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, boutique co-op of large-format residences — many of them full-floor — 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. That low unit count against a fourteen-story building is the structural sign of generous living: 812 was conceived for buyers who wanted house-scale apartments inside a full-service Park Avenue building. 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
The residences are principally large-format — full-floor and near-full-floor homes with the internal volume and floor separations that distinguish them from single-level apartments. 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. The low unit-to-floor ratio means each apartment commands substantial frontage.
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.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01389-0038) 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 on co-ops is not officially recorded, figures shown are approximate.
What to know if you’re buying
Large-format living is the building's identity. Full-floor and near-full-floor homes with wood-burning fireplaces — house-scale Park Avenue space inside a full-service building.
The economics are buyer-friendly by Park Avenue standards. Up to 30% financing and a 2% buyer-paid flip tax are concrete, knowable terms; pets are permitted, which is not universal on the avenue.
It's a tightly held membership. The low unit count and long holding periods mean inventory is scarce and acquisition is opportunistic.
Board approval follows tier-one Park Avenue norms. A strong financial profile, professional standing, and primary-residence intent are central to a successful package.
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.
