A Private Pricing Opinion — what your apartment at 510 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.
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, and canopied entrance with bronze doors. 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.
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.
Policy framework
Verified across Compass building documentation, with policy cross-confirmation:
- Financing maximum: Up to 80% on most units; some units require all-cash purchase (apartment-by-apartment variance — verify at offer stage)
- Flip tax: 3% of sale price, buyer-paid
- Pets: Permitted ("pet friendly")
- Pied-à-terre: Permitted (notable posture for a Park Avenue cooperative)
- In-unit washer/dryer: Verify per apartment line
- Subletting: Board approval required; standard coop bylaw restrictions
- Trust ownership: Subject to board approval
- LLC ownership: Not typical for cooperative ownership
- Foreign buyer: Possible with substantial board diligence
- Post-closing liquidity: Substantial reserves typical of Park Avenue white-glove cooperatives — 3x to 5x annual maintenance plus real-estate-tax customary; verify specific board threshold at application stage
- Board interview: Required; full financial and personal-reference disclosure
The combination of 80% financing availability on most units and permitted pied-à-terre is structurally uncommon among Park Avenue prewar cooperatives. Most peer cooperatives at this scale cap financing at 50% and either prohibit pied-à-terre or require primary-residence commitment.

Notable residents
The building has historically housed multiple board-member-tier finance and old-line New York family residents. No widely-reported celebrity sales surface in public press — a residency pattern consistent with boutique 25-unit Park Avenue cooperatives that maintain deliberate discretion. The Tony Ingrao-designed European-paneled apartment is the building's most-photographed interior.
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.

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.
