Welcome to the Harold Pratt House & Peterson Hall

The Harold Pratt House was constructed in 1919 as one of New York's grand Park Avenue Mansions. The House consists of six unique rooms connected by a majestic marble staircase. Each event room features original chandeliers, fireplaces and views of Park Avenue. Our adjoining Peterson Hall can be used in conjunction with the House to accommodate larger guest counts. We invite you into our home to host your next event with us at the Harold Pratt House.
