A Private Pricing Opinion — what your apartment at 670 West End Avenue would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
670 West End Avenue is a premier pre-war cooperative by George & Edward Blum, the brothers whose ornamental invention — terra-cotta, patterned brickwork, and stylized decorative motifs — set their buildings apart from the standard avenue stock of the 1910s and 1920s. Completed in 1926 at the corner of West 93rd Street and converted to cooperative ownership in 1969, the building carries the Blum signature outside and a restored lobby within, and it sits on one of West End Avenue's most desirable upper stretches.
The reason buyers gravitate to it, though, is the combination of pre-war architecture and a genuinely full-service operation. This is a 100%-owned co-op with a 24-hour doorman, a live-in superintendent, a recently renovated children's playroom, a bicycle room, central laundry, and private storage that transfers with the apartment — plus a landscaped roof deck with an herb garden, the kind of shared outdoor amenity that is scarce in the pre-war stock and a real draw on a corner this high above the avenue. For a buyer who wants pre-war room scale, a staffed lobby, a playroom downstairs, and a roof deck upstairs, 670 is a complete package.
The location anchors the case. The building is steps from Riverside Park and the Hudson greenway to the west, a short walk to Central Park to the east, and close to the 1/2/3 trains, the Broadway markets and restaurants, and the neighborhood's tennis courts.
Architecture and unit composition
The roughly 95 apartments span 16 stories. As a Blum building, the exterior rewards a close look — the firm's hallmark was ornament that reads as distinctly its own rather than off-the-shelf classical detailing — and the interiors deliver the pre-war essentials: high ceilings, hardwood floors, gracious entry foyers in the larger homes, and the solid masonry construction of the period. Layouts run from one- and two-bedroom homes through larger classic apartments.
Higher floors and corner exposures carry the building's light premium, with some upper homes capturing open western light over the low-rise frontage toward Riverside Park and the river. Condition varies apartment by apartment with individual renovation history, as in any building of this age.
Building operations
670 West End Avenue runs as a full-service pre-war cooperative. The staffing model centers on a 24-hour doorman and a live-in resident superintendent, with a recently renovated playroom, a bicycle room, central laundry, and private storage that conveys with each apartment. The standout shared amenity is the landscaped roof deck with its herb garden — a planted, furnished common space with open sky and neighborhood outlook that few pre-war buildings on the avenue can match.
As an established, 100%-owned cooperative, the building operates a standard board-approval process for purchases. Confirm the exact adopted LPC designation and applicable permit scope for this parcel before planning exterior work, alongside required cooperative approval.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. A filed Safe grade is not a guarantee of current condition: owners still maintain the facade and, where required, observe parapets each year. Future inspection timing (Local Law 49 of 2025 changed the cycle framework from October 1, 2026), repair and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Market read. Most recent trades (2025) cleared a median $1,050/sf (floor-adjusted) across 2 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 1.1% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
This is a board-approved cooperative purchase — expect a full board package, financial review, and interview. The building's appeal is specific: a Blum-designed pre-war with a restored lobby, a renovated playroom, transferable storage, and a landscaped roof deck, on a prime corner steps from Riverside Park. Run the financing math early, since co-op boards set financing limits and post-closing liquidity expectations. If you plan facade-affecting renovation, factor in the landmarks review that applies on top of board approval. We help buyers read the building's financials, benchmark the asking price, and prepare a complete board package.
What to know if you’re selling
The selling story is architecture plus amenity. Lead with the Blum pedigree and restored lobby, then with the amenities residents actually use — the renovated playroom, the bike room, the storage that transfers with the home, and the landscaped roof deck — and with the Riverside Park and West 93rd Street position. Price to the building's own recent closings and the comparable upper-West-End pre-war co-ops; the larger high-floor homes carry their own premium and reward careful positioning. Closing timelines are co-op standard, roughly six to ten weeks from contract through a normal board process.

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. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
