Gaetano Ajello (b. Palermo, 1883; to New York, 1902) designed roughly thirty apartment houses in a twenty-year career, nearly all on the Upper West Side, Riverside Drive, West End Avenue, and in Morningside Heights. He built for the Italian-American developers who made the West Side — B. Crystal & Son, the Paterno Brothers, Anthony Campagna — moving from exuberant Italian Renaissance in marble and terra cotta before the First World War to a restrained neo-Classical idiom in the 1920s. Andrew Dolkart credits his West End Avenue buildings with exceptionally bold three-dimensional ornament. He gave Rosario Candela his first job in architecture.
Who he was
Gaetano Ajello designed roughly thirty apartment houses in a twenty-year career, nearly all of them on the Upper West Side, Riverside Drive, West End Avenue, and in Morningside Heights. Sixteen of them are in our catalog. He carved his own name into the cornerstones — "G. Ajello, Architect" — which is how a number of them were identified later.
He was born in Palermo in 1883 and came to the United States in 1902. Landmark West reports that he trained as an architect in Italy before emigrating, though the LPC's own assessment is blunt: relatively little is known about his life or training. He is not recorded as École des Beaux-Arts trained and received no civic commissions. His offices moved from Broadway to West 34th Street to Vanderbilt Avenue as the practice grew. His work runs from about 1909 to the mid-1920s, and the LPC notes he was active at least through 1932.
His name appears both ways in the record. The LPC uses Gaetano; most preservation and real-estate sources use Gaetan. We standardize on Gaetano and note the variant, because both forms appear across our own building pages.
The work
Ajello built for the Italian-American builder-developers who put up the West Side — B. Crystal & Son, who gave him his first major commissions around 1909; the Paterno Brothers; Anthony Campagna. He was a speculative-apartment specialist working outside the academic establishment, and his buildings were designed to sell apartments.
The early phase is the exuberant one: Italian Renaissance in white and cream marble, glazed brick, and terra cotta. 600 West 115th Street (1911, The Luxor), 235 West 71st Street (1912, The Lucania), 895 West End Avenue (1912, for the Paterno Brothers), 645 West End Avenue (1912, The Halsworth), 255 West 98th Street (1913), and 305 West 72nd Street (1913) belong to it. Andrew Dolkart singles out the West End Avenue pair for exceptionally bold, three-dimensional ornament. Christopher Gray wrote that the early buildings shimmer like marble quarries in the Mediterranean sun.
The later work is quieter. By the late 1910s and into the 1920s Ajello had moved to restrained neo-Classical in limestone, white terra cotta, and light-colored brick, and then to red and brown brick — 885 West End Avenue (1915, developed by Joseph Paterno), 325 Riverside Drive (1920, The Sherwood), 505 West End Avenue (1921), 375 Riverside Drive (1922), 160 Riverside Drive (1922), 300 West 83rd Street (1923), 310 West 85th Street (1923), 17 East 89th Street (1924), and 395 Riverside Drive (1925, The Matincote), which the LPC records as his last known commission.
Recurring details are worth knowing when you walk one: large terra-cotta pilasters framing the entrance, owner initials worked into escutcheons, and a curved lobby stair positioned to screen the elevator.
He also gave Rosario Candela, a fellow Sicilian, his first job in architecture.
How the work is regarded
Ajello sits inside the canon of West Side apartment architects without having been individually honored. The LPC's Morningside Heights designation report names him among the city's prominent apartment-house architects alongside George and Edward Blum, Neville & Bagge, Pelham, and Schwartz & Gross. Dolkart's West End Avenue survey counts nine Ajello buildings against twenty-five by Schwartz & Gross and twelve by Candela.
Only one Ajello building holds individual landmark status, and it is not an apartment house: the Claremont Theater Building on Broadway at West 135th Street, his one known non-residential work, designated in 2006. His apartment houses are protected, where they are protected at all, as contributing buildings in historic districts.
What the credit means for value
The buildings are the argument, not the name. Ajello has no pricing halo of the kind Candela carries, and the practical value in the attribution is what it predicts: a pre-WWI or early-1920s West Side building with generous room counts, high ceilings, and substantial facade ornament.
Layouts are large and simplex. These were built for families taking whole floors or half floors, with segregated service wings. Expect original plans of eight to eleven rooms, most since subdivided or reconfigured. What survives of the original plan is an apartment-level question and materially affects value.
Historic district status cuts both ways. Most of these buildings sit in the Riverside–West End, West End Avenue, or Upper West Side/Central Park West historic districts. That protects the streetscape and constrains window replacement, facade work, and any visible exterior alteration. Confirm the district and the building's LPC history before planning work.
Facade ornament is a maintenance line item. Terra cotta and cast stone of this era require periodic repair, and Local Law 11 cycles on ornamented pre-war facades run more expensive than on plain brick. Review the reserve fund and the most recent filing.
Check the name variant when researching. Records use Gaetan and Gaetano interchangeably, and searches on one form will miss the other.
Buying one today
Establish what remains of the original plan. Room count, ceiling height, window configuration, and the presence of original detail drive pricing within these buildings far more than the address does.
Read the capital position. For pre-war buildings of this age, facade, elevator, roof, and mechanical cycles are the dominant carrying-cost variable. Our Local Law tools check a specific building's exposure.
Compare against the Schwartz & Gross and Candela stock nearby. On West End Avenue and Riverside Drive the comparable set frequently includes buildings by better-known contemporaries at higher pricing. That comparison is where the value case for an Ajello building is usually made.
Co-op policies vary. These buildings converted at different times under different sponsors. Read the specific building's sublet, pied-à-terre, and financing rules rather than assuming a pre-war norm.
Working with The Roebling Team
The Upper West Side pre-war market rewards knowing which building did what, and the Ajello buildings are a well-built, under-narrated part of it. If you are buying or selling in one, a thirty-minute consultation is the right starting point.
