A number of years ago I saw a special about the actor Dennis Weaver's home It is quite grand but built with the environment in mind. I just looked it up to pass along here. It is quite interesting. I know he passed away and it was for sale , just a little out of MY price range, lol , but it is interesting and he did fight for environmental causes.
