I used use to think in about my dream house time ago. I spent a lot of time thinking about it in the past. I used to imagine how big it would be or comfortable it would be. One day I knew learned about "Earthship" and everything had made sense to me. This These contructions are made by from adobe and recycled materials. This houses has a water and solar natural powered systems. In fact, The most important part of the house is the huge garden, where you can grow your own vegetables and fruit trees. 

Now, I think this would be like heaven, a peaceful and rewarding life with a small and warm house. Of course, pets also would be happier running and playing in nature.

Very good! I have also heard of earthships. Very interesting!
