Bigger isn't necessarily better, especially when you want to live sustainably. At least that's what these small home enthusiasts live by. Giving up the luxury of space, tiny-home owners and builders opt instead for a more eco-friendly, less resource intense way of living. By building homes with high ceilings and planting them in open spaces, they still maintain the illusion of space around them. These homeowners are using less heat, electricity and raw materials -- and they might just make you reconsider how important space really is to you. What do you think-- could you live in a 10 by 10 foot space?
