Müller-Ury liked California and after painting Archbishop Edward Joseph Hanna in San Francisco in 1923 decided the following year to erect a studio near Huntington's estate. The studio he built was at the corner of Monterey and Shenandoah Roads in San Marino (architect Carleton Winslow), in the fashionable Spanish style with a green tiled roof and in the studio an enormous north-facing window. He placed the Muller coat-of-arms on the east frontage, where it may be found today. The gardens were extensively planted with many varieties of roses including Radiance, Columbia, Rose Marie, Irish Charm, Imperial Potentate and American Beauty which he painted into his canvases depicting the Morgan porcelains begun in New York. Duveen built a bungalow next door to the artist on Shenandoah Road, but seems to have quickly sold it after the death of his client Henry E. Huntington in 1927.
