The Willis House is a two-story modified American Four Square style house built in 1908. It is the only two-story masonry clad residential building in the town of Encampment. The house was built by Mrs. Lydia M. Willis to be a deluxe house of prostitution and the headquarters of the Willis business empire. Mrs. Willis never finished the inside of the house. In 1931, the house was acquired and finished by Mr. Charles Deo Terwilliger, a locally prominent and respected rancher and merchant.
