950 Park Avenue is a J.E.R. Carpenter cooperative from 1921, and Carpenter is the architect who, more than any other, established the typology of the modern Park Avenue and Fifth Avenue luxury apartment building. The portfolio across the 1910s and 1920s — 580 Park, 625 Park, 635 Park, 950 Park, 825 Fifth, 907 Fifth, 988 Fifth, and additional commissions — remade both avenues into the residential corridor recognizable today. 950 Park sits at the front half of Carpenter's mature 1920s work.
The 1921 vintage is significant. It places 950 Park among the earlier Park Avenue luxury cooperatives, predating the broader 1925–1931 construction-cycle peak by several years. Apartments at this vintage retain the Carpenter floor-plate discipline — formal entry galleries, library-living combinations, primary-suite logic — while the building's age also distinguishes it from the later cohort.
The 29-apartment count over 14 stories is unusually low for a Carnegie Hill Park Avenue building. Most peers in the corridor carry 40–70+ apartments. The 29-unit configuration implies apartment dimensions materially larger than the typical Carnegie Hill Park Avenue cooperative — closer in scale to Carpenter's selective Fifth Avenue work than to the high-volume Park Avenue 1929 cohort.
The corner positioning at Park Avenue and East 82nd Street places 950 Park at the southern edge of Carnegie Hill — directly across the street from 940 Park Avenue (Blum brothers 1925) and within the dense pre-war Park Avenue cooperative inventory. The Metropolitan Museum is six blocks west on Fifth Avenue.
For buyers, 950 Park represents a particular tier of Carnegie Hill Park Avenue inventory: Carpenter authorship at the firm's mature 1921 work, 29-apartment scale producing larger-than-typical apartment configurations, southern Carnegie Hill positioning, and pricing materially below the Candela tier-one peak.
Architecture and unit composition
The 29 apartments span configurations weighted toward larger 3–5 BR and full-floor layouts across the 14 stories. The low apartment count relative to building floor area implies room counts and apartment dimensions materially larger than the typical pre-war Park Avenue cooperative.
Carpenter's 1921 signatures throughout: 10–11 foot ceilings in primary rooms, formal entry galleries, library-living room combinations, primary suites with substantial closet infrastructure, service wings characteristic of staffed 1920s service. The 1921 vintage represents Carpenter's mature apartment-design discipline before the construction-cycle peak.
Park Avenue-facing apartments on the western flank look across to the Park Avenue median plantings and the buildings on the avenue's west side. 82nd Street-facing apartments to the south have cross-street exposures with stable residential side-street views.
Building operations
950 Park Avenue operates as a full-service pre-war cooperative with full-time doorman, attended elevator, on-site superintendent, and private storage. The 29-apartment scale produces low operational density and limited annual turnover.
Specific policy details (financing posture, flip tax structure, sublet policy specifics, pied-à-terre allowance) should be confirmed directly with property management during due diligence. The board posture follows tier-one Carnegie Hill pre-war norms.

What to know if you’re buying
The Carpenter authorship is the architectural anchor. Buyers attentive to architectural pedigree should understand Carpenter's role in defining the Park Avenue / Fifth Avenue apartment-house form — 950 Park sits within that portfolio.
The 29-apartment scale is structural. Apartment dimensions and room counts materially exceed the typical Carnegie Hill Park Avenue cooperative.
The corner Park / 82nd positioning is structural. Directly across the street from 940 Park; immediate proximity to the Met Museum and the broader Carnegie Hill cooperative concentration.
Pricing is more accessible than Candela tier-one peers. 950 Park typically trades at materially more accessible per-square-foot pricing than the 1929–1931 Candela apex.
Confirm specific policies directly with management. Financing posture, flip tax structure, sublet specifics, and pied-à-terre allowance should be obtained directly during contract review.
Board approval follows tier-one Carnegie Hill norms. Strong financial profile, professional accomplishment, primary-residence intent are central criteria.
What to know if you’re selling
The Carpenter authorship and low apartment count are the differentiating marketing assets. Listing copy should foreground both — Carpenter authorship anchors the building in the Park Avenue / Fifth Avenue architectural tradition; the 29-unit scale is verifiably low relative to peers.
Pricing requires apartment-level comparable analysis. Floor altitude, exposure, configuration, and renovation history all matter substantially given the small unit count.
Closing timelines are co-op standard. 6–10 weeks from contract signing to closing.
