I love the idea of modular houses, the ease of use, the power in structure, but finding something that I would trust to withstand Florida's weather was an issue. Steel Shipping crates seemed to be an amazing option. They are spacious and strong, and the best of all, modular.
My favorite though, is that there are SO many of them, once you start building, you can keep going forever. Of course this picture is just an example... Our plan is much simpler...
