David Greene at Dwell notes that Americans have been living in prefabs for years- "they`re called "Park Models," meaning they`re wheel-less RVs designed to stay put in a trailer park. {Malibu is full of `em.} The problem? Most are fugly. Outside, they look like a log cabin or faux colonial. Inside, they look like a set from The Golden Girls."

Greene writes that prefabs like Chris Deam`s modern unit for Breckenridge have fallen off the radar, and wonders what has happened to the concept. In fact, I suspect that the concept will continue to take off. There is a vast infrastructure of trailer parks around North America that are due for change and upgrading, and a few visionary park operators are beginning to look at the market for modern.
