510 Park Avenue is one of the most architecturally elegant and operationally flexible boutique Park Avenue cooperatives between 59th and 79th Streets. The building's structural identity rests on three features that together produce one of the most underrated buyer profiles on the corridor.
First, the Starrett Brothers developer pedigree. Starrett Brothers built the Empire State Building (1931) and Stuyvesant Town (1947) — the firm's broader 20th-century institutional construction footprint connects 510 Park to a real construction-quality lineage. Second, the scale: 25 to 26 apartments distributed across 15 floors produces 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 — the configuration profile that places the building in the Candela / Cross & Cross prewar tradition without the brand-name address. Third, the policy flexibility: pied-à-terre 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 produces operational intimacy.
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.
Carter Horsley's CityRealty review (December 23, 2011) calls 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.

What to know if you’re buying
The boutique 25-unit scale is structurally distinguishing. Full-floor and half-floor plates with private elevator landings produce the configuration profile of trophy Park Avenue prewars at a smaller-scale operational footprint.
The Starrett Brothers developer pedigree is real. Construction quality lineage connects to the firm's later landmark work at the Empire State Building and Stuyvesant Town.
The 80% financing availability is uncommon on Park Avenue. Most peer cooperatives cap at 50%; however, verify apartment-line-specific financing rules at offer stage as some units require all-cash.
The pied-à-terre policy is materially advantageous. Permitted pied-à-terre on a Park Avenue prewar cooperative is structurally uncommon and supports flexible ownership use cases.
The 3% buyer-paid flip tax is meaningful at closing. Factor into all carrying-cost and net-proceeds calculations — on a $5 million purchase, $150,000 of additional buyer cost on top of mansion tax and standard closing costs.
Verify the air-conditioning configuration during walkthrough. Some units have full central AC; others rely on protruding window units. The configuration affects both operating cost and aesthetic identity.
The boutique 25-unit scale produces strong board posture and substantial liquidity requirements. Plan for full financial and personal-reference disclosure at application; substantial post-closing reserves typical of Park Avenue white-glove cooperatives apply.
Closing timelines are cooperative-standard. Plan for 6 to 10 weeks from contract through board approval to closing.
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.
