137 Duane Street — known as "Diamond Duane" — is a five-story cast-iron and masonry loft building steps from Duane Park, mid-block between Church Street and West Broadway in the heart of Tribeca. Its origins reach back to roughly 1864, and a major renovation and residential conversion in 2004 turned the upper floors into 19 full loft residences while retaining the fluted cast-iron columns and tall arched windows that define the era.
The proposition is authentic Tribeca loft living at boutique scale. The building sits inside the Tribeca West Historic District, so its exterior character is protected, and its lofts offer the high ceilings and large floorplates that command a premium in this market. For the buyer who wants a genuine landmarked loft near Duane Park rather than a glass tower, Diamond Duane is a rare, tightly held address.
Building operations
The condominium runs lean and loft-appropriate: keyed-elevator direct access, central air, on-site storage, and a live-in superintendent, with no doorman — the right service level for a five-story boutique loft building, and a meaningful factor in keeping common charges contained. Because the tax lot also holds several commercial units, comparables should isolate the 19 residential lofts rather than blend the two.
As a condominium, ownership is by deed: purchases are subject to the condominium's right of first refusal rather than board approval, and financing, pied-à-terre use, and subletting are generally more flexible than in a co-op. Confirm the current pet policy, common charges, real estate taxes, and any assessments at offer stage.
Recent sales
Condo pricing is read on a price-per-square-foot basis, and 137 Duane trades at premium Tribeca loft levels — an average of roughly $1,241/sf, with large full-floor lofts of up to approximately 5,500 square feet. With only 19 residential lofts and full-floor scale, resale volume is thin, with a small number of closings in an active year. When underwriting a purchase or a list price, isolate the residential lofts from the commercial units, and capture the floor, the ceiling height, the exposure, and renovation condition rather than relying on a neighborhood average. Genuinely variable financial figures should be confirmed at offer stage.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-00147-7509) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.
What to know if you’re buying
This is a condominium, so the path is a purchase application and the condominium's right of first refusal rather than a board interview — a more flexible process than a co-op on financing and use. Read the house rules on the points that matter to you, review the condominium's reserve and any planned capital work given the building's age, and confirm the split between residential and commercial units on the tax lot. The reasons to buy are the address and the architecture: a landmarked cast-iron loft near Duane Park with full-floor scale and true loft proportions.
What to know if you’re selling
The story is the loft itself and the landmarked Tribeca setting. The circa-1864 cast-iron origin, the 2004 conversion, the fluted columns and arched windows, and the full-floor scale sell to a specific buyer who wants an authentic Tribeca loft near Duane Park. Pricing is an apartment-specific exercise: floor, light, ceiling height, and condition drive the number more than any block average. We position the building's protected character and boutique loft service, isolate the residential comps from the commercial units, and benchmark against the right tier of Tribeca loft condominiums.
