A few weeks back I watched a movie called "Tiny." It's on Netflix, so you should check it out too. The movie talks about the movement of tiny homes and interviews a few different people that have built their own. It also follows a guy that is taking a summer to build his own tiny home.
I love the idea of living in a small space, and if if we had fewer pets I think I could make that happen without much difficulty. Efficient design is the only way you can make a tiny house work and many people do a lot with very little space.
I came across an article on Collective Evolution that talks about the financial freedom a tiny home can provide. (Read the whole article here). Although money is not necessarily the reason a lot of people choose to live in tiny homes, it is a nice perk! The article also shows some very cute spaces. I have picked out a few favorites below.
