In addition to the 21+ acres that can be developed, the property has the Sunnybrae Mansion. Built by a friend of the renowned DuPont family in 1937, the three-story Sunnybrae Mansion, known as "The Jewel of Milford, Delaware", is a beautifully preserved piece of history. With 6,800 square feet of Georgian Revival-style architecture and early 20th-century grandeur, the estate boasts a harmonious blend of family pieces, antiques, and reproductions. And since 2008, this space has been available as a bed and breakfast and event venue for weekend getaways or weddings and celebrations.
