At 55,000 square feet and 106 rooms, the Elm Court mansion retains the title of the largest American Shingle Style home in the United States. The structure was built for William Douglas Sloane and Emily Thorn Vanderbilt (granddaughter of Cornelius Vanderbilt) as their summer “cottage” in the Berkshires. The home straddles the towns of Stockbridge and Lenox and sits on a massive parcel of land, giving the owners space to breathe the clean countryside air. Emily’s brother, George, built The Biltmore in Asheville, North Carolina and her sister, Eliza (Lila), constructed Shelburne Farms in Shelburne, Vermont. The home was constructed in 1886 from plans by the great Peabody & Stearns architects. Shortly after the turn of the century, ca. 1901, the couple commissioned Peabody and Stearns again, to vastly enlarge their original house. The additions used both Shingle Style and Tudor Revival motifs, and the result is a structure highly reminiscent of an English country house. William Sloane died in 1915, and Emily Vanderbilt continued to use the summer cottage, and in 1921, she married a summertime neighbor, Henry White, a career diplomat. While Henry White died in 1927, Emily retained the house and kept the grounds running until her death in 1946. The property’s use evolved into an inn in the late 1940s. During the 1950s, it embraced the public for dinners, overnight accommodations and events. Eventually Elm Court’s doors closed, and for approximately 50 years the mansion succumbed to significant theft and vandalism. The property has been listed for sale numerous times in the past decades, after a renovation by the last owners in the Sloane family. It is now listed for $12,500,000!
