The Braes

The Braes is a historic Jacobean-style mansion in Glen Cove, New York constructed for George Dupont Pratt in 1912. Occupying 40,000 square feet, it is among the top 100 largest houses in the United States. It is the largest of the six Pratt estates on Long Island. Since 1947, it has been home to the Webb Institute of Naval Architecture. The building is situated on 3 terraces above the Long Island Sound.

It is the second house to sit on this site. The first house, a Georgian revival styled house, was also built for Pratt in 1902. The Pratts tore it down when they decided the Jacobean style suited them better. Both houses were designed by James Brite of the architectural firm of Brite & Bacon.

The Braes was built on an estate known as Dosoris Park, which land was originally purchased by Pratt's father. Herbert and eight of his siblings all built houses here, but The Braes was the largest.
