246 West End Avenue, designed by J.E.R. Carpenter and completed in 1913 for developer S. Fullerton Weaver, showcases Carpenter’s signature pre-WWI style of two grand apartments per floor with spacious reception rooms, multiple bedrooms, and separate servants’ quarters. Each apartment had private elevators for added privacy. Carpenter, educated at MIT and the École des Beaux-Arts, designed several similar buildings including 960 Park Avenue and 550 Park Avenue. His later works, like 173-175 Riverside Drive, featured smaller apartments on larger plots. He also designed the 54-story Lincoln Building near Grand Central Terminal in 1930.
