Located in sunny Southern California, The Zen Cottages offers three different models—as well as custom-built tiny homes—that are typically between 16 to 32 feet long and between 8 to 10 feet wide. Although the larger homes aren't ideal for transporting, the smaller Alpine model is built for long hauls and can even travel through rocky terrain. The interiors are light-filled, simple, and efficient, with careful attention to natural materials.
