51 Fifth Avenue is the architectural curiosity of Lower Fifth Avenue — the rare residential cooperative designed by Thomas Lamb, an architect whose portfolio is otherwise defined by the great American theater commissions of the 1910s and 1920s. Lamb is best known for the third Madison Square Garden (1925, demolished 1968), the United Palace Theatre (originally Loew's 175th Street, 1930, surviving), the Ziegfeld Theatre (1927, demolished 1966), and a substantial body of cinema, theater, and entertainment-venue design across North America. A 1929 luxury cooperative apartment building on Lower Fifth Avenue is a structurally distinct credential within Lamb's body of work, and the building's particular architectural register — its proportions, its facade discipline, its specific approach to the prewar Manhattan apartment-house idiom — carries the traces of the theater-architect sensibility that defined Lamb's broader portfolio.
The building was completed in 1929 at the absolute terminus of the Lower Fifth Avenue prewar cooperative cycle — the construction window that began in 1922 at 39 Fifth Avenue and that the October 1929 stock market crash effectively closed. The 1929 vintage places 51 Fifth at the architectural maturity of the corridor's prewar building cycle, with the building incorporating the structural and design lessons of the preceding seven years of Lower Fifth Avenue construction (One Fifth, 45 Fifth, 30 Fifth, 33 Fifth, 24 Fifth) and executed at a scale — 16 stories, 89 apartments — that produces a mid-size cooperative configuration distinct from both the boutique cooperatives (45 Fifth, 43 Fifth) and the institutional-scale buildings (24 Fifth, One Fifth) on the corridor.
The building's geographic position — at the 12th Street corner immediately adjacent to the Salmagundi Club at 47 Fifth — places 51 Fifth at the northern terminus of the 11th-and-12th-Street block that produced the most architecturally distinguished concentration of Lower Fifth Avenue cooperative inventory.
For buyers, 51 Fifth represents a particular position in the Lower Fifth Avenue market: the Thomas Lamb architectural credential, the 1929 maturity-of-the-corridor vintage, the mid-size 89-unit scale, and pet-friendly cooperative policies.
Architecture and unit composition
The 89 apartments distribute across the building's 16 stories in configurations ranging from studios through penthouse units. The facade is the prewar brown-brick idiom characteristic of late-1920s Lower Fifth Avenue construction, articulated by a graceful limestone entrance detail.
Apartment interiors retain the prewar proportions and detailing characteristic of the corridor's 1929-vintage construction — substantial ceiling heights, oak-strip flooring, the architectural vocabulary that distinguishes the prewar cooperative tier from the postwar mid-century inventory.
Building operations
51 Fifth operates as a mid-size full-service cooperative with full-time doorman, live-in superintendent, and a fitness center. The cooperative is pet-friendly — a meaningful structural feature that materially expands the buyer pool. Specific board policies on financing percentages, subletting frameworks, pied-à-terre permissions, and flip-tax structure should all be confirmed against the offering plan during due diligence.

Sales context: building-level averages have run approximately $1,611 per square foot across recent 10-transaction windows; pricing varies meaningfully by exposure, floor, and apartment configuration.
What to know if you’re buying
The Thomas Lamb credential is structurally distinguishing. Lamb's residential commissions are rare; the 51 Fifth Avenue attribution is a specific architectural-pedigree advantage that materially distinguishes the building within the corridor.
The 1929 vintage represents the maturity of the corridor. Late-1920s Lower Fifth Avenue construction incorporates the structural and design lessons of the preceding seven years; the apartment proportions and the facade discipline are correspondingly developed.
The pet-friendly policy is meaningful. Materially expands the buyer pool compared to the prewar Lower Fifth Avenue norm.
The geographic position is structural. Immediate adjacency to the Salmagundi Club and the 11th-and-12th-Street architectural concentration places 51 Fifth in the corridor's most distinguished block.
Greenwich Village Historic District protection applies.
Confirm operational specifics directly. Subletting policies, financing percentages, flip tax, and pied-à-terre permissions should all be confirmed during due diligence.
What to know if you’re selling
Marketing should emphasize the architectural credential. Thomas Lamb's rare residential commission, the 1929 corridor-terminus vintage, the immediate adjacency to the Salmagundi Club.
Pricing requires apartment-level comparable analysis. Mid-size cooperative inventory produces a moderate comparable base; recent closings on the specific apartment line should anchor positioning.
Closing timelines are cooperative-standard. Plan for 60–90 days from contract through approval to closing.
