Richmond, Virginia–based couple Grace Kuhn and David Phinney spent 18 months rehabbing their 31-foot-long Airstream before taking it on the open road with their dog. Inspired by Frank Lloyd Wright’s philosophy of organic architecture, the renovated trailer features a pared-down interior. "I started resonating with colors like browns and grays found in nature," says Grace. "Nature makes makes people feel calm and collected. I wanted to have a space that gives me that feeling."
