“Sunnie-Holme,” Fairfield, Connecticut, ca. 1930, a hand-colored glass lantern slide by John Duer Scott, via Archives of American Gardens, Smithsonian Institution Commons on flickr.
Sunnie-Holme was the summer residence of Annie Burr Jennings, whose father made fortunes in the California gold rush and as an investor in Standard Oil. She designed at least some of the garden, influenced by the writings of Gertrude Jekyll. The house was demolished after her death in 1939 — a provision of her will. There is a photo here.
