935 Park Avenue is structurally distinguishing within the Carnegie Hill Park Avenue residential tradition for a specific architectural-pedigree reason: it is one of the very few Manhattan apartment houses designed by Sugarman, Hess & Berger — a firm whose body of work is significantly smaller than that of the dominant 1920s Park Avenue architects (Schwartz & Gross, J.E.R. Carpenter, Rosario Candela), but whose architectural detailing at 935 Park produces one of the most refined entrance compositions on the avenue. The two-story-high limestone fluted pilasters flanking the canopied entrance, the terra-cotta friezes at the third floor and at the top of the building, and the dark wood-paneled lobby together produce an architectural register that places 935 Park among the architecturally most detailed pre-war Carnegie Hill cooperatives.
The structural identity of the building rests on its 33-apartment two-per-floor configuration across 17 stories. The two-apartments-per-floor planning produces apartments with substantial floor plates and the cross-ventilation and dual-exposure conditions characteristic of the smaller-scale pre-war Park Avenue cooperative tradition. Within the Carnegie Hill corridor, 935 Park sits among the most intimately scaled pre-war cooperatives — comparable in apartment-count scale to 910 Park (Schwartz & Gross 1924; 28 apartments two-per-floor) directly across East 81st Street.
The 1961 cooperative conversion places 935 Park among the post-war conversions of the broader Carnegie Hill corridor.
Friends of the Upper East Side maintains an active building file documenting the building's Park Avenue Historic District contributing-structure status and the LPC review processes applicable to exterior modifications.
Architecture and unit composition
The 33 cooperative apartments distribute across the building's 17 stories at two apartments per floor across most of the building's height. Apartment-level features carry the pre-war Park Avenue layout discipline characteristic of 1923–1924 luxury construction: substantial ceiling heights, formal entry galleries, library-living combinations, formal dining configurations, and the staff-wing infrastructure characteristic of mid-1920s Park Avenue planning.
In-unit washer/dryer is permitted — a structural feature confirmed across public records and the cooperative's published documentation, and meaningful within the broader pre-war Park Avenue cooperative tradition where in-unit laundry is often prohibited.
has Unit 14B listed at $2,290,000 in 2025 (Listing ID 22058530). public records places recent average closings at approximately $1,867 per square foot — at the upper end of the Carnegie Hill pre-war cooperative range, reflecting the building's intimate scale, the Sugarman, Hess & Berger architectural pedigree, and the two-per-floor apartment configuration.
The dark wood-paneled lobby is the building's principal interior architectural feature and a structural identity asset.
Building operations
935 Park operates as a full-service cooperative with full-time doorman, live-in resident manager, and the institutional service infrastructure consistent with the trophy pre-war Carnegie Hill tradition. public records amenity inventory and public records page documentation place 935 Park in the upper tier of Carnegie Hill cooperative operational baselines.
The cooperative policy framework supports pet ownership and in-unit washer/dryer installation. Additional policy specifics (financing maximum, flip tax structure, pied-à-terre allowance, sublet duration limits) follow the typical white-glove Carnegie Hill cooperative pattern — likely 50 percent maximum financing and a 2 percent buyer-paid flip tax consistent with the building's neighborhood peers — but should be verified directly against current management documents during due diligence.

What to know if you’re buying
The Sugarman, Hess & Berger architectural pedigree is structurally distinguishing. Among the firm's most architecturally detailed Park Avenue commissions; the two-story limestone fluted pilasters, terra-cotta friezes, and dark wood-paneled lobby produce one of the most refined entrance compositions on Carnegie Hill Park Avenue.
The 33-apartment two-per-floor configuration is structural. Substantial floor plates with cross-ventilation and dual-exposure conditions; an institutional cooperative culture calibrated to the intimate scale.
The in-unit washer/dryer permission is meaningful. Materially more accommodating than typical pre-war Park Avenue cooperative norms.
The Park Avenue Historic District protection applies. Designated LP-2547 by the NYC LPC on April 29, 2014; the building is a contributing structure within the district.
Recent pricing positions 935 Park in the upper Carnegie Hill cooperative tier. Approximately $1,867 per square foot on recent public records-documented closings.
Verify operational specifics during due diligence. Specific board approval framework, financing structure, flip tax, sublet duration limits, current capital project pipeline, and the LL11 façade cycle on the 1924 vintage should be reviewed against current management documents.
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 Sugarman, Hess & Berger architectural credential and the architectural detailing. Both are real architectural-pedigree features that distinguish the building from peer Carnegie Hill cooperative inventory.
The two-per-floor configuration supports premium positioning. The substantial floor plates and dual-exposure conditions are real architectural assets.
The in-unit washer/dryer permission is a real marketing point. Materially more accommodating than typical peer cooperative inventory.
Pricing should reference recent comparable closings. The $1,867 per square foot The recorded average provides upper-tier reference; apartment-line-specific comparables should anchor positioning.
Closing timelines are cooperative-standard.
