910 Park Avenue is one of the architecturally most distinguished smaller-scale pre-war cooperatives on Park Avenue and a structurally distinctive Schwartz & Gross commission. Completed in 1924 — slightly earlier than the firm's 888 Park commission two blocks south — the building sits at the southwest corner of Park Avenue and East 80th Street and operates on a structurally distinctive two-apartments-per-floor configuration across its 14 stories, producing the 28-apartment intimate scale that defines the building's cooperative culture.
The architectural detail at the building's exterior is unusually refined for the Park Avenue cooperative tradition. The two-story rusticated limestone base, the two-story-high fluted pilasters flanking the bronze entrance doors, and the decorative bronze roofline together produce an architectural composition with detail-specification depth distinguishing 910 Park from peer pre-war Park Avenue cooperatives. Carter Horsley's CityRealty review documents the architectural specifications in substantive detail.
The 1957 cooperative conversion places 910 Park among the post-war cooperative conversions of the broader Park Avenue corridor; the building's deep institutional cooperative history has produced a building culture continuously refined for nearly seven decades.
The building's residential history sits at the institutional core of early-20th-century New York German-Jewish financial leadership. Carl M. Loeb — banker and founder of Loeb, Rhoades & Co. — was a documented resident. The Loeb wedding (his daughter's, hosted at Adolph Lewisohn's nearby 881 Park residence) drew guests including the Warburgs, Lehmans, Morgenthaus, and Strauses — the building's residential context positioned it at the center of the "Our Crowd" social network that defined a substantial share of early-20th-century New York Jewish financial leadership.
Architecture and unit composition
The 28 cooperative apartments distribute across the building's 14 stories at two apartments per floor — a structurally intimate configuration unusual on Park Avenue. Apartment scale is substantial. Documented Carter Horsley CityRealty review specifications include:
- A 7th-floor 4-bedroom apartment: 29-foot entrance gallery, 18-foot library, 29-foot living room with wood-burning fireplace, 16-foot dining room, breakfast room, and kitchen
- A 10S 2-bedroom apartment: 21-foot gallery, 19-foot library, 27-foot living room with wood-burning fireplace, 20-foot dining room, 20-foot kitchen
These room dimensions place 910 Park among the more substantial pre-war Park Avenue apartment configurations.
CityRealty assigns the building a rating of 76.
Building operations
910 Park operates as a full-service cooperative with a doorman and an elevator operator — the elevator-operator service is a structural feature uncommon in contemporary Park Avenue cooperative operations and reflects the building's institutional pre-war tradition. The building does not carry an on-site garage or a fitness center.
The building permits protruding through-wall air-conditioning installations — a specific operational policy that buyers planning apartment renovations should understand at the start of any prospective transaction.
The cooperative policy framework should be verified directly during due diligence; specific financing maximum, flip tax structure, pet policy, pied-à-terre allowance, and sublet duration limits are not publicly published in full.
What to know if you’re buying
The Schwartz & Gross architectural pedigree is structurally distinguishing. Among the firm's most architecturally detailed Park Avenue commissions; the two-story rusticated limestone base, fluted pilasters, and bronze roofline are real architectural specifications.
The 28-apartment two-per-floor configuration is structural. Among the more intimate Park Avenue cooperatives; the building culture is correspondingly institutional.
The room dimensions are substantial. Pre-war apartment scale at the upper end of the corridor's typical range.
The Park Avenue Historic District contributing-structure status is real institutional recognition.
Apartment renovation should be understood at the start. The building's policy permits protruding through-wall AC units; comprehensive HVAC system modifications should be evaluated against the building's specific approval framework.
Verify operational specifics during due diligence. Specific board approval framework, financing structure, sublet policies, current capital project pipeline, and the LL11 façade cycle on the 1924 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 architectural detail and the apartment scale. Schwartz & Gross's most architecturally detailed Park Avenue commission; substantial pre-war room dimensions.
The two-per-floor configuration is structurally distinguishing. A real architectural-credential marketing point.
Pricing requires apartment-level comparable analysis on a 28-unit base. Thin transaction inventory means each closing carries meaningful weight in the building's reference pricing.
Closing timelines are cooperative-standard.
