Harold Pratt House




Home to the Council on Foreign Relations, the Harold Pratt House was constructed in 1919 as one of New York’‘s grand Park Avenue mansions. It is an ideal location for celebrations, weddings, dinners and conferences.

The house features a marble stairway connecting a variety of beautiful spaces including a Library, Reception, Drawing, Sitting and Ballroom. All feature cathedral ceilings, fireplaces and original chandeliers.
