Incredible Trailer Home in France!!

The outside looks a lot like an old train/subway car that someone turned into a place to live. But once you step inside, WOW! not at all what you would expect. This regular small trailer looks very spacious inside with all white walls and smartly placed mirrors. Color abounds in the interior making this quite a charming place to live.
