1125 Fifth Avenue is one of Emery Roth's most refined Fifth Avenue projects and — per public records — "one of the most attractive" buildings "in the very desirable and pleasant Carnegie Hill neighborhood." The defining structural feature is the one-apartment-per-floor configuration: fourteen full-floor residences, an air of privacy and exclusivity rare even on Fifth Avenue.
That one-apartment-per-floor configuration sets the building at the smallest scale of any prestige Carnegie Hill cooperative — only the multi-floor penthouse triplex (currently listed at $50 million per public records) exceeds full-floor scale. The configuration is the work of a notable pairing. The Roth architectural pedigree at refined Neo-Renaissance form — the same hand behind 875, 993, and 1133 Fifth — produced what is widely considered the most attractive building in Carnegie Hill, while the Minskoff developer credential carries its own arc: Samuel Minskoff began as a Russian plumber whose sons (Henry, Jerome, Myron) built Sam Minskoff & Sons into a major New York developer, with later projects at The Brevoort, 710 Park Avenue, 1 East 66th Street, 1 Astor Plaza, and the MGM Building.
Architecture and unit composition
Built in 1925 to Emery Roth's design for Samuel Minskoff of Sammis Holding Corporation, 1125 Fifth Avenue is fourteen stories, Neo-Renaissance, executed in limestone and brick. The defining configuration is one apartment per floor — fourteen full-floor residences. The building converted to cooperative ownership in 1951.
Roth's other residential buildings on Fifth include 875, 993, and 1133. The Roth Neo-Renaissance vocabulary at 1125 is more compressed and elegant than at his larger postwar work. The one-apartment-per-floor plan creates an air of privacy and exclusivity rare even on Fifth Avenue. The building is widely considered the most attractive in Carnegie Hill.
Samuel Minskoff began as a Russian plumber whose sons (Henry, Jerome, Myron) built the family firm Sam Minskoff & Sons into a major NYC developer. Later Minskoff projects include The Brevoort, 710 Park Avenue, 1 East 66th Street, 1 Astor Plaza, and the MGM Building. The 1125 Fifth commission anchors the family firm's prewar luxury residential body of work.
The full-floor configuration produces substantial corner exposures, generous ceiling heights, and the configuration profile of trophy pre-war Fifth Avenue inventory at the smallest possible scale.
Building operations
1125 Fifth operates as a boutique Carnegie Hill cooperative:
- Full-time doorman
- New fitness center
- Additional storage
With only fourteen residents, the building has the operational profile of a very small private club. The amenity infrastructure is deliberately reserved relative to peer Fifth Avenue cooperatives — the institutional identity rests on the architectural pedigree and the one-apartment-per-floor configuration rather than on amenity-maximalism.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01505-0069) 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 one-apartment-per-floor configuration is structurally distinguishing. No other Carnegie Hill cooperative carries the same scale; the operational identity approaches a private club.
The $1.1 million dollar-denominated financing cap is the most restrictive on the corridor. Plan accordingly — on trophy units the policy effectively requires all-cash.
The permitted trust ownership is uncommonly flexible. Trust transfers and trust purchases are both permitted with board review — a posture rare for prestige Fifth Avenue cooperatives.
The 3% buyer-paid flip tax is meaningful at closing. Factor into all carrying-cost and net-proceeds calculations — on a $15 million purchase, $450,000 of additional buyer cost.
The Roth / Minskoff architect-developer pedigree is real institutional context. Both names connect to substantial 20th-century New York residential history.
The PH151617 $50 million listing benchmarks the trophy penthouse market. The 8th-floor full-floor at $8.95 million benchmarks mid-tier full-floor inventory.
Closing timelines are cooperative-standard. Plan for 6 to 10 weeks from contract through board approval to closing.
What to know if you’re selling
Marketing should emphasize the one-apartment-per-floor configuration and the Roth architectural pedigree. Both are real structural advantages over peer Carnegie Hill cooperative inventory.
The permitted trust ownership policy expands the trophy buyer pool. Position accordingly.
The Minskoff developer credential and the broader family firm's body of work (The Brevoort, 710 Park, 1 East 66th, 1 Astor Plaza, MGM Building) are real institutional context. Reference where appropriate.
Pricing should reference the PH151617 $50 million listing and recent full-floor comparables. The boutique fourteen-unit scale means individual closings move building-wide pricing benchmarks.
Closing timelines are cooperative-standard.
