Right, but his house is built into the cliff specifically to help with thermo/electricity costs. At least according to what I read. Interestingly enough his house is worth something like $150MM and his neighbors are $8M. If you Google map him (boring weekend) the person directly across from him has a fairly normal house with very normal cars (old 4runners, etc.).

Evidently he bought that land in 1988.

The most interesting part of google mapping it was his curious gate. He's got a really weirdly designed entry gate. Couldn't find any info on it, though. My friends usually have their initials or their "crest" as gates.
