Peabody, Royal C., Estate
Also known as: Wikosco
Why it's listed
Wikiosco is a two and one-half story summer estate house on a landscaped 5.2-acre parcel between Route 9N and the west shore of Lake George. Built of granite ashlar and fieldstone below and half-timbered stucco above, it has stone porches, a polygonal stone tower, a terrace and two tall fieldstone chimneys. Inside are oak beams, carved oak mantels, ornate plasterwork, stained glass, an oval dining room and servants' quarters. It was designed about 1905 by New York architect Charles S. Peabody for his father, Royal C. Peabody, a Brooklyn businessman who founded the Brooklyn Edison Company. The house is recognized as an early and rare Tudor Revival work in the Lake George region and as the most intact survivor of the grand summer houses once known as Millionaires' Row. Many neighboring estates were lost to fire, deterioration and lakefront development, and the rest of the original Peabody property has been subdivided.
Significance in brief: The nomination argues the house is a notable and highly intact example of Tudor Revival residential architecture in the Lake George region, where few examples of the style exist. It also reflects the early twentieth-century resort era of "Millionaires' Row" on the lake's west shore. It is described as the most intact surviving property of that group, and as a rare residential work by architect Charles S. Peabody.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
