Bill Gates's House

Researching for a theater set, I went hunting for photos of Bill Gates's house.  Although it's listed on architects Bohlin Cywinski Jackson's website as "private client" it's identified elsewhere on the internet...  Besides, who else could afford this?

An interesting (and large) "green" house in the unostentatious regional wooden style.  Inside, it has some rather deconstructivist detailing.  Click on the link below the photo to go to an Examiner article that has more photos.

Question: is it still "green" when a single family house reaches 50-60,000 SF?
