Marston was instrumental in establishing Pasadena as a winter resort and then as a thriving community. He and his firm designed 1000 projects, many of which still survive, including cottages and additions to resort hotels, notable commercial and civic buildings such as the Pacific Asia Museum, and the earliest bungalow court. His residential designs span the range of styles from the Arts and Crafts through English Tudor and Monterey Colonial to, most importantly, Mediterranean Revival. This is an important addition to the literature of California's Golden Age of architecture.
