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.

Facade safety — Local Law 11
The facade passed its last inspection with no required repairs — nothing to budget for here, and no facade assessment on the horizon for roughly five years.

Transaction cadence at 799 Park tracks its roughly 74-to-78-unit scale — a steady but moderate stream of activity in a normal year. Pricing reflects prime Park Avenue post-war values: generally more accessible per square foot than the pre-war co-op tier nearby, with premiums for higher floors, open exposures, the 74th Street corner line, and renovated condition.
With variation by floor, exposure, and condition, building-wide averages are of limited use; a current apartment-level comparable analysis is the right tool for pricing any individual home.
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.
