Although I have absolutely no numbers with which to back up my hunch, I would bet that dressing up a trailer – or drastically modifying it as the case seems be with the TrailerWrap Project – isn't going to be any less expensive than building a modest little modern house from scratch.
I have the same suspicion of shipping container houses. Just getting those behemoths settled on the site seems daunting . . .
Marcel Breuer wrapped his trailer way back in 1949 or so. His Wolfson Trailer House surrounds a 1948 Royal Mansion Spartan Trailer, which serves mostly as the house's kitchen and dining area. I think the house and studio on 10 acres in Duchess County, NY, is still for sale by our friend, the painter David Diao. – GF
