1133 Park Avenue is a Nathan Korn building commissioned by Harris H. Uris in 1924. Both attributions matter. The Uris family — founded by Harris and built over the subsequent decades by his sons Percy and Harold — would become one of the dominant New York commercial real-estate developers of the postwar era, with a midtown portfolio that included substantial office construction and the Uris Brothers / Tishman commercial assemblage. 1133 Park is an early Harris Uris commission, predating the family's mid-century commercial dominance by a decade-plus, and represents a particular moment in the family's developer history.
The Nathan Korn architectural credential is less common in the Park Avenue corridor than the dominant 1920s firms (Carpenter, Candela, Schwartz & Gross, Blum brothers, Goldstone). Korn's residential work, including 1133 Park, belongs to the broader pre-war Manhattan apartment tradition without slotting into any of the larger-portfolio firm bodies of work.
What structurally distinguishes 1133 Park from peer Park Avenue inventory is the unit configuration. The building has only two apartments per floor across its 16 stories — an unusually low density for the era. By comparison, most tier-one Park Avenue cooperatives carry 3–6 apartments per floor; the larger Carnegie Hill cooperatives (1185 Park, 1185 Fifth) often carry 5–8. Two-apartments-per-floor implies apartment dimensions and exposures that no higher-density peer can match: each apartment occupies half the floor plate, with windowed exposures on multiple sides and direct elevator-landing privacy. This is among the more structurally distinguishing features of any Park Avenue cooperative building.
The cooperative conversion from the original Uris rental occurred in 1954, placing 1133 Park within the post-WWII conversion wave that produced much of the current Park Avenue cooperative inventory.
The Carnegie Hill / 91st-Street positioning is at the heart of the cultural-institution density that defines the upper Park / Fifth Avenue corridor: Cooper Hewitt two blocks west (Andrew Carnegie's former mansion), Jewish Museum one block west (the former Warburg Mansion), the Guggenheim three blocks south, and the Met six blocks south.
For buyers, 1133 Park represents a particular tier of Carnegie Hill Park Avenue inventory: Uris-family developer history at an early commission, two-apartments-per-floor density producing exceptional apartment privacy, 1954 cooperative conversion, and central Carnegie Hill positioning at the cultural-institution corridor's heart.
Architecture and unit composition
The approximately 30 apartments — two per floor across the 16 stories — are uniformly larger and more privately configured than typical Park Avenue cooperative inventory. Half-floor footprints with multi-side window exposures produce apartments materially better than the standard 3–4 apartments-per-floor Park Avenue layout.
Pre-war 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 1924-era luxury apartment design.
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. The half-floor footprint gives each apartment exposures on both an avenue side and at least one side-street side.
Building operations
1133 Park Avenue operates as a full-service pre-war cooperative with full-time doorman, attended elevator, on-site superintendent, and private storage. The two-apartments-per-floor density produces an exceptionally 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.

Sales context at 1133 Park:
- Inventory turnover is low given the 30-unit scale — typically 2–4 transactions per year.
- Pricing weighted toward larger 3–4 BR half-floor configurations — typically $4M–$12M depending on apartment size, floor, exposure, and renovation.
- Public listing through StreetEasy and Compass private exclusive is standard; the larger configurations more frequently transact through private channels.
What to know if you’re buying
The two-apartments-per-floor density is the structural distinguisher. Apartment privacy, light, exposure count, and elevator-landing intimacy materially exceed typical Park Avenue inventory. This is the building's most differentiating feature.
The Uris-family early-commission history is a verifiable provenance asset. The 1924 commission predates the family's commercial-real-estate dominance and represents an authenticated piece of postwar New York developer history.
The 30-apartment scale produces limited annual turnover. Patient pricing and apartment-level comparable analysis matter.
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.
Renovation is constrained by historic district status. The board reviews scope and quality with attention to preservation of original detail.
What to know if you’re selling
The two-apartments-per-floor configuration and the Uris-family commission history are the differentiating marketing assets. Listing copy should foreground both — the density structure is verifiable and rare, and the Uris commission is a piece of authentic New York developer history.
Pricing requires apartment-level comparable analysis. Floor altitude, exposure, configuration, and renovation history all matter substantially.
Closing timelines are co-op standard. 6–10 weeks from contract signing to closing.
