510 Park Avenue is one of the most architecturally elegant and operationally flexible boutique Park Avenue cooperatives between 59th and 79th Streets. A few quietly substantial qualities give it one of the most underrated buyer profiles on the corridor. The first is its Starrett Brothers developer pedigree: the firm that built the Empire State Building (1931) and Stuyvesant Town (1947) connects 510 Park, through its broader 20th-century institutional construction footprint, to a real construction-quality lineage. The second is scale — 25 to 26 apartments across 15 floors yield full-floor and half-floor plates with 30- to 48-foot corner living rooms, formal dining rooms, wood-burning fireplaces, marble bathrooms, and private elevator landings, a configuration that places the building squarely in the Candela / Cross & Cross prewar tradition without the brand-name address. The third is policy flexibility: pied-à-terre ownership is permitted (a posture rare for Park Avenue cooperatives), pets are welcomed, financing of up to 80% is available on most units, and the boutique 25-unit scale keeps operations intimate.
The building sits between East 60th and East 61st Streets in Lenox Hill, immediately across the avenue from The Regency Hotel and just north of the Park Avenue commercial corridor where Trump Park Avenue (502 Park) anchors the 59th Street corner. The location is among the most central on Park Avenue — five minutes to Central Park, the Plaza, Madison Avenue retail, and the 59th Street subway hubs.
Architecture and unit composition
Built by Starrett Brothers — the construction firm that would later build the Empire State Building and Stuyvesant Town — and designed by F.H. Dewey & Company, 510 Park Avenue is a boutique 15-story prewar with a two-story limestone base, light-beige brick facade, canopied entrance with bronze doors, and an "impressive lobby." The architectural posture is restrained relative to the more flamboyant Candela / Cross & Cross 1925–1930 cycle, but the structural identity of the building — full-floor and half-floor apartments with private elevator landings, generous corner living rooms, wood-burning fireplaces — places it firmly within the trophy prewar tradition.
Several full-floor apartments span approximately 5,000 square feet with 4 to 5 bedrooms en suite. Notable interior renovations include work by interior designer Tony Ingrao; one apartment features wood paneling imported from a European castle, complete with wine cellar and humidor. Most apartments carry central air conditioning, though some still rely on the original-vintage configuration with protruding window units.
Architectural records describe 510 Park a "pleasant 15-story building" with a "very impressive lobby" and "superb location." The canopied entrance with attractive bronze doors carries the building's exterior identity at the sidewalk.
Building operations
510 Park operates as a full-service Lenox Hill cooperative with the following operational baseline:
- 24-hour doorman and attended lobby
- Live-in superintendent (resident manager)
- Fitness center on site
- Bicycle room
- Dedicated resident storage (transfers with the apartment)
- Central air conditioning in most units
- No on-site garage; no roof deck; no broader health-club infrastructure
The building's operational posture is deliberately restrained — boutique 25-unit prewar cooperatives at this scale historically prioritize white-glove service and discretion over amenity-maximalism. The fitness center, bicycle room, and resident storage represent the baseline modern-amenity layer.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01374-0037) 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 selling
Marketing should emphasize the policy flexibility. Permitted pied-à-terre and 80% financing on most units are structural advantages over peer Park Avenue cooperative inventory.
The Starrett Brothers / F.H. Dewey architect-developer credential is real institutional context. Both names connect to substantial 20th-century New York construction history.
The boutique 25-unit scale supports premium positioning. Full-floor and half-floor plates with private elevator landings are the building's structural identity.
Pricing should reference recent comparable closings. Apartment-line-specific comparables should anchor positioning; the small unit count means individual closings move building-wide pricing benchmarks.
Closing timelines are cooperative-standard.
