800 Park Avenue is among the most architecturally distinctive pre-war cooperatives on the Lenox Hill stretch of Park Avenue. Completed in 1925 by Electus D. Litchfield and Pliny Rogers, the 15-story building was constructed by Starrett Brothers — the firm responsible for the Empire State Building and a substantial share of New York's interwar institutional and residential construction. The 800 Park Avenue Corporation was incorporated in 1925; the building was sold as cooperative from inception.
Electus D. Litchfield (1872–1952) was the Brooklyn-born architect who served as president of the Municipal Art Society and chairman of the planning and zoning committee of The City Club. His New York apartment-house body of work is comparatively limited; 800 Park represents the architect's principal Park Avenue showcase. Pliny Rogers was Litchfield's partner on the commission. The architectural composition is neo-Renaissance executed in the full-floor planning idiom that defined the upper Park Avenue cooperative tradition.
The structural distinction at 800 Park is the 16-residence configuration with 12 full-floor apartments, 1 penthouse, and 2 maisonettes. The full-floor planning produces apartments with three-sided exposures on most floors — a structural feature supported by the landmark-protected low-rise neighboring buildings whose preservation guarantees the apartment-level light and air. Western windows reportedly catch glimpses of Central Park two blocks away.
The Park Avenue Historic District (LP-2547) designation in April 2014 placed 800 Park within the broader corridor's architectural-protection framework. The November 15, 2022 LPC presentation materials for the building document the active preservation review process applicable to exterior modifications.
Architecture and unit composition
The 16 cooperative apartments distribute across the building's 15 stories in 12 full-floor configurations, 1 penthouse, and 2 maisonettes. Apartment layouts carry the substantial pre-war Park Avenue dimensions characteristic of Litchfield & Rogers's 1925 design — three-sided exposures on most full-floor units, substantial ceiling heights, formal entry galleries, library-living combinations, and the staff-wing infrastructure characteristic of mid-1920s Park Avenue construction.
Unit 15 was listed in July 2024 at $10,950,000; the apartment had last closed in May 2008. Building average $/sf on recent transactions has run at approximately $2,467.
Building operations
800 Park operates as a full-service cooperative with full-time doorman and live-in resident manager. The amenity infrastructure includes an in-house fitness center and additional storage. The building does not carry an on-site garage or a roof deck.
The cooperative policy framework — 40 percent maximum financing, 2 percent buyer-paid flip tax, pet-friendly — supports a structurally specific buyer pool calibrated to the trophy pre-war Park Avenue cooperative tradition. Pied-à-terre and sublet specifics should be verified directly with management.

Facade safety — Local Law 11

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01389-0036) 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 Litchfield & Rogers architectural credential is structurally distinguishing. Among the architect's principal Park Avenue commissions; the full-floor planning idiom is consistent with the pre-war Park Avenue trophy tradition.
The 12-full-floor configuration is structural. Apartment-level exposures and proportions reflect 1925-vintage Park Avenue luxury construction.
The Park Avenue Historic District protection applies. Designated LP-2547 by the NYC LPC on April 29, 2014.
The 40 percent maximum financing is restrictive. Materially more demanding than typical Park Avenue cooperative norms; buyers should plan for the substantial cash requirement at closing.
Inventory turnover is meaningful given the 16-unit scale. Recent comparable analysis depends on small samples.
Verify operational specifics during due diligence. Specific board approval framework, sublet duration limits, current capital project pipeline, and the LL11 façade cycle on the 1925 vintage should be reviewed.
Closing timelines are cooperative-standard. Plan for 6–10 weeks from contract through board approval to closing.
What to know if you’re selling
Marketing should emphasize the Litchfield & Rogers credential and the full-floor configuration. Both are structural identity features.
Pricing requires apartment-level comparable analysis. Thin transaction inventory means each closing carries meaningful weight in the building's reference pricing.
Closing timelines are cooperative-standard.
