The Thorsen House is a Berkeley architectural treasure and has touched the lives of many thousands of people. It is now on the National Register of Historic Places and is a recognized Berkeley Historic Landmark. The house is gorgeous inside and out, and the true wonder of it is that it is still used as a house and shared with the community under the stewardship of the Sigma Phi fraternity.
The William R. Thorsen House, often referred to as the Thorsen House, was built in 1909 by William Randolph and Caroline Canfield Thorsen. Designed by Henry and Charles Greene, of the renowned Pasadena firm of Greene & Greene. The House is considered as the last of four ultimate bungalows and is the only one located in Northern California. William Thorsen was a lumber baron from Michigan who retired to California and purchased a lot in Berkeley. His wife, Caroline, is the sister of Nellie Canfield Blacker of the Robert R. Blacker House. She was inspired by the Greene brothers' work and also wanted a wooden house like her sister's as she was the wife and daughter of men in the lumber business.
Purchased in 1943 by the Sigma Phi fraternity for their U.C. Berkeley chapter, this famous Craftsman house has now been occupied longer by Sigma Phi than it was by the Thorsen family. Sigma Phi takes the utmost care of their beloved "frathouse" and people are shocked when they walk inside and see the pristine condition this house remains in.
The active members of the fraternity generally give free tours to the public every Saturday, between the hours of 9:00 am and 2:00 pm. The house shares a close relationship to the Gamble House in Pasadena, and ongoing preservation efforts have lead the house to become a non-profit entity under the guidance of the California Preservation Foundation. There is currently a major fundraising effort underway to restore certain deteriorating features of the house and seismically retrofit the house due to it's proximity to the Hayward fault.
