The William R. Thorsen House, also known as the Sigma Phi-Thorsen House, is a historic residence in Berkeley, California. Built in 1909 for William and Caroline Thorsen, it was the last of five so-called "ultimate bungalows" to be designed by Charles and Henry Greene, principles in the architectural firm of Greene & Greene. Three others are in Pasadena, and one (Pratt) is in Ojai, California. The term "ultimate bungalow" was coined by Robert Judson Clark in the 1960s, but is technically a misnomer, since bungalows are typically small, one-story houses. However, "Craftsman bungalows" of the early twentieth century do share some characteristics with the larger houses of Greene & Greene, including the Thorsen House.
