried inside maintenance, which is why the per-foot figure sits above what a fee-owned Tribeca co-op of similar vintage would charge — and why the maintenance line, not the purchase price, is where the ground lease shows up on a buyer's monthly.

Purchaser contributions at closing: the plan requires a Resident Manager Contribution and a Title Insurance Contribution from each purchaser, scaled to share allocation, aggregating roughly $1.505 million and $1.335 million respectively across the offering. Together they run about $284 per share. These are genuine closing costs and they should be modeled explicitly.

Rent regulation: one apartment carried rent-stabilized status when the plan was filed. Every other residence was offered vacant, which is why this reads as a new-development sellout rather than as a conventional occupied-building conversion.

Recent sales

Recent transfers at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026) cleared a median $2,468/sf (recorded) across 7 sales. Median listing discount 3.0% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00224-7504). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.

Start with the ground lease, not the floor plan. The land is owned by Ponte Equities and the cooperative's interest expires in 2105. Term, rent-reset mechanics, renewal rights and any purchase option are the facts that determine what you own.

Confirm financing early. Leasehold cooperatives are financeable but the lender pool is narrower than for condominiums, and terms differ. Have a lender who writes this structure lined up before contract.

Model the maintenance, not just the price. Ground rent sits inside maintenance. A per-square-foot maintenance figure above the fee-owned Tribeca norm is the structure showing up on your monthly statement, and it is the number that governs your carrying cost for as long as you own.

Budget the closing contributions. The Resident Manager and Title Insurance Contributions run roughly $284 per share combined. On a mid-size apartment that is a five-figure line item due at closing.

The permissions are the reason to be here. No board approval, LLC purchases, subletting and pied-à-terre use are all permitted. If any of those matter to you, this building does something the Tribeca co-op stock cannot.

Ceilings are around nine feet. This is a converted 2009 frame, not new construction. The volume is in floor area and glass, not height.

Explain the structure in the first showing. A buyer who understands the cond-op and the 2105 leasehold from the outset can price it. One who learns it from counsel in week three usually walks. Transparency here produces stronger outcomes, not weaker ones.

Price against the structure. Same-line comparables inside the building are the anchor. Fee-owned Tribeca condominium sales are context, not evidence, and using them as evidence will cost you months.

Market the permissions. No board approval, entity purchases permitted, subletting permitted, pied-à-terre permitted — that combination opens a buyer pool the surrounding co-op inventory is closed to, and it is worth stating explicitly in the marketing.

Terraces are the differentiator. Over 17,000 square feet of exterior space is distributed across the building, and the terraced lower and mid-floor residences are structurally different products from the interior stack. Photograph and price them as such.

Closings are fast. With no board approval process, the transaction runs on condominium timing.
