Overview of 521 Park Avenue

521 Park Avenue was designed by William Boring, an American-born architect who studied architecture at the Ecole des Beaux-Arts before returning to New York and joining the firm of McKim, Mead and White. The limestone building has been honored with numerous international design awards, including a gold medal for architecture from the Exposition Universelle in Paris in 1900.

521 Park Avenue was constructed as a cooperative in 1911, converted to a condominium in 1987, and currently has 24 units. The building has a full-time doorman, a live-in superintendent, a fitness center, and private storage that transfers with each unit. It also benefits from a location near Central Park, world-renowned restaurants, and top shopping. Pets, pied-a-terres, and flexible financing are allowed.

Carter’s Review

"This impressive 12-story apartment house at 521 Park Avenue on the northeast corner at 61st Street was designed by William Alciprhon Boring and completed in 1911 two years after he had designed 540 Park Avenue on the northwest corner at 61st Street, which has been described, according to James Trager, the author of Park Avenue, Street of Dreams," (Atheneum, 1990), as "the first of the high-class apartments to be built on Park Avenue."

This building was erected as a co-operative and has 27 apartments and was converted to a condominium in 1987. Amenities at this pet-friendly building include a 24-hour doorman, elevator, and fitness center. It is located at one of the city's most prestigious addresses, with Central Park and the finest Fifth Avenue and Madison Avenue shopping a short walk away."
