A Private Pricing Opinion — what your apartment at 812 Park 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.
812 Park Avenue is one of the avenue's quiet aristocrats — a J.E.R. Carpenter cooperative that won the AIA's New York Chapter gold medal as the best new residential building in the city the year it opened in 1927. That award is the building's signature fact, and it captures Carpenter's design philosophy precisely: 812 forgoes the ostentation of some of its contemporaries in favor of restraint and proportion. A limestone base sparingly decorated with carved swags gives way to beige-brick upper floors and a balustraded parapet — a tripartite neo-Renaissance composition that reads as confidence rather than display.
Carpenter built 812 as a cooperative for space. The building is a small cooperative whose specific apartment areas and floor configurations require unit-plan confirmation, with grand foyers leading to expansive living rooms with wood-burning fireplaces, formal dining rooms, and library nooks, finished in herringbone hardwood, custom millwork, and crown moldings. The low unit count against fourteen stories does not establish interior apartment size, floor-through layouts or frontage. For that buyer today, 812 offers architectural distinction, a tightly held shareholder community, and Lenox Hill Park Avenue positioning at the corner of 75th Street.
Architecture and unit composition
Confirm the residence's interior area, floor allocation and any duplex connections from approved unit plans rather than the building's unit-to-floor ratio. Carpenter's pre-war signatures run throughout: high principal-room ceilings, formal entry galleries, wood-burning fireplaces, gracious room separations, and the service infrastructure of 1927-era luxury design. Park Avenue exposures look across the avenue's planted median; side-street exposures off East 75th Street deliver cross-street light. Measure frontage and exposures for the specific apartment; the unit-to-floor ratio does not establish either.
Building operations
812 Park Avenue is run as a full-service, white-glove pre-war cooperative, with a staff of roughly 17 — 24-hour doormen, a live-in superintendent, and a resident manager. On-site amenities include a landscaped 32-foot-wide central courtyard garden, a fitness center, private storage, a bike room, and central laundry. The cooperative permits pets (cats and dogs), allows up to 30% financing, and charges a 2% flip tax paid by the buyer at closing. The low unit count, weighted toward large-format residences, produces a small, tightly held shareholder community with the institutional density to match a tier-one Park Avenue building.

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.

What to know if you’re buying
Confirm the apartment plan. Verify interior area, floor allocation and fireplace operation for the specific residence; building scale alone does not establish full-floor layouts.
The economics are documented. Up to 30% financing and a 2% buyer-paid flip tax are concrete, knowable terms; pets are permitted.
It's a tightly held membership. The low unit count and long holding periods mean inventory is scarce and acquisition is opportunistic.
Confirm the board's current requirements. Maximum financing is 30% of the purchase price; confirm the board's liquidity, ownership and occupancy requirements from the governing documents and application instructions.
What to know if you’re selling
Lead with the gold medal and the Carpenter pedigree. The 1927 AIA New York Chapter award and Carpenter's authorship are rare, specific, and highly marketable.
Configuration is the pricing driver. Full-floor, terrace, and large-format residences price on distinct logics; comp against the most genuinely comparable in-building and tier-one Park Avenue trades.
The amenity story is unusually deep for the scale. A landscaped courtyard garden, fitness center, and a 17-person staff are differentiators against the boutique co-ops nearby.
Closing timelines are co-op standard — generally 6–10 weeks from contract to closing, with rigorous board review.

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.
