The house he built in 1917, called "Casa Dracaena" (a.k.a. "El Hogar" and Heberton House), was an immediate success. Images of it were used to sell cement and tiles among other goods, and Smith quickly found that his neighbors wanted to live in houses like it. Before long he stopped painting and took up working as an architect full-time in Santa Barbara. His plans to return to Europe after the war were abandoned, and he remained in the Santa Barbara area for the remainder of his life. Before his death in 1930 Smith designed some 80 homes in Santa Barbara County alone, and worked nationwide.
