Built in 1874 and expanded circa 1894 and 1912, the Samuel Douglass House is architecturally significant in Payson as an excellent local example of a vernacular interpretation of nineteenth-century Greek and Gothic Revival styles later adapted to twentieth-century Bungalow and Arts and Crafts styles. The house is also significant for its unique original floor plan, which remains easily discernable. Samuel Douglass was born in 1850 in Salt Lake City and moved to the Peteetneet community in 1863. He followed his father into the general merchandise business, served in several civic positions, and married Emma Jane Dixon in 1874. He was recognized as a successful businessman and supporter of important civic projects such as the Strawberry Valley Project. His house was wired for electricity in 1897 and was also among the first in the community to have running water installed in 1902. The architectural changes made to the house in 1912 reflected growing optimism in the area and incorporated the latest Bungalow and Arts and Crafts styles.
