a remodelling and enlargement of the house. This work was carried out by the local architect Arnout Cannon from Poughkeepsie. The style of the mansion was changed to a Queen Anne style country house. A third floor, a multi-gabled attic, a circular five-storey tower, a porte-cochère, and a verandah were added in the process. The new interior of the building was designed by Joseph Burr Tiffany, a cousin of Louis Comfort Tiffany. The rooms of ground floor were done in Historic Revival Style and in the aesthetic movement style using materials such as use mahogany, leather, stained glass, and linen. In parallel to the redesign of the mansion proper, the grounds of the estate were transformed by landscape architect Calvert Vaux according to the American Romantic Landscape style. Vaux's design comprised the creation of a network of drives and trails, the positioning of specimen trees and ornamental shrubs as well as the placement of an eclectic set of out buildings such as a carriage house, a gate lodge, and a potting shed. Gazebos and garden seats were positioned at carefully chosen vantage points. Preservation Daisy Suckley was instrumental in forming Wilderstein Preservation, a private non-profit organization. She opened the house to the public at Christmas 1984. The society is a recognized charity by the IRS; donations are tax deductible. Although little restoration work was carried out during her lifetime, responsible stewardship is becoming the norm now that concerned parties are supplying funds. For example, the tower was renovated in 1994, the main roof replaced in 1997, the siding on the second and third floor was restored in 2001, repairs on the porte-cochere and the north porch in 2002, and restoration work on the verandah in 2006. Location The address of the mansion is 330 Morton Road, Rhinebeck, NY 12572, New York. It is a contributing property to the Hudson River Historic District and a National Historic Landmark.
