A Private Pricing Opinion — what your apartment at 450 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.
450 West End Avenue is a late-pre-war cooperative designed by Boak & Paris and built in 1930–31, at the very end of the boom, as the apartment-house era was closing and the Depression was reshaping what could be built. Buildings of this final pre-war moment tend to be among the best of their generation: they incorporate everything the 1920s had taught New York's architects about luxury apartment design, executed just before construction stopped. At nineteen stories (eighteen plus a penthouse, in the Landmarks Preservation Commission's count), 450 stands taller than most of its West End Avenue neighbors.
The Landmarks Preservation Commission classifies the design as Renaissance Revival, executed in brick with terra-cotta and cast-stone trim. The building sits inside the Riverside–West End Historic District Extension I.
The building has approximately 56 residences across nineteen stories; inspect individual plans and dimensions rather than deriving apartment size or availability from those totals. For buyers who want serious pre-war space and West End Avenue's quieter, more residential character a block from Riverside Park, 450 is a benchmark address — and a notably flexible one for the corridor, with a roof deck, an in-unit washer/dryer policy, and a pet-friendly board.
Architecture and unit composition
The approximately 56 apartments span 19 stories in the large, elegant layouts for which the building is known — high ceilings, hardwood floors, formal room separations, and the original architectural detail of 1931-era luxury design. The low unit count against the building's height is the structural sign of generous footprints: 450 was built for family-scale living at the top of the West End Avenue market.
West End Avenue exposures carry the avenue's light and residential calm; higher floors on the upper end of the nineteen-story building pick up open city outlooks and, on the right lines, distant river-direction views. Renovation condition varies across the unit mix, from preserved original detail to fully modernized interiors — and the building's in-unit washer/dryer policy and central-air allowance make full modernizations practical.
Building operations
450 West End Avenue is a full-service pre-war cooperative with a 24-hour doorman, two attended elevators, a live-in superintendent, a common roof deck, a bike room, central laundry, and common storage. The cooperative is pet-friendly and permits in-unit washer/dryers. On the financial side, the board requires a 35% minimum down payment — financing up to 65% of the purchase price — and a transfer fee (flip tax) applies on resale. The conversion from rental to cooperative ownership dates to the late 1960s, placing 450 among the earlier West End Avenue conversions.

The latest available filing classified the facade as Unsafe — conditions requiring prompt corrective action. The owner must install any public protection the inspector specifies (a sidewalk shed, construction fence or structural netting, depending on the condition) and make the repairs. Review the subsequent filings, the repair status, and the building’s board and financial materials — we pull the repair scope and funding picture for you.
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 2025–30. 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.

What to know if you’re buying
This is a top-tier West End Avenue address. The 1931 late-pre-war vintage and large gracious layouts place 450 among the corridor's most prestigious buildings.
Pets, in-unit laundry and a roof deck. Pets are permitted, in-unit washer/dryers are permitted, and the roof deck is a genuine amenity.
Know the financial terms going in. Plan for a 35% minimum down payment and budget the resale transfer fee into your hold math.
Check current availability by line. The roughly 56-apartment count does not establish turnover or scarcity; compare active listings and dated transfers for the layouts you need.
What to know if you’re selling
Lead with the vintage and the flexibility. The late-pre-war Boak & Paris design and 450's standing as a benchmark West End address are the headline assets; the roof deck, pet policy, and washer/dryer allowance broaden the buyer pool.
Price to layout and condition. Large apartments price on their specific configuration and renovation level; comp against the most comparable in-building and corridor trades.
Closing timelines are co-op standard — generally 6–10 weeks from contract to closing.

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.
