1115 Fifth Avenue

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.

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.

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.

Verified across Compass building documentation editorial, and broker reporting:

• Pets: Permitted with board approval
• Pied-à-terre: Restrictive — not standardly approved; broker reporting suggests case-by-case
• Financing maximum: 50%
• Flip tax: 2.5% of sale price, buyer-paid
• Subletting: Board approval required; restrictive
• Trust ownership: Subject to board approval
• LLC ownership: Not typical
• Foreign buyer: Substantial board diligence
• Post-closing liquidity: Substantial Carnegie Hill reserves customary
• Board interview: Required; full financial and personal-reference disclosure

The 2.5% buyer-paid flip tax is meaningful at closing — on a $7 million purchase, $175,000 of additional buyer cost on top of mansion tax and standard closing costs.

Market read. $/sf is measured on the latest sales with reliable square footage (2024): a median $1,616/sf (recorded) across 1 sale. The building has traded as recently as 2026. Median listing discount 6.0% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01504-0069). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. 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.

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 should reference recent comparable closings. The relevant comparable is the same line on a nearby floor, adjusted for condition and exposure, not a building-wide median.

Closing timelines are cooperative-standard. Plan for 6 to 10 weeks from contract through board approval to closing.

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 apartment-line comparables. Same-line closings on nearby floors, adjusted for condition and exposure, are the credible anchor, not a building-wide median.

Closing timelines are cooperative-standard.
