Thorsen House by architect brothers Greene and Greene, Berkeley, CA.
I'd heard a story that it's owned by a Cal fraternity and that you could just knock on the door and ask for a tour. So the next time I was in the area I did just that. They've always got some pledge who's been instructed in the history and the architecture of the place, and a couple of them were more than happy to show me around.
(A much friendlier atmosphere than the USC docent-led tours of the Gamble House in Pasadena!!!)
Ps. Thorsen House is in the Berkeley neighborhood designed by Olmstead!!
It was of paramount importance to the Greene's that you be able to see and understand how the house fit together, and so exposed joinery abounds.
The "prow" of the "ship"
Thorsen had some kind of sailing/shipping background.
