Please join us for our 2026 Country House Benefit at HAYFIELDS HOUSE — a private residence in Mill Neck, designed in 1926 by architect Bradley Delehanty (1888–1965), who was known for designing Long Island estates. Delehanty studied at École des Beaux-Arts in Paris and received a degree from Cornell University.

Sponsorship packages and tickets are available now for purchase below. 

We are very grateful to this year’s Country House Benefit Co-Chairs for their support and dedication.

One of Delehanty’s earliest new country house commissions, Hayfields House was designed for Philip A. S. Franklin (1871-1939), president of the International Mercantile Marine Company, the parent company of the White Star Line, which built the Titanic.
