Landscape architect Andreas Stavropoulos transformed a 1959 Airstream that he bought off of Craigslist into a live-in structure situated in the garden of a co-op in North Berkeley, California. With just 150 square feet to work with, Andreas "jettisoned the 1950s colors and wall-to-wall linoleum, and moved in with cork flooring, track lighting, fresh, colorful paint, and custom- designed cabinets and furniture to fit the interior topography," he says.
