Nearly two years ago, I followed reports by Curbed LA, which was tracking the sale of the Office of Mobile Design's ShowHouse.  At the time, the one-bedroom, one-bathroom home was listed at $175,000, and I always wondered what happened with it -- until the other day when Allison Arieff tweeted a photo of the Jennifer Siegal-designed structure on a beautiful desert lot.  The 720 square-foot portable house found a new home.
