It is located in Sands Point on the North Shore of Long Island in Nassau County, New York.

[2] Once construction had completed, the 300-acre (1.2 km2) estate needed 17 house servants and 200 farmers and groundskeepers to maintain its upkeep.

The walnut-paneled Library was copied from the palace of King James I; relief portraits of literary figures still decorate the plaster ceiling.

The Billiard Room featured a gold leaf ceiling, hand-tooled leather wall covering, and carved oak woodwork from a 17th century Spanish palace.

The U.S. government declared the estate as surplus and eventually gave the deed of the property to Nassau County, New York in 1971.
