George W. Denton House

The George Washington Denton House (also known as the Greta–Theo Holiday House) is a historic home located in the Incorporated Village of Flower Hill, in Nassau County, on Long Island, in New York, United States. It was built sometime between 1873 and 1875. It was listed on the National Register of Historic Places in 1985 and was designated a Village of Flower Hill Historic Landmark in 1996.

Description
The home is a rectangular, 2-story wood-frame building with a two-stage rear service ell in a vernacular Italian Villa style. It features a $2 1/2$-story engaged tower, semi-octagonal bay windows, and an L-shaped wraparound verandah.

Also on the property is a brick ice house built into the side of a hill.

The Long Island Rail Road's 1877 guidebook, "Long Island & Where to Go", made mention of this home; the George Washington Denton House is one of four places of interest in the Roslyn area to be mentioned in this publication.

The home is featured in the Roslyn Landmark Society's 1986 house tour guide, on pages 414 through 423.

History
The house was built at some point between 1873 and 1875 by lawyer George Washington Denton.

In 1919, Allene Tew Buchard, a socialite from Locust Valley and the wife of Anson Wood Buchard, purchased the Denton House and the rest of the property. She named the house the Greta–Theo Holiday House; she named it after her daughter Greta and her son Theodore – both of whom died one year earlier from the Spanish Flu.

In 1930, Buchard donated the property to the Girls' Service League of America, following her husband's 1927 death. She donated the property upon moving to Europe after remarrying to Prince Heinrich XXXIII.
