Sustainable Hobbit Hole Home

This incredibly cozy picturesque ‘hobbit hole’ house is the ultimate blend of unique style, sustainability and building on the cheap. Stone and mud from preconstruction digging and remnant wood from nearby forests were the primary building materials – all as local and low-impact as possible. Natural light floods in from above, human waste is composted and water comes from a nearby well. Using rough and raw materials not only made for a more eco-friendly dwelling but imbued this amazing residence with unique character for under 10 dollars per square foot of construction. (Source)
