About

505 West End Avenue was completed in 1922 and designed by architect Gaetano Ajello. Ajello was an unusual architect who designed scores of apartments buildings, most of which are located on the Upper West Side. While he began his professional life as an architect, his active practice spanned only 15 years (1909 to 1924), after which he gave up architectural design in favor of a career as an inventor.
