The Donaldson Futuro is significant as an example of America’s collective confidence as a leader in space flight, technological advancement, and economic prosperity. Designed by Finnish architect Matti Suuronen, this space-age home was the first Futuro to arrive in California, in 1969, and the only Futuro in California to obtain a building permit for residential occupancy. Its modern futuristic space-age design, materials, and workmanship retain a high level of integrity from its period of significance. The property is identified as the Donaldson Futuro in recognition of owners Wayne and Laurie Donaldson’s extensive restoration effort that successfully preserved this fragile resource and raised the profile of early mid-century plastic buildings. It is California Registered Historical Landmark No. 1062 and was placed on the National Register of Historic Places by the United States Department of the Interior on January 4, 2021.
