Thompson, W. B., Mansion
Why it's listed
Perched on a hill above the Hudson River in northwest Yonkers, this limestone country house was completed in 1912 for William Boyce Thompson, a mining engineer, financier and philanthropist. The architects were Carrere and Hastings, the same firm then working on Henry Frick's Fifth Avenue mansion. The house is a Renaissance Revival design with a seven-bay east front, a Palladian arcade on the garden side, loggias, and a sixteenth-century Italian church facade built into its north wall. Inside are walnut and oak paneling, coffered ceilings, imported fireplaces, a three-story stairhall and an indoor swimming pool. Landscaping by the same architects includes a walled classical garden and a theater replica. It is one of few early twentieth century estates in Yonkers to survive largely intact, and the only local country house by this firm. After Thompson's widow died in 1950, the property passed to the Archbishopric of New York and later became part of a college, which continues to use it.
Significance in brief: It is one of the few largely intact early twentieth century palatial residences left in Yonkers and the only Carrere and Hastings Renaissance Revival country home in the area. It is valued for its architecture and as a record of the lifestyle of America's early twentieth century millionaires. Its unique features reflect the tastes of its builder, financier and philanthropist William Boyce Thompson.

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.
