1107 Fifth Avenue is the building that introduced the concept of the New York City penthouse. When the developer George Fuller Company commissioned architects W. K. Rouse and L. A. Goldstone to design the building in 1924–1925, the original specifications called for a roof-level structure that would house a single residence — Marjorie Merriweather Post's apartment — at a scale and configuration no Manhattan apartment had previously achieved.
Marjorie Merriweather Post was the daughter of C. W. Post, founder of the Postum Cereal Company (later General Foods), and after his death in 1914 she inherited what was at the time among the largest private fortunes in the United States. She and her second husband E. F. Hutton (the financier and stockbroker for whom the brokerage was named) wanted a New York apartment at the scale of a great house but also wanted the city convenience of an apartment-building address. The Fuller Company's solution was to design 1107 Fifth around her requirements: she would occupy the top three floors of the building, in a 54-room triplex with 16 fireplaces, 23 staff rooms, a private elevator, an attended private lobby on the ground floor, a dedicated side entrance on East 92nd Street, and dedicated infrastructure (flower room, silver room, wine room, gown closet) at a scale that exceeded most freestanding Fifth Avenue mansions.
The Post triplex was, by most accounting, the first true penthouse in New York City — at the time of construction the largest apartment ever built in the city. The architectural and cultural significance is substantial: 1107 Fifth proved that Manhattan luxury apartment buildings could accommodate residents whose previous expectations were freestanding mansion-scale residences. The Post triplex was conceptual precedent for nearly a century of subsequent penthouse design.
Post lived in the apartment from the building's completion in 1925 until the late 1930s, when she and her third husband (Joseph Davies, then U.S. Ambassador to the Soviet Union) relocated. The triplex was divided in the early 1950s during the building's cooperative conversion, producing the configuration of approximately 26 apartments that the building has carried since.
For buyers, 1107 Fifth occupies an unusual position. The building has the architectural pedigree of a top-tier Carnegie Hill pre-war co-op, the cultural cachet of the Post legacy, and a 26-unit scale that places it among the more accessible (relative to 820 Fifth's 13 or 998 Fifth's 17) inventories among Gold Coast tier-one co-ops.
Architecture and unit composition
The current 26-unit configuration spans apartments ranging from approximately 1,500 sf simplexes to substantially larger duplexes and combinations. The post-division remainder of the original Post triplex — the apartments on floors 12, 13, and 14 — are among the building's most architecturally distinctive units, with retained pre-war detail and views that reflect the original penthouse design.
Pre-war signatures throughout: 10–11 foot ceilings in primary rooms, formal entry galleries, library-living combinations, primary suites with substantial closet infrastructure, kitchens that have been renovated multiple times across the building's 101-year history.
Park-facing apartments on the eastern flank have direct Central Park views, with sight lines across to the Park's Reservoir and the eastern Upper East Side beyond. The building's 92nd Street corner positioning produces particularly strong corner-unit views.
Building operations
1107 Fifth operates as a full-service pre-war cooperative with full-time doorman, attended elevator service, on-site superintendent, and private storage. The building participates in the NYC Cooperative & Condominium Property Tax Abatement Program for qualifying primary-residence shareholders.
Specific policy details (flip tax structure, financing cap, sublet fee, pet policy specifics, pied-à-terre allowance) are not formally published in the manner of many comparable buildings. Buyers should request these specifics directly from property management during due diligence and review them in the proprietary lease and house rules.

Sales context at 1107 Fifth:
- Inventory turnover is moderate. With 26 apartments and standard Carnegie Hill residency norms, the building sees several transactions per year.
- Apartments transact across a range — smaller simplexes have transacted in the $2M–$5M range; larger duplexes and post-triplex configurations have transacted in the $10M–$30M+ range; rare combinations have transacted higher.
- A meaningful share of transactions occur through public listing channels (StreetEasy, Compass private exclusive), though private network access matters for the higher-priced inventory.
What to know if you’re buying
Confirm the specific apartment's history. Apartments occupying portions of the original Post triplex (floors 12–14) have a distinct architectural identity and command pricing premiums reflecting that. Apartments elsewhere in the building are tier-one Carnegie Hill pre-war but without the Post-legacy specifics. The apartment matters more than the building address.
Board approval follows Gold Coast Carnegie Hill norms. Strong financial profile, professional accomplishment, and primary-residence intent are central criteria. Pre-war building's institutional culture favors long-term residents.
Confirm specific policies directly with management. Because the building's policy block is not formally published in the manner of comparable buildings, buyers should obtain current information on the flip tax structure (payor and percentage), financing cap (if any), sublet policy specifics, and any pied-à-terre allowance during the contract review process.
Renovation is constrained by historic district status and pre-war character. Substantial renovation is feasible but must respect the architecture. The board reviews scope and quality.
View permanence is excellent. Central Park east; 92nd Street is a residential side street with stable heights; the surrounding development envelope is built out.
What to know if you’re selling
Marketing varies by apartment. Post-triplex apartments and larger configurations typically benefit from a mix of public listing and private network outreach. Smaller simplex inventory transacts more conventionally through public channels.
The Post legacy is a marketing asset. Buyers interested in 1107 Fifth's cultural and architectural history will respond to apartments that connect to the building's distinguishing identity. Listing copy and broker positioning should make use of this where appropriate.
Pricing benefits from apartment-level comparable analysis. The heterogeneity of the inventory — from small simplexes to portions of the original triplex — means apartment-specific comparables matter more than building-level averages.
Closing timelines are co-op standard. 6–10 weeks from contract signing to closing.
