A Private Pricing Opinion — what your apartment at 799 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.
799 Park Avenue is a clean example of a particular and often-underrated tier of Park Avenue inventory: the post-war white-brick cooperative. Completed in 1961 to designs by H.I. Feldman for the Kimmel Brothers, it occupies the northeast corner of Park Avenue and East 74th Street — a prime Lenox Hill address — and rises twenty-one stories, taller than its pre-war neighbors and engineered to deliver the open light and efficient layouts buyers of its era prized.
H.I. Feldman was among the most prolific architects of post-war residential Manhattan, with a portfolio that defined the white-brick idiom across the East Side and beyond. At 799, the formula is executed with more care than the type's reputation sometimes suggests: a white-brick body lifted on a polished black-granite base, with a canopied entrance that signals the full-service co-op within. The building replaced earlier low-rise structures on the site, part of the broad mid-century rebuilding that brought taller, modern apartment houses to Park Avenue's side-street corners.
The positioning is the point. 799 sits squarely in the prime 70s of Park Avenue, surrounded by the pre-war co-op tradition the avenue is famous for — but it offers a different product: higher floors, more glass, more light, a modern mechanical baseline, and a genuine amenity package, typically at per-square-foot pricing below the pre-war tier a few blocks in either direction. Central Park is two blocks west, the Lexington Avenue 6 is a block east, and the building's own garage, fitness center, and landscaped garden round out a daily-living case the pre-war stock rarely matches.
Architecture and unit composition
The building's roughly 74 to 78 apartments are distributed across twenty-one floors — a generous floor count that places many units well above the surrounding pre-war rooflines, capturing open city light and, on the higher floors, the long Park Avenue axis. Post-war planning is evident throughout: larger windows than pre-war stock, consistent ceiling heights, and rational, efficient layouts rather than the foyer-and-service-wing sequencing of the 1920s.
The unit mix runs to the one-, two-, and three-bedroom configurations characteristic of post-war Park Avenue co-ops, with corner apartments benefiting from two-exposure light at the 74th Street corner. Renovation state varies apartment to apartment; many units in buildings of this vintage have been comprehensively updated, and condition is best evaluated unit by unit.
Building operations
799 Park Avenue operates as a full-service post-war cooperative with a full-time doorman and elevator attendant, an on-site resident manager, a fitness center, a landscaped garden, a central laundry, bike storage, and an on-site parking garage (typically wait-listed). For a post-war co-op of this size, that is a deep amenity package, and it is a meaningful part of the building's value.
On policy, the building is comparatively flexible for prime Park Avenue: pets are permitted, pied-à-terre ownership is welcome, and the board allows financing up to 50%. A 3% flip tax is paid by the buyer on purchase. Board review follows prime Lenox Hill norms — expect a thorough financial package and an interview — but the openness to pieds-à-terre and pets widens the buyer pool relative to the avenue's stricter pre-war co-ops.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01409-0001) 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
The post-war white-brick format is the value play. Higher floors, more light, a modern mechanical baseline, and a real amenity set come at pricing typically below the pre-war Park Avenue tier nearby — a deliberate trade-off, not a compromise.
The policies are accommodating. Pied-à-terre ownership, pets, and 50% financing make this an easier prime-Park co-op to buy into than many of its pre-war neighbors; budget the buyer-paid 3% flip tax into your closing costs.
Floor altitude matters more here than at pre-war peers. With twenty-one stories, the difference between low and high floors — in light, view, and the open Park Avenue axis — is substantial.
The amenities are a genuine draw. A fitness center, garden, and garage are scarce in prime-Park co-op stock.
What to know if you’re selling
Lead with the address, the light, and the amenities. A prime Park Avenue / East 74th Street corner co-op with post-war floor heights, open exposures, a fitness center, garden, and garage is a clear, marketable proposition.
Foreground the friendly rules. Pied-à-terre acceptance, pets, and 50% financing broaden the buyer pool — emphasize them.
Position against pre-war honestly. Frame the value as modern construction, light, and amenities at a more accessible price point than the pre-war tier — that is the buyer's actual decision.
Floor and exposure drive the comp set. In a tall post-war building, altitude and light are the primary differentiators among comparable apartments.

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.
