Hayfield House was built as a summer home by John and Bertha Conyngham in 1933, during the Great Depression at a cost of over $1 million. The entire three-story structure is steel-framed, with steel floor joists, concrete overlay and fine wood flooring on top. The roof is of Vermont slate and the stone used on the exterior of the house came from the estate’s surrounding fields.

The Conynghams spent several months in Europe in pursuit of many of the rare objects and materials which eventually were incorporated into the building. Mrs. Conyngham’s dressing room was allegedly modeled after the boudoir of Marie Antoinette at the Palace of Versailles and features uniquely curved doors, making the room a perfect oval; the fireplace and mantle were imported from a castle in Europe. The sliding stained glass windows in the former library originally graced a Paris cathedral. To see photos of how Hayfield House looked at that time, visit the Gottscho-Schleisner Collection at the Library of Congress website.  The home was also featured in the February 1935 issue of Country Life magazine.

Today the manor is home to classrooms and faculty and administrative offices.
