1115 Fifth Avenue is the second building of J.E.R. Carpenter's celebrated Carnegie Hill twin pair — completed one year after 1120 Fifth across East 93rd Street, and built specifically as a cooperative (an early-cooperative configuration uncommon for the 1925-1926 window). The building is, per Carter Horsley, the "virtual twin" of 1120 Fifth: same architect, same developer, completed within one year. The principal exterior distinction is that 1115 Fifth carries arched first-floor windows where 1120 Fifth carries rectangular first-floor windows.
The structural identity rests on three features. First, the Carpenter architectural pedigree at peak Carnegie Hill form — Horsley describes Carpenter as "the leading designer of luxury apartment buildings in New York City in his generation." Second, the Campagna developer credential — Anthony Campagna (1884-1969) was a Naples-born lawyer-turned-developer whose philanthropic legacy includes funding the restoration of Virgil's Tomb at Naples, the Herculaneum excavation, and the Casa Italiana at Columbia University, per the New York Preservation Archive Project. Third, the Arthur Hays Sulzberger resident overlay — the publisher of The New York Times from 1935 to 1961.
The block faces the former Felix Warburg mansion (1908, C.P.H. Gilbert, now The Jewish Museum) directly across the avenue.
Architecture and unit composition
Built in 1925-1926 to J.E.R. Carpenter's design for Anthony Campagna's 93rd St. & 5th Avenue Corp., 1115 Fifth is fifteen stories, limestone-clad, in the Italian Renaissance palazzo idiom that defines Carpenter at peak. The principal exterior distinction from its twin at 1120 Fifth — completed one year earlier by Carpenter for Campagna on the north side of East 93rd Street — is that 1115 Fifth carries arched first-floor windows where 1120 Fifth carries rectangular first-floor windows.
Carter Horsley calls 1115 Fifth "an attractive 15-story apartment house" by "the leading designer of luxury apartment buildings in New York City in his generation." The Carpenter mid-1920s Carnegie Hill duo (1115 and 1120) marks a moment when Carpenter, having won the AIA Gold Medal in 1916 for 907 Fifth, returned to the same Italian Renaissance vocabulary at the more affordable upper-Fifth blockfront.
Anthony Campagna (1884-1969) was a Naples-born lawyer-turned-developer whose philanthropic legacy includes funding the restoration of Virgil's Tomb at Naples, the Herculaneum excavation, and the Casa Italiana at Columbia University, per the New York Preservation Archive Project. The block faces the Felix Warburg mansion (1908, C.P.H. Gilbert, now The Jewish Museum) directly across the avenue — meaning 1115 Fifth's higher-floor apartments look across to one of the great surviving Gilded Age Fifth Avenue mansions, with the Jacqueline Kennedy Onassis Reservoir beyond.
The forty-one apartments distribute across the building's fifteen stories. The 1925-1926 vintage and the Carpenter planning discipline produce substantial ceiling heights, formal entry arrangements, and the generous proportions characteristic of trophy pre-war Fifth Avenue inventory.
Building operations
1115 Fifth operates as a full-service Carnegie Hill cooperative:
- 24-hour doorman
- Live-in resident manager
- Fitness center
- Bicycle room
- Private storage
The operational posture aligns with Carnegie Hill trophy pre-war norms — white-glove staffing and discreet amenity infrastructure.

What to know if you’re buying
The Carpenter twin pair identity with 1120 Fifth is structurally distinguishing. The arched first-floor windows are the principal exterior distinction; verify which sister you are buying at the application stage.
The Campagna developer credential is real institutional context. Campagna's broader philanthropic legacy adds historical depth.
The 50% financing maximum and 2.5% buyer-paid flip tax are operational realities. Factor into all carrying-cost and net-proceeds calculations.
The pied-à-terre restriction is structural. Plan primary-residence positioning at the application stage; case-by-case board posture means substantial diligence on use intent.
The Felix Warburg mansion / Jewish Museum / Reservoir view corridor across the avenue is structurally valuable. Upper-floor apartments looking west carry one of the most-discussed exposure profiles on Carnegie Hill Fifth Avenue.
Pricing benchmarks the $7.15 million median and the $2,339-per-square-foot average per recent CityRealty data. Apartment-line-specific comparables should anchor positioning.
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 Carpenter twin pair identity with 1120 Fifth and the arched-window architectural signature. Both are real structural advantages over peer Carnegie Hill cooperative inventory.
The Sulzberger resident overlay supports cultural-history positioning. Reference in materials where appropriate.
The Carpenter / Campagna architect-developer credential is real institutional context. Position accordingly.
Pricing should reference the median $7.15 million / $2,339-per-square-foot CityRealty benchmark. Apartment-line-specific comparables should anchor positioning.
