A few year ago, a friend of mine mentioned his idea for building very small houses that were green and that anyone could afford. The idea is that they could be built on a very small piece of property, could be moved if necessary and that you didn't have to have loads of cash to own your own home. Fast forward to 2010 and the idea has now turned into reality. Unfortunately, it wasn't my friend who started these companies, but still the same great concept. When I first started reading about these homes, I was blown away. Unbelievably small square footage used in the most creative ways, great designs and relatively inexpensive. Love, love, love it!
