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.
