There's a guy here in Portland, OR who has a 727 he recycled into a home. I remember seeing it in the news when they had to move it from the airport to the property he was putting it on (wings removed, of course). I've always wondered how that worked out for him. Personally, after living in a 14' X 60' mobile home for a few years, the effect of living in a long hallway was pretty annoying after a while.
Then again, those photos on the website look pretty digitally manipulated to me. I wonder if they have actually done this even once. I think I'll take it with a grain of salt for now. I didn't believe the amphibious-RV story either until I saw it in a few different places.
