Trygveson
Why it's listed
Built in 1923 on Pinestream Road in northwest Atlanta, Trygveson is a villa in the Italian Baroque manner, finished with stucco walls and a red tile roof. It was originally set on 18 acres, though only about 2 remain. The house draws on elements of three Italian villas: Cuzzano near Verona, Gori in Siena, and Spada in Rome. Philip Shutze and the firm of Hentz, Reid, and Adler were responsible for the siting, the landscape design, and the house itself, although the landscape has since been much altered. Inside, Baroque ornament is prominent, and one mural by Allyn Cox survives. Andrew Calhoun, a real estate man and son of an eye doctor, was the original owner. The name is a Welsh interpretation of his wife's name, Mary Guy Trigg. The house was quickly described as one of the show places of Georgia, and it is considered the state's best Italian Baroque villa.
Significance in brief: The nomination calls it the best example of an Italian Baroque villa in Georgia. Its design draws on three Italian villas (Cuzzano, Gori and Spada) and reflects the work of Philip Shutze and the firm Hentz, Reid, and Adler. The interior spaces and detail are described as superb, and the house was called one of the show places of Georgia soon after completion.
