This approximately 260 sq ft, earth sheltered underground Hobbit Hole is within a permaculture-based, sustainable, off-grid village in California.
It features colored bottles built into the wall, stained glass windows, center tree pillar with atrium windows above, and medieval Celtic Cross above the Hobbit Hole (outside and atop) giving it a Hobbit Church feeling.
