The Elm Court Estate, a Gilded Age Berkshire Cottage, retains the title of the largest American Shingle Style home in the United States. The structure was built by William Douglas Sloane and Emily Vanderbilt, granddaughter of Cornelius Vanderbilt, along with architects Peabody & Stearns in 1886. The gardens and landscape were designed by Frederick Law Olmsted. Elm Court was originally constructed as a summer cottage to be enjoyed by family and friends. After many structural and aesthetic additions and renovations, the home culminated in a finished version after the turn of the century. In 1919, the Elm Court Talks held at the home ultimately led to the creation of The Treaty of Versailles and League of Nations. Outbuildings include Butler and Gardener cottages, carriage house & stable, greenhouses & caretaker's house and two barns. Significant renovations were accomplished in the early 2000s and continued work is necessary. Listed in the National Register of Historic Places.
